you need to do what i suggested and if you choose option restore to an earlier point/time it should present you with a calendar with some dates highlighted or coulored differently, thes will be earlier restore created points.
facility (start/programs/accessories/system tools/system restore) you'll see the existing restore points marked on a calendar. The restore points aren't backups in the true sense of the word - they're snapshots of the system registry and computer configuration at specific moments, such as when you add new hardware or software, new drivers, or Windows updates for instance. The information that's recorded is limited to certain file types - .exe and .dll. None of your personal data files are included in (or affected by)the restore points.
Restore points are automatically set each time you make changes to software installations, or when you install and unsigned driver, and a restore point is created every 24 hours when the computer is running, or when Windows detects that it's been 24 hours since the last restore point was created. By default restore points are deleted when they're 90 days old to conserve hard drive space. You can also delete restore points yourself.
The system restore points are held in the C:\system volume information folder, in a directory called: _restore
Thank's for that clear and informative response, It could have come direct from the Help files I have just been reading on the new computer behind me. Thank's once again China it makes a change to have some help from forum members on a new Operating System. I am gradually finding my way around it. And to johnnyrocker thank's
