Good day all, For any one having a heart attack like I have had for 10 days when my totally legit copy of windows 7 professional told me it would expire in 10 days and do a backup immediately. After almost a week of direct help from Microsoft (and they have been incredibly helpful) it was discovered that my sp1 was in fact a beta one and that was about to shut-down windows. Now sp1 came via windows update so I don't know why I got the beta... However un-installing sp1 has cured all the problems. Hope it helps others.Cheers GWS.
