Hi Catalin I also feel that the rollback sequence was the cause of the corruptions but did not realize this was MS s/w. I have now recovered by performing a restore from a disc backup taken in December (and copied across user files that have changed since that time). I will perform system backups more frequently from now…

Thanks for quick response. I replaced the file (system) from a backup of the same system disc made in December 2008. Nothing should have changed other than Windows auto updates. I have tried rebooting with Last Known Good Working Configuration selected then Safe boot_s, in fact all options available but the problem…
