Could it be you inadvertently created an unnecessary User account?
Second time I?ve had this happen: My XP desktop reverts back to an earlier time. It?s almost like system restore has been activated to restore to another date?but without my permission.
The first time this happened I had changed something in the bios (the startup order of the various hard drives). Once I changed it back, my old desktop reappeared.
The next time happened on a different boot drive but in the same computer. Xp locked up on me during an Xp reinstall going from XP home to XP pro.
When I tried to reboot my drive it performed that long, exhaustive integrity check where it tried to rebuild missing clusters and what not. Once it did this, it successfully booted but my desktop was like it had been several months previous and all work saved during that period was missing.
Although I was able to retrieve most of the missing data by using a recovery program I still would like to use my drive normally. I can only view these missing files with the aid of the recovery program.
By the way, all my system restore files for the last couple months are missing as well so I can?t use that as a means of bringing things back to normal.
