Method #1 - Using MSCONFIG
1. Launch MSCONFIG by from the Run menu.
2. Click on the Tools tab. Scroll down till you find "Disable UAP" (this should probably change to UAC in next Vista beta builds and in the RTM version). Click on that line.
3. Press the Launch button.
4. A CMD window will open. When the command is done, you can close the window.
5. Close MSCONFIG. You need to reboot the computer for changes to apply.
Note that you can re-enable UAC by selecting the "Enable UAP" line and then clicking on the Launch button.
Method #2 - Using Regedit
1. Open Registry Editor.
2. In Registry Editor, navigate to the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System
3. Locate the following value (DWORD):
EnableLUA
and give it a value of 0.
Note: As always, before making changes to your registry you should always make sure you have a valid backup. In cases where you're supposed to delete or modify keys or values from the registry it is possible to first export that key or value(s) to a .REG file before performing the changes.
4. Close Registry Editor. You need to reboot the computer for changes to apply.
In order to re-enable UAC just change the above value to 1.
There are more ways like using the Group policy or the control panel, but I fee the methods above are easier.
