windows 7 gadgets display problem Results

Sponsored Links:

Okay so I'm stumped! My gadgets were working fine for about a day after my installation of 7 and then out to the blue none of then are displaying correctly. I don't know if it maybe something I've done (though i don't see how considering I've not changed anything in the system other than the background and theme) or just a common problem but here is a screenshot of what I'm seeing.

The top gadget is the clock, middle in cpu meter, and the bottom is weather.
This is the only problem I'm having with windows 7 so far, and it isn't necessary to have the gadgets but it is nice to have them! So a little help on this "problem" would be appreciated! Thanks ^_^

Greetings. I have just joined Windows 7 forums today. I have noticed that there may be a few threads regarding 'boot up' in Windows 7. However, after performing some small technical tasks, I decided to post the results for the benefit of everyone.
We presently were operating with DSL for a while. Not bad, but slow to upload or download. We had FIOS installed which gave us the benefit of 4.99 GHz download and 2.25 GHz upload. This was quite a difference from 1 GHz download and 768 megabit upload.
To begin, there was an issue the very first day regarding internet and phone. The internet was apparently corrected by conducting line tests at 3:00 a:m. However, the phone was a continual problem for nearly six days. The phone would ring, then a busy signal would occur. Other times, the call would be cut 'dead'; local or long distance. All transmission was carried through a landline.
Following this, or in unison with this, was that my Symantec Endpoint started displaying DOs on legitimate sites, such as Chrome: browser,, etc. I was not aware of this aspect at the time (DOs) being an option in Symantec. In the same instant, the Symantec Live Update was X'd out. Could not remove Symantec, after trying to correct the Live Update. I did a complete recovery, which lasted about eighteen hours, going through every aspect of the computer.
After spending nearly five days on the telephone with FIOS, the problem was corrected by replacing the external box (don't know the name of the box).
When the system (Windows 7) was back to somewhat normal, I noticed the boot time had dramatically increased to nearly an additional 40 seconds. Prior to performing a recovery, I had taken pictures, or logged every feature which I had previously set in place. In this respect, I could not understand why the 'boot time' was increased after performing a recovery, and installing the same identical items. Nearly one day later, I disabled the Windows gadgets. I gained about 35 to 40 seconds, in terms of a quicker start up. Prior to this, all startup programs were not running upon start up, including security. By the process of a step by step analysis, I remembered the Windows gadgets; to disable. There has been some mention of Microsoft as applying a patch for their gadgets, and of presenting a security issue.
Let me say this much. Boot up time was anywhere from 1:30 and longer with Windows gadgets being enabled. Upon disabling Windows gadgets, boot up time is about 50 seconds. That is some difference. I even disabled HP games prior to this, and that did not help. So, by process of elimination, I found that Windows gadgets presents a significant detriment to the system.
I hope that this may be of assistance to any that may be stumped by following the required steps for faster boot-up. Any and all replies are most welcome.

Consider the following scenario. After installing Internet Explorer 9 on a Windows 7 SP1 machine, when you try to add a Calendar gadget on the desktop, the Calendar gadget can be added successfully but might not be displayed properly. When the problem...



I installed Windows 7 Enterprise 64bit (not the beta or the RC) on my Shuttle XPC Quad Q6600 with Intel G33/G31 chipset with the Intel driver for the win7 RC (version
There are some issues...
Mainly when waking up from sleep (garbled display, incomplete graphics, windows in unicolor, etc.)
I've gotten messages from win7 saying that igdkmd64.sys is responding slowly and is causing the system to wake up sloooooooowly from sleep.
The display I use is an Acer p224w.
I must admit that the sleep issue doesn't occur all the time. What does happen all the time (when the display is put to sleep) is the following:
- continuous connect/disconnect hardware ping sound (i suppose from the display)
- running applications windows are resized to 640x480 when the display comes back from sleep
- some desktop icons changed place

What happens sometimes, usually when the machine comes back from sleep
- usually same as above
- sometimes, background is black, desktop icons do appear, but cannot be clicked
- it seems to be linked to explorer.exe, cos I got a few messages that it is unresponsive
- sometimes, when I press ctrl+alt+del, I can log-off or restart, sometimes nothing works anymore
- logging off and back on fixes the unresponsive explorer / graphics issues
- sometimes the display just doesn't come back from sleep at all

Another strange thing that happens (dunno if they're related) is that sometimes when the machine wakes up, I get a "You're computer is low on memory. Save your files and close these programs: Firefox.exe"
Now, I have 4 gigs of ram (no paging file) and only AVG antivirus, Outlook 2007 and firefox 3.5 running.
The memory desktop gadget says 93% used...

Any thoughts as to what could be the problem here...?


I'm running Windows 7 32bit. When Windows start, the gadgets isn't display.
Even, it's not displaying "Windows Desktop Gadgets has stopped working" message.
When I right-clicked on my desktop and select the gadgets, the gadgets isn't displaying too. I go to the Windows Task Manager and view the process, the 'sidebar.exe' is not shown. When I search on the programs and run 'View list of running Gadgets', it's displaying "Windows Desktop Gadgets has stopped working" message. I already try a lot of a methods to fix it, but it's not worked for me.
Here is the technical details of it.

Any help would be greatly appreciated.


Whatever gadgets I choose to display, they show and work O.K., but only until the next restart. Upon that, they just disappear and I have to right-click on the desktop and select "Gadgets" in order to make them show themselves again.

Note: This might be related to my other problem that W7 forgets parts of my Power Plan upon each restart. So it would seem that it just forgets changes made to its configuration upon restarts and/or power losses.

Note 2: I have Windows 7 RTM (Build 7600, from MSDNAA), UAC on default and installed Comodo Security Suite (latest version).

Thanks for the replies in advance.

I recently installed Windows 7 RC1 x64 from the download Microsoft had been providing. I have many questions about it as a new user to Windows 7 and am curious if there are solutions to these, or if they are known bugs. Also, some questions are more general in nature.

1) Sometimes while using various programs (J River Media Center, Mozilla Firefox, Picasa) the window I am in loses focus, though I'm not doing anything other than playing music. I have heard that it may be some kind of filter like ffdshow or Haali or something along those lines takes the focus. But it can be very annoying as I lose the ability to scroll with my mouse wheel, right click, and even type. To solve the problem, I must minimize and then restore the window

2) Networking/Power Saving. I have put Windows 7 on both my laptop and PC. I use the homegroup feature which I really like as the sharing seems to work seamlessly and is very well organized. However, I am annoyed at how when my laptop (or PC)has been idle for several hours, it goes to sleep, or essentially shuts down. I know where to change these options at, but I also want to be cognizant of power usage. What is the lowest power setting I can set my computers to go into and still be accesible across the network. Is there not a way for the computers to go into some kind of mode that is reduced power, but then when called upon, the system awakens?

3) Google Friend Connect. This is not a windows 7 issue, but a question that I have since joining this site. I used the Google Friend Connect option to essentially link my Google account with this one when I registered. This site was the first time I have heard of this. When I go to Google, I don't see where to really "manage" my Friend Connect sites. Is there a place to do so? I only see a method of adding sites I own to the Google Friend Connect Network, not ones I where I am merely a user.

4) Optimizing for performance. This is a big one. I'm not all that skilled when it comes to computer mumbo jumbo. But I have just built a relatively powerful computer and I want to maximize its speed on a day to day usage. I went with 8GB of RAM (DDR2-800) and a Core 2 Quad 2.83GHz system for plenty of power. I mainly use the computer for media playback (I have an extensive library of images, recorded tv shows, movies, music, etc.), internet browsing, email, etc etc. Nothing too power intensive. And I've got all this RAM, (at the moment 1662MB used, 6527MB free). I know RAM is worthless if its not being used, so I am interested increasing the amount of things Windows stores in memory. As I understand it, the system can load from memory much faster than from disk, so I'd like to store things in RAM if possible. What adjustment to settings should I make for my favorite websites to load faster, for my media library within J River Media Center to build faster (along with its cover art, etc? What about searching hard drives? I want it to scream.

5) Desktop Gadgets. I really like these. Used them extensively in Vista and Windows 7 x86 when I used it as well. They generally work (except for a small graphic problem that I cover in 6). However, in Vista and x86 Win7, I was able to install 2 of the same gadgets on the desktop. This was really useful for me for a particular Gadget called iWeather. I was able to view the weather in multiple places on my desktop. Now, I have to use a different weather gadget for each city I want to see, which looks ugly and disorganized. Is there any way to view 2 of the same gadget? Right now, Windows 7 detects that I already have said Gadget on my desktop and asks me if I want to overwrite it.

6) Graphics Driver? I have the latest ATI driver for my 4600 series card that is dated like August 17, 2009 I believe (9.8?) However, occasionally, the font on my computer or size of the gadgets will seem to get aggravated causing things to not display properly, have text cut off, etc. Very annoying, and doesn't happen often, but it takes a reboot to fix. Any ideas? I kind of assumed it was probably a driver issue, but it really could be anything I guess.

7) Powertoys. I know XP had PowerToys which gave you a lot of flexibility over the OS that wasn't available out of the box. Are there any similar programs out there for Windows 7?

Thanks for any help,

I have I3 processor and 2 gb ram windows 7 HB 32 bit . many programs give this error like gadgets , ie . any solutions ?

I'm on Windows 7 Professional, 32-bit.

I think it was safe to assume that I was recently infected with a trojan virus. But was either quarantined or deleted by my anti-virus.

i use the CPU Meter Gadget to keep track of my CPU and RAM usage. It is working but it is lagging. Like the arrow is jumping like from 13% in CPU usage, it would suddenly be at 70% with no smooth acceleration. I also uninstalled, deleted and reinstalled but to no avail.

out of windows, I use a software called Advanced System Care v4. I am also having a problem regarding this one.

The first thing that i noticed is that every time I do a Deep Care, everything works well until it goes to scan for the "Junk File Clean" of ASC v4. A pop up window would say that ASC v4 stopped working and would try to and fix the problem until it finally ask you to close the program. I tried several times to run ASC and still the same thing occurs. I tried unchecking "Junk Files Clean" it worked smoothly. I tried to check only "Junk Files Clean" and A pop up window would say that ASC stopped working again and close the program.

Another thing is that the ASC v4 Icon went missing both in desktop and start menu. i tried to look for the icon via right click on the icon and the icon was there to be selected but it is not displayed whenever i apply it. I unistalled and re-installed my ASC v4 but still no icon. I then rebuilt my iconcache.db so it's okay now.

However, my dilemma with the "Junk File Clean" is still the same - it won't work.
ASC v4 still stops working when scan starts with this one. I don't why.

I am not aware if there are still other problems but this two are currently the only things visible to me. I did an SFC Scan and found no problems, I ran a Malware Fighter software, I ran Registry Fixes, I ran my anti-virus and still they all didn't help.

Can please, anybody, help me?

Attached is a picture of my desktop. I downloaded a CPU Gadget on the net and found that it is working smoothly. I opened the original windows CPU meter to see their difference in movements. Please see their percentages. Both are different.

Running an Intel (R) Core(TM)2 Quad CPU with 8 Gigs RAM and NVIDIA GeForce GTX 280 on Windows 7 (Upgrade from Vista Home). No video card problems, however for some reason desktop background is stuck on one picture (set for slide display) and Gadgets display has disappeared. Changes to Personalization do not work, nor does clicking "Next desktop background". No changes made to computer other than auto upgrades installed by Microsoft. Any solutions? I'm really tired of looking at the same desktop background day in and day out!


I just did a clean install of Windows 7 Ultimate x64 and I'm having a bit of a problem connecting to the internet. The Network & Sharing Center says I have an active connection and I can see packets being sent and received. However, when I open IE8 or FF no web pages can be displayed. They are in a constant state of "Waiting for Reply". To confuse things further, gadgets on my desktop are being updated with an internet connection, albeit randomly. For instance, if I change the zip code on the weather gadget and save it takes up to 15 minutes to refresh the weather for that city.

I know that I have an active internet connection because I have another computer on the same router with no issues (Windows XP). The computer I am having issues with was using Vista previously. I did a clean install to Windows 7 x64 and this is when I started having issues.

I have read in other threads that nvidia has released updated drivers but since I can not connect to the internet I can not update them through that computer. If I wanted to download drivers on the XP computer for the W7 computer, how would I know what model device I have and what drivers I would need? The Nvidia website asks for product, device and series and I have no idea how to find out what I am using so I can get the proper updates.

Here are my stats:
Windows 7 Ultimate x64
AMD Athlon 64 X2 Dual Core Processor 5200+ 2.60GHz
NVIDIA nForce Network Controller

If more information is needed just let me know. I have scoured the internet for help with this so any and all help would be greatly appreciated!

Morning All,

I have got a really odd problem, every time my computer makes any kind of sound I get a blue rectangular box in the top right hand corner of my screen with a number, the volume level displayed. It fades after 3 seconds but pops up EVERY time a system noise or you tube or mp3 etc is played
I am running windows 7 with an acer revo nettop connected by HDMI to my lcd tv
It only appears when HDMI audio is selected (which is all the time for me!)

It is the Windows Media Centre volume icon. I have attached a screen grab and circled it

I have completely disable windows media centre in control panel, windows programs and features,
I have also reinstalled all sound and hdmi drivers

Please have a look at the attachment

Thanks for any ideas

Does the box pop up when your Media Center is running?

My system is a Dell desktop running windows 7 64-bit home premium. I have 8 GB RAM, and a 2.8 GHz Intel Core i7 processor. I was fooling around with windows backup and restore and I created a new user account. I rebooted and noticed that in my primary user account, the one I always use (not the new one), a good portion of my desktop icons had disappeared. I also noticed that in the new account I created, only 1 of the many desktop icons displayed. Most, if not all, of the disappeared icons are shortcuts to applications such as VMWare, itunes, YouTube Downloader, etc. But these applications are still there within the start menu under "All Programs". Unfortunately, I'm not sure exactly how long the missing icons have been gone. I just noticed the problem a few days ago.

Here's another strange thing. All the previous versions of my desktop folder, dating back to last July, seem to contain only the shortcuts that display now, not the missing icons, and I'm pretty sure that all the icons were present back then. It doesn't make sense. How could all the icons display if they weren't in the desktop folder to begin with? I have no idea of how I could have deleted only some of the shortcuts either. I realize I could just recreate the shortcuts on the desktop, but something weird happened here, and I'd like to know what it is. Also, there is one icon that displays that isn't in the desktop folder but is in the "Links" folder. It's a DVD-making application called Corel WinDVD 2010.

I tried rebuilding the icon cache and it didn't bring back the missing icons. All it did was change my Corel Video Studio application icon from a generic one to the little camera logo like it's supposed to be. There are still no icons displayed on the desktop of the NEW user account that I created, except for the Corel WinDVD 2010 one and a gadget for my Corel Video Studio Pro X application (it's a movie editing software package). Strangely, the gadget does appear in the new user account and so does the Corel WinDVD 2010 icon.

I have a screenshot of my desktop from before the icons disappeared and from that I can see that about 18 icons disappeared. Furthermore, the default desktop folder doesn't contain any shortcuts either, which probably explains why no icons appear in the new account I created. Shouldn't the default desktop folder contain the shortcuts?

I tried running a microsoft utility that's supposed to fix broken desktop shortcuts but that didn't fix the problem. Are there any other locations that might contain the missing icons other than just the "desktop" and "links" folders? Perhaps within the registry or something?

What can I do to remedy the situation and bring back my icons, other than just recreating the shortcuts manually?

whenever i try to connect to a server on UT3, the game crashes. i've tried changing the compatibility settings, but it didn't work with any of the combinations i tried. i just installed the latest graphics driver from nVidia and the latest game patch from Epic, but neither helped. the only thing i can think of is my memory. i have 1.5GB of DDR SDRAM and when the game crashes, my system monitor gadget shows 1200-1300MB out of 1534MB of memory in use, which leads me to believe i just don't have enough memory to run the game on top of windows 7 (windows takes up about 500-750MB of memory with a few programs running). also, for the first time since i've had this problem, i got an error message giving some explanation and it says something about memory (pictured below). is this a compatibility issue with windows 7 or do i just need more memory? (the max my mobo can take is 2GB, but i might be upgrading my mobo/processor soon).

compatibility settings i've tried:

OS: Windows XP SP2/SP3
Disable visual themes: YES/NO
Disable desktop composition: YES/NO
Disable display scaling on high DPI settings: YES/NO
Run as admin: YES

OS: Windows Vista/SP1/SP2
Disable visual themes: YES/NO

The Pano Head is a rotating platform for a camera that mounts on a tripod and is controlled from your Windows Phone 8 device over Bluetooth. You can use it to take a series of pictures that you can stitch up with Photosynth.

I’ve always wanted to take panoramic pictures with my camera from a tripod, so I decided to make a remote controlled panoramic tripod head that would screw on to any tripod. Using a motor and a shutter control, a series of pictures can be taken. With the use of Photosynth, those pictures can be stitched up to make an interactive 360-degree view. You can also use your Windows Phone 8 as a remote shutter release over a Bluetooth connection. Windows Phone 8 has a Bluetooth API that allows us to program connectivity using TCP/IP style sockets.
This is a popular project in the Arduino world and I wanted to complete it using Gadgeteer hardware and the .NET Micro Framework (NETMF). This project uses the FEZ Cereberus mainboard module, but you should be able to use other Gadgeteer mainboards without any problems.
What is the .NET Gadgeteer platform?

The .NET Gadgeteer platform is an open source toolkit for building small electronic projects using Gadgeteer hardware modules and programmed using the .NET Micro Framework with Visual Studio 2010 or Visual C# Express (2010 edition). The Gadgeteer modules connect together using special cables and very little soldering is required. You typically use a mainboard module, which has the CPU and memory, and then connect various modules (camera, sensors, networking, display, controllers, etc) to accomplish your chosen task.
This part is going to require Visual Studio 2010 C#. Whether the full version or the Express version, it has to be 2010. This is because the Gadgeteer libraries have as of this writing not yet been ported to Visual Studio 2012.
The programming module is easy to work with. Designers are installed into Visual Studio so that you get a visual display of the modules and how they are connected to each other.

You also get full Intellisense for the modules as you code and the best part is that you get to interactively debug through the Visual Studio IDE. In the reference assemblies, you can see a set of assemblies that start with “Microsoft.Spot”. The NETMF came out of the SPOT initiative. SPOT was the underlying technology used in a line of “smartwatches” and selected GPS receivers. The “Spot” assemblies make up the core of the NETMF and the Gadgeteer assemblies provide the “glue” between NETMF and Visual Studio. Also, the GHIElectronics assemblies provide the support for the GHI Gadgeteer modules.
Determining your camera’s remote shutter circuits

You will need a camera that has the ability to use a wired shutter release cable. Most DSLRs and a few point ‘n shoot cameras have a connector for a remote. The camera that I used for this project, a Panasonic Lumix FZ-30, falls in that category. You’ll also need to determine how your camera’s remote is wired. There is a great resource at that lists the circuits and connectors for many popular camera makers.
Most of them use two wires, one to control the focus, the other to trip the shutter. My Lumix uses a single wire and controls the focus and shutter by changing the resistance over the wire. The hardest part here is getting the connector. I bought a generic Lumix wired remote online for a few dollars and then disassembled it to use the wiring and plug for this project.
Hardware list

Part Description Approx Cost FEZ Ceberus Basic Kit This is a Gadgeteer starter kit that comes with the mainboard, plus some modules. You get a FEZ Cerebus mainboard with a 168Mhz 32bit Cortex M4 processor with floating point, 1MB FLASH and 192KB RAM. Also included are a USB module to supply power and provide a USB connection to the PC, a LED module for blinkenlichten support, and a joystick module. $50 Extender Module Used as a breakout board for the camera and servo pins. $5 10 pin Header block Soldered to the extender module to make it a breakout board. $1 4 pin header block Soldered to camera control board to control focus and shutter. $1 Crimp pins Used to make custom jumper wires for easy assembly. $8 Bluetooth Module Provides access to Bluetooth using the SPP serial profile. $40 USB Portable Charger Provides power to the mainboard and servo motor. Needs to have a mini USB connector. $20 Generic Camera Shutter Release cable For around $7, I was able to get a generic shutter release cable for my camera. It provides the cable needed and a verification of the necessary wiring. $10 2N222 NPN transistors Used to allow the device to open and close the focus and shutter connections. Two are needed. $4 Resistors The combination of resistors that tell the camera what action was requested. Three are needed for the Panasonic Lumix camera that I used. $15 Mini circuit board Small circuit board to hold resistors, transistors, and header block. $8 Wood Two pieces of ¼” thick board. The bottom piece is 6” square. The top is 10” by 6”. $5 Lazy Susan Turntable A ball bearing turntable that allows the top part of the base to rotate around the bottom. This allows the top to rotate around the bottom freely. Available from most hardware stores. Get the one that is 6” square. $10 Futaba Servo Parallax (Futaba) Continuous Rotation Servo to rotate the camera a full 360 degrees in either direction $16 Brad Hole Tee Nut Size: 1/4-20 x 5/16. Creates the tripod socket to allow the Pano Head to be mounted to a standard tripod. Place a section of the yardstick over the tee nut to make it flush mounted. $3 Reduction gears Convert the high speed/low torque rotation from the servo, to a higher torque/lower speed on the camera head. I used part # RHA32-26-60. $8 Servo gear Replaces the standard horn on the servo with a gear that will drive the reduction gear. I used a RSA32-2FS-20 from Servo City. $5 Electrical boxes Cheap and easy way to mount the components. $5 yardstick Chopped up as used for the assembly. $1 Thumbscrew Used to mount the camera to the pano head. The size is ¼”-20 x 1/5”. $1 Wires 22 – 26 gauge. $8 Screws, nuts, and bolts Various screws, bolts, washers to mount everything. $10 Liquid electrical tape Used on the soldered wire connections. $6 Total $240 Getting started with the FEZ Cerebus

GHI has a detailed tutorial for getting up and running on the FEZ Cerebus Mainboard. If you are new to the Gadgeteer world, start with the FEZ Cerebus Basic Kit Guide on the Cerebus download page. After installing the compiler and SDK bits, you’ll want to make sure that the board has the correct firmware on it. Detailed instructions on loading the firmware are on the TinyCLR wiki. I recommend using the tutorial to make sure that everything works before moving on.
Once we have the compiler and SDK bits installed along with the tutorial compiles and runs, it’s time to start building this thing.
Building the camera control board

The first part that I assembled was the mini-circuit board for the camera shutter control. I used a single wire to control the focus and the shutter—changing the resistance triggers the camera. So we need to short the circuit between the resistors to get the camera to focus and take a picture. We also want to isolate the circuit from the power coming from the Gadgeteer board. The camera supplies its own power to the circuit and the last thing we want to do is to fry our camera. Accordingly, we’ll use a pair of 2N222 NPN bipolar junction transistors—they are cheap; I bought a bag of 15 from RadioShack for about $3.50—and we’ll use general-purpose input/outputs (GPIO) pins from the Gadgeteer board to toggle the transistors.
This is the circuit that I used for my camera:

The jack is part of the cable that I took from the generic wired remote. Having a wired remote that you can take apart will make this project much easier. You can buy just the jack, but there really isn’t much of a difference in price and it’s easy to match up the wires and resistors after you disassemble the remote.

When the transistors are turned off, the camera shutter circuit flows through all three resistors and the combined resistance is below the threshold that triggers the camera. When we turn on the focus transistor, the combined resistance drops from 41.1k
