Disable the UAC feature in Vista
Well, UAC is there for a reason--if your computer got infected by some malware and this malware tried to run an admin tool, the UAC prompt would appear to warn you that someone (you? malware?) is trying to run a tool designed only for administrators. And a UAC prompt when you don't expect it would be a sure sign that something's gotten into your machine's innards.
Still, some users (especially sysadmins) are likely to find these UAC prompts annoying at best, so here's how to disable UAC on your machine:
1. Open Administrative Tools in Control Panel
2. Double-click on System Configuration
3. Click Continue to accept the UAC prompt
4. Select the Tools tab
5. Scroll down and select Disable UAC
6. Click Launch
7. Reboot your machine
Note that you may not be able to disable UAC if Group Policy configured for enforcing UAC on your computers.
Note: This tip is based on a pre-release version of Windows Vista and may not reflect functionality in the final product.
Disable the Windows XP Startup Screen
If you want to see what goes behind the Windows Startup Screen, you have to disable the Windows boot screen.
Right click “My Computer”. Select “Properties”. Select the “Advanced” tab. In the “Startup and Recovery” section, click “Settings”. In the “System Startup” section, click Edit to open the boot.ini file in Notepad. You will see a line that looks similar to the one below:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional"
/fastdetect
To disable the Startup Screen, change the line as below:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional"
/fastdetect /sos.
Note that there is a space between 'fastdetect' and '/sos'.
Close Notepad, click Yes when Notepad asks if you want to save your changes. Exit System Properties. Reboot computer and the Startup Screen will be gone.
