this build is a torrent download? How was it obtained I'm not sure that any of the 7600 builds that are out are truly the same as the RTM. Leaked builds are never trustworthy IMHO. Was this an upgrade or clean install? When the system restarts it starts with those windows open on the taskbar? I have never seen such a thing sorry. Also try to boot into safe mode and see if the problem persists once in safe mode check event viewer (control panel, administrative tools) for anything out of the ordinary .How old is this installation would a re install be a huge step?
