Windows 7 - Microsoft: Malware can disable UAC in Windows 7 "by design"

A month has barely passed since the public beta debut of Windows 7 and we have our first horror story.

UAC (user account control) was the major gripe with Windows Vista which annoyed most tech savvy users and confused ordinary consumers. Microsoft has changed the behavior in Windows 7, lowering the requirement for user interaction when changing system settings. The apparent downside to this is, according to reports, the way Microsoft has changed the behavior makes it extremely easy for malware authors to write code to disable UAC without user intervention.
