I'm on Windows 7 Home Premium 32-bit with SP1. I have auto-update turned on and have all the latest Windows updates AFAIK.
Every now and then, my system reverts itself to a previous state, including:
- taskbar items
- start menu items
- programs listed in the "Programs and Features" control panel (e.g. successfully uninstalled programs reappear)
- default browser (reverts from Chrome to Firefox)
- contents of long-standing directories (the contents of recently created directories are correct)
I don't care about the cosmetic stuff like wallpaper, but obviously the changes to the file system are a worry.
I've Googled for possible causes, but found nothing useful. There are a number of restore points listed in the System control panel, but I haven't chosen to go back to any of them.
I'm on the verge of reinstalling Windows unless anyone has an idea why this is happening?
Also, I have admin rights on this machine; the other family members do not. AFAIK, I'm the only user affected.
