The blue screen didn't say anything, it just sat there taunting me for about 6/7 seconds
Well anyway i tried the safe mode approach as you suggested. No blue screen or crash however the programs and features have still lost the uninstall/change/remove option. There are a few exception this time though, adobe photoshop, firefox and ISScript all have the ability to uninstall. The programs that are missing from the list there are still available in the start bar and still work, they just don't seem to want to show themselves at programs and features.
It's an overall improvement anyway, thanks! Though any other ideas which will set it all right would be good :D
Thank you for your help so far, kay
