disable System Restore. Right click My Computer > left click Properties > System Restore tab > place a check mark beside "Turn off system restore on all drives" > Apply > OK. Then turn system restore back on.
Hope this helps.
When trying to create a restore point the following dialog box is produced. '' System Restore is not able to create a restore point. Please restart the computer, and then run System Restore again''. And yoy get the message again after rebooting. Also you cannot retore from a restore point, the calendar only shows the current month.
