I seem to have done something that screwed up my Win 7 RC slightly, but I have no idea what it was. All of a sudden, the icons on the desktop (more precisely, icons for links, not actual files) change their colors at the last stage of the boot up. What I mean is that after I type in my password the desktop appears with all icons shown correctly. But then, as the machine finishes booting up - i.e. starts all the sidebar and anti-virus and other apps - at the last second the icons lose their colors. Sometimes later on they regain them - but again, I have no idea what causes it. If anyone has seen something similar, I would be grateful for a tip.
