LowWaterMark note: This discussion of Vista UAC was split off from a NOD32 thread. When you create a security feature that's so annnoying that it's unusable then all the effort goes down the drain, no matter how good the intent might have been. This is the case w/ UAC in Vista, this has been the case with IE "secure mode" on server versions of Windows. Annoying to death and/or unusable. Regardless, Norton User Account Control tool would be a good start for MS when giving second thoughts to a usable UAC implementation.
