I now have further information.
Error message "Unexpectred error on Property Page, Volume Shadow Copy Servide used by System restore not working. 0x81000202"
I have an Advent 4211 netbook running Windows 7 and it has just started acting oddly.
1. I cannot access System restore
2. I am having trouble getting connected to my home Network when a few days ago all was well.
I did do a system cleanup using Spotmau.
Is there anyway I can reset the system back to a default position, effectively undoing any changes i have made.
bear in mind System restore is not working!
