I've got a workstation on my network running XP Professional. It's got an 80 GB drive, and Windows is bloated to 45 GB. For comparison, on my own workstation Windows is almost 8 GB.
I've been looking at folder sizes, including hidden folders, and nothing is jumping out at me as the culprit. IE cache has been cleared. Any suggestions as to what could be causing so much space to be lost to the OS?
