Windows 7 User Account Control displays less warning than UAC in Vista, and lets you customize UAC according to your need and preference between security and a less annoying desktop experience. UAC prompts in Windows 7 are not as much as in Vista as very few programs require elevation, and Administrator can adjust these UAC prompts.
Go to Start > Control Panel > User Accounts > Change User Account Control Settings
Here you can select when to notify or bring the UAC prompt. There are 4 levels of security which includes: - - Always Notify
- Notify me only when programs try to make changes to my computer
- Notify me only when programs try to make changes to my computer (do not dim my desktop)
- Never Notify
Select them according to your balance between security and desktop experience and adjust the level of UAC prompt. Any change to the level of the UAC will prompt for confirmation.
