So I have decided to test out Windows 7 and have downloaded the 64 bit RC version and done the updates.

Problem I am having is with the pop up that precedes starting some legacy 32 bit application like CPUZ etc.

User Account Control

Publisher Unknown

So I see that I can turn off of this paranoia globally but I can’t figure how you do it selectively inasmuch as I would like to turn it off for particular application once they have been run for the first time…

Any ideas please?

Seems to me that Windows 7 needs and “Allow Always” button on the UAC pop up!

Many thanks IMK

I invented Windows 7

Describes an issue in which you cannot change User Account Control (UAC) settings on Windows 7 after you install Office 97. Provides a resolution.


One of the highly criticized features in Windows Vista is the User Account Control(UAC) which prompts up a dialog box seeking users' permission to continue or stop whenever a system-level change is made. The problem with Vista is that even the default user account which is created during the install, who is a protected administrator (unlike in XP where the user is an Administrator), could not bypass the UAC until its tweaked. This created lots of criticism and the feature which was built to make Vista secure became the most hated feature amongst users. Of course, this was a drastic change for Microsoft and as well as end users who were very much inclined to a single user account (till Windows XP) who is an Administrator.

One of the major complaints was that the UAC involved more clicks to execute a program when such system-level change occurred. And the other - there were only two options provided by Microsoft in Vista's Control Panel - either Turn On UAC or Turn Off UAC. Users did not have much control over the behaviour of UAC notifications.

How far has this changed in Windows 7?

When the E7 Team blogged about UAC, it was clear that Microsoft was taking the user feedback seriously about the issues and problems they currently face using UAC in Vista.

In Windows 7, Microsoft has given options for the users to select their 'comfort level' in UAC notifications and also improved the user interface by providing more relevant and additional information. The default user account created during the installation in Windows 7 is still a protected administrator but with a different UAC setting:

Yes, the default user would be prompted only when programs try to make changes but not the user himself.

The UAC icon has gone for a change and it looks much better now than in Vista:

Windows 7 UAC Settings has a Slider to change your 'comfort-level' with the notifications. You can choose one from the following four options:

Below is a screenshot of the UAC prompt when you run an application form a known publisher:

Below is a screenshot of the UAC prompt when you run an application from an unknown publisher:

Since many software programs did not support UAC when it was first introduced in Windows Vista, the applications failed and created lots of issues, which reflected in a bad user experience. As many applications are built with the support of UAC now, it is a seamless experience in Windows 7.

You can see that the user can go directly to the UAC settings from the prompt to change how these notifications appear if the user is not happy about these notifications.

Overall, the UAC experience is much improved in Windows 7 than in Windows Vista. The number of clicks (by default) is drastically reduced in Windows 7 when compared to Windows Vista. The ultimate goal of the UAC is to provide user the control over what changes can happen to the system and not to annoy users with more number of prompts.


Windows 7 default user account control worries experts. Corporate IT departments should be pleased with new security measures in Windows 7, but consumers are still at risk of getting hit by malware despite changes in the User Account Control (UAC) feature designed to help people be smarter when using applications, security experts say. Probably the most talked about security change in Windows 7, scheduled for public release on Thursday, are modifications to the UAC, which was introduced in Vista. The UAC was designed to prevent unauthorizedexecution of code by displaying a pop-up warning every time a change was being made to the system, whether by the operating system or a third-party application. Vista users complained that they were bombarded with the warnings and security experts speculated that as a result, many people were just ignoring them or turning them off.

With Windows 7, users can choose how often they want to be notified and the default is set to notify only when a third-party application is making a change, as well as when a change is being made to the UAC itself. However, an attacker could use code injection and exploit several components in Windows 7 that auto-elevate to bypass UAC and get
full access to the machine, experts have warned. A Sophos white paper from September says: “Another issue with thesedefault (UAC) settings is that malware could bypass the system by injecting itself into a trusted application and running from there. Indeed, some malware has been observed spoofing UAC-style prompts to obtain user permission to operate unimpeded.”

Taking charge of Windows' User Account Control

By Fred Langa

Windows can be a terrible nag, and in Vista and Windows 7 it can be most annoying when popping up its User Account Control (UAC) security prompts.

UAC implementation proved clumsy in Vista, and it can still annoy in Win7 — but there are ways to make it less so.The full text of this column is posted at (paid content, opens in a new window/tab).

Columnists typically cannot reply to comments here, but do incorporate the best tips into future columns.

I have Win7 professional pc with three partitions c:,d:,e:. I have two user accounts: Administrator and Admin.
When i log into Administrator account, my saved files don't show up on the desktop although i can access those files manually through the path c:>users>Administrator>desktop. I am also not able to save any file on the desktop except in d: or e:.
I tried to change UAC settings but the option "Change User account control setting" doesn't open up. Also I am not able to edit my Administrator account.
I opened command prompt to see the current user account at the prompt, it shows as c:USERSTEMP.PC1>.
I think i am logged into "TEMP" user account instead of logging into "Administrator" account.
Kindly help me find the solution, I will be very thankful to you.

(Edited by agnostic on 06-Mar-07 10:48. )On page 104 of the Vista for Dummies book, there is a procedure for disabling user account control by accessing secpol.msc.

I try this, and secpol.msc cannot be found.

Is there another process available to achieve the same thing?


Subsequent to posting the above, I found a freeware program - TweakUAC.exe from which seems to achieve the task. Hopefully, it is not secretly malicious.

I'm using Windows 7 64-bit Home Premium

As required to use administrator privilege from standard user account, enter said password for the Admin account; UAC doesn't launch the program it just stalls or leaves the Start menu unusable.

I have to use the windows run prompt to logoff, other operations work just fine.

When you try to open the “Check Disk” dialog box on systems where User Account Control (UAC) is enabled, the "Check Disk" dialog box may randomly stop responding for a short period of time after being opened. The user is unable to move the dialog box or...


When I start certain programs then sometimes an "User account control" UAC popup appears asking me if I really want to allow this program to start and possibly to make changes to this computer.

How can I suppress this popup permanently FOR THIS progam (but keep it in general for all new programs) ?


How to use the Task Manager in Windows 7 Professional

This is VERY troublesome. There are numerous comments and suggestions in various forums by frustrated users unable successfully to fight their way through the myriad of options that do not work seamlessly. What worked so easily under XP Professional seems hopelessly complex and difficult under Windows 7 Professional. However, after much experimentation I have finally got a Windows 7 machine to do what it is supposed to. I'd like to share my findings with others in order to help (hopefully) reduce their time finding the solution...

I am running a machine to collect data from a weather station and marine thermal monitoring equipment every few minutes using RF links with an Arduino board controlling transmitter and receiver. The data arrives in the computer via a serial/usb dongle on the back of the radio. Every 20 minutes the incoming data is dumped into a file, the file is closed and then a new file opened for the next load of data. At the end of each 24 hour cycle, a suite of 11 programs are run in sequence to massage all the daily files, reformat them, carry out analysis at various levels, rewrite some html files, produce graphs, and then the final task is to upload revised html files and images to a server for a web page. The system is designed to run 24 hours a day and 365 days a year without interruption.

There are at least three things which do interrupt the machine, and it is therefore advisable to disable these functions. They are:

1: Power outages. I live in an area where there are frequent outages. Usually these only last a few minutes, but sometimes they last much longer. It is essential to have an UPS to provide power in these cases. I use a 1000 VA/600 watt Dynamix, which in theory (specifications) could provide up to 100 minutes backup (unlikely).

2: Disable automatic windows updates, which occasionally reboots the system without permission from the user.
Control panel
Windows update
Change Settings
Never Check for updates

3: Disable Power saving protocol, such as sleep, monitor off, etc.
Control panel
Power Options
(choose) High Performance
Change Plan settings
- On Battery Plugged in
Dim 5 minutes Never
Display Off 10 minutes Never
Sleep computer Never Never

4: Turn off the display when the PC is running to save the screen from pixel damage.

5: Most of the problems with obtaining successful use of the Task Scheduler in Windows 7 arise from the UAC (User Account Control) being a lot more strict than in XP-Professional, and in particular security relating to blank passwords. In XP-Pro it is possible to undo this password requirement, which makes things a lot simpler. The method for doing this in Windows-7 is similar to XP-Pro, and this is how it is done.
type regedit (click OK)
click Yes
Open up the + for HKEY_LOCAL_MACHINE
Open up the + for System
Open up the + for Current control set
Open up the + for Control
Click Lsa
Double click LimitBlankPasswordUse
change the 1 to 0 (Hex)

6: Unfortunately, unlike with XP-Pro, undoing the blank password requirement is not the end of the matter with Windows 7 passwords. It is necessary to provide a password for each task in the task scheduler to function. This has a number of unfortunate implications, such as restricting access within your home network. However, it must be done. Here is how:
Control Panel
user account
Create a password for your account
***** (enter twice)
NB: One can also remove your password later which is kind of Windows 7.

7: Under XP-Pro when a program, say TIDES.EXE, was entered into the task scheduler, the scheduler was clever enough to understand that any input files that were required or output files produced would reside in the same folder as TIDES.EXE unless the code inside the EXE file had specified otherwise. Not so, for Windows-7. It has been necessary for me to revise all my pascal code to specify full pathnames for every file opened or closed by the software, and recompile the code. It is also necessary fully to specify pathnames for any BAT files that you want the task scheduler to run. For example, a typical BAT file will have to look like this:
d:seawaternguplot.exe d:seawatersensor5.cfg
and inside the cfg file all input and output files will also require full pathnames. This seems extremely stupid.

8: Gaining adequate privilege for a task is the next problem. With windows explorer, navigate to the EXE file you want to run by autopilot, and right click on it, and then click on properties.
click edit
One at a time allow "Full control" for each of
Authenticated users

9:Finally, we have reached the point where one can install a task in the Task Scheduler.
Control Panel
Administrative tools
Task scheduler
Create a basic task
Name: enter something, eg : "Update Tidal Predictions", and click Next
Select Trigger daily, and click Next
Select a starting date, the regular time, and 1 day, and click Next
Start a program, and click Next
Browse to the exe file, eg D:SEAWATERTIDES.EXE, and click Open

10: Oh, No, not quite finished yet. It still wont run. You need now to:
Highlight your task "Update Tidal Predictions" and click Properties
Select Run whether user is logged on or not
Select Run with highest privileges
Select Configure for Windows 7
Enter password *****
Now at last you really are finished. If you have several tasks (I have 11, spaced every 3 minutes at 1am every day), you need to repeat all of this for each task.

Good luck

User Account Control (UAC) was probably the first new feature of Windows Vista that most users encountered, and received considerable attention when the OS was released. UAC gives a way for users to act as computer administrators just for administrator tasks. This is important to only allow software that requires elevated rights to run with such powerful (and potentially dangerous) rights. Over time, UAC prompts have diminished, especially with the release of Windows 7. But it's clear malware authors really hate UAC.

A simple change made into Windows 7’s registry can cause the operating system to cut access for end users to the settings of the User Account Control feature. According to the Redmond company, the Office 97 has been identified as the source of the problem. Microsoft explains that the issue only occurs in scenarios in which end users attempt to install Office 97. It is the very installation of Office 97 that is responsible for the registry change which cuts off access to the settings of UAC in Windows 7.
In the Windows 7 "System and Security" control panel category, the Action Center lets you change User Account Control (UAC) settings. In the User Account Control Settings dialog box, you move the slide bar control for notifications, and then you click the OK button. In this scenario, the dialog box does not close, and no change is made. When the mouse pointer is positioned on the OK button, and you press ENTER, the dialog box still does not close, and no change is made,” Microsoft revealed.

Microsoft doesn’t offer a hotfix or an update designed to resolve this specific issue as of yet. However, the Redmond company does have a manual fix in place. Users will be required to essentially mend the problems created with the installation of Office 97 on top of Windows 7. Essentially, users need to put together a file that will modify the Windows 7 registry. For this, they will need nothing more than Notepad. They will need to create a file with the name UAC.reg and place it on the desktop. Next, they will have to copy and paste the following text in the UAC.reg file, save it and close the text editor.

The title says it all. Here's the article:

How can one discover whether a display like this

is genuinely from MS, rather than from malware phishing for the Admin password?

Though MS says (below) this blue+yellow UAC shield verifies MS is the publisher, clearly the presence of the shield does not guarantee MS is the publisher.


What is User Account Control?

When your permission or password is needed to complete a task, UAC will
notify you with one of four different types of dialog boxes. The table below
describes the different types of dialog boxes used to notify you and
guidance on how to respond to them.

Icon [blue+yellow shield]

A setting or feature that is part of Windows needs your permission to start.

This item has a valid digital signature that verifies that Microsoft is the
publisher of this item. If you get this type of dialog box, it's usually
safe to continue. If you are unsure, check the name of the program or
function to decide if it’s something you want to run.


Has anyone else had problems installing Silver Light update version 4.0.50917.0 from Windows Update? I'm running Win 7 Pro. 64 bit, AMD Phenom 9950 Quad-Core Processor. This update failed, and Silver Light no longer worked (Netflix wouldn't play movies, message said it needed Silver Light).

Microsoft support : completely uninstall Silver Light with Windows Installer Cleanup Utility. Reinstall Silver Light. It didn't work, error code 1603 when trying to reinstall. I then found that I could no longer install any program. At this point I'm tired of fooling with it and decided on a clean reinstall of Win 7. That fixed everything and when the Silver Light update appeared at Windows Update I ignored it...I'm still ignoring it.

Meanwhile, MS support has sent me a page of instructions that I will paste at the end. I replied that I had done a clean install and Silver Light was working again (the update had not yet popped up on my Windows Update).

My husband, who has an almost identical system to mine, tried to do the Silver Light update and experienced the same problem. MS support sent him the same suggestions, which he tried, but with no luck. He is still emailing back and forth with MS trying to resolve the issue.

Any ideas why we've had this problem? Anyone else having a problem with the download?


Microsoft's 2nd try at fixing the problem:

Based on current situation, the most likely cause is that the current user account does not have the correct permissions to access related folders and registry keys. At this point, I suggest we first try the steps below to reset the default permission on those folders and registry keys, which will be accessed when installing Silverlight:

1. Please download the subinacl.msi file from the following link and save the installation patch on the Desktop:

2. Please go to the Desktop and double click the downloaded file.

3. Please select the C:WindowsSystem32 folder as the Destination Folder during the installation. Later we will use this tool to reset the permission settings on the current machine.

Note: If UAC (User Account Control) window is prompted for permission to continue, please click "Continue".

4. Click "Start". In the Start Search bar, type: "notepad" (without quotes) and press Enter.

5. Copy the following commands and then paste them into the opened Notepad window:

@echo off

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f

subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f

subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f

subinacl /subdirectories %SystemDrive% /grant=administrators=f

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f

subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f

subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f

subinacl /subdirectories %SystemDrive% /grant=system=f

@Echo =========================

@Echo Finished.

@Echo =========================


6. After pasting the above commands, please close the Notepad window. Choose Save when you are prompted to save the file. Type "reset.bat" as the file name and choose Desktop from the left panel as the save location.

7. Refer to the Desktop and right click the reset.bat file, then choose "Run as administrator."

8. You will see a DOS-like window processing.

NOTE: It may take several minutes. When it is finished, you will be prompted with the message: "Finished, press any key to continue".

9. Please restart the computer and install Silverlight again from to the following website:

Does Microsoft Silverlight install properly? If not, please follow the steps below to collect Windows Installer log:

1. Click Start Button, type "cmd" in the search bar. The CMD icon will appear in the Start Menu.

2. Right click the CMD icon and click "Run as administrator".

3. In the popup window, copy and paste the following command then press Enter:

REG ADD HKLMSOFTWAREPoliciesMicrosoftWindowsInstaller /v Logging /t REG_SZ /d voicewarmup /f

4. Click OK or press Enter to run this command.

5. Restart the computer.

6. Try to install Microsoft Silverlight again.

7. If it fails, click Start, type "%temp%" (without quotation marks) in the Search Bar and press Enter.

8. Please send all "XXXXXMSI.log" files to me

trying to install a software for music of the MAGIX softwarehouse ,the installation stops after a while and a windows appears saying: impossible opening the file C:windowstempmgxoservicesindex_0410.htm.
The software house service gave me the following instruction:disable UAC(user account control), remove antivirus,go to msconfig and disable all the system setup in the start menu,restart the PC and install the program.
Result: same as before
some tricks will be very very welcome
