Much has been said about the new User Account Control (UAC) system that will be shipping with WIndows Vista. UAC is supposed to usher in a new era of security for Windows by preventing, for example, unauthorized programs from making changes to system files. Vista beta-testers are finding it to be a bit of a nuisance, however, with UAC prompts popping up for all manner of seemily-innocent operations. Over at ZDNet, Ed Bott explains the reason for these prompts and how to work around them. It's an interesting look at how Microsoft is dealing with security in Vista, and also a preview of some of the trouble less-technical users are going to be having come next year.
