Live With User Account Control

One area where some people might want to see the Windows Security Center turn red is User Account Control (UAC), perhaps the most controversial security feature within Windows Vista. Designed to keep rogue remote software from automatically installing (among other things), UAC has a tendency to thwart legitimate software installations by interrupting the process several times with useless messages. In Windows 7 you'll be able to set UAC to the level you want. Until then, you do have some options.

One is to disable UAC. I would caution against that, since UAC is meant to warn you of potential danger. Instead, install , a free utility that offers the ability to turn UAC on or off as well as an intermediate "quiet" mode that keeps UAC on but suppresses administration elevation prompts. With TweakUAC in quiet mode, UAC will appear to be off to those running as administrator accounts, while people with standard user accounts will still be prompted.
