Disable User Account Control (UAC) the Easy Way on Win 7 or Vista
Windows Vista/Windows 7 has the built-in ability to automatically reduce the potential of security breaches in the system. It does that by automatically enabling a feature called User Account Control (or UAC for short). The UAC forces users that are part of the local administrators group to run like they were regular users with no administrative privileges.
Although UAC clearly improves the security on Windows Vista/Windows 7, under some scenarios you might want to disable it, for example when performing ERPro/HRPro workstation installation.
Note: Disabling UAC will lead to a less secure system, so be warned.
Disable UAC on Windows Vista
Open up Control Panel, select User Accounts or User Accounts and Family Safety (depended on your Vista Edition).
Click on the Turn User Account Control on or off link:
On the next screen you should uncheck the box for “Use User Account Control (UAC)”, and then click on the OK button.
You’ll need to restart your computer before the changes take effect, but you should be all done with annoying prompts.
Disable UAC on Windows 7
Windows 7 makes it much easier to deal with UAC settings, and in fact you don’t have to completely disable UAC if you don’t want to. Just type UAC into the start menu or Control Panel search box.
You can simply drag the slider up or down, depending on how often you want to be alerted.
If you drag it all the way down to the bottom, you’ll have disabled it entirely.
