In my windows XP installation, the system harddrive constantly (every 3 sec about) writes to the drive. This ofcourse makes alot of unessessary noise. Nothing special is running according to the taskmanager (system waitprocess is using 99% cpu). When I check what is accessing the harddrive at these intervals (using sysinternals FileMON)...it is the files NTUSER.DAT and NTUSER.DAT.LOG that is cousing these constant harddrive-writing. Why is it doing this, and how do I fix it? Extremly annoying.
