Colin Thanks for the advice. Alas, I've tried all that already :-( - but learned a few more thnigs alongh the way. And Windows_key-PauseBreak was new to me - I've always done it the hard way. Useful, thanks. Isaac - Yes, I'm using CMD.EXE. Interestingly, I just tried commamd .com (a long ago old friend) as as you say, it used to have SOME functionality in XP, and now it opens a WIndow / DOS box but does utterly nothing except allow you you close it by mouse click. Restore points - Comodo has allegedly been making these on and off of late BUT on looking I have but 2 and only a few days old. I do save full registry dumps occasionally and if needs must will try reverting to an earlier one. Russell I'll ask another question in another email. Russell.
