OK, I'm not so smart! For the first time in many, many years I deleted a registry key without, of course, first backing it up. Now, for the past several months, every time I start my PC I get the pop-up message from Windows telling me to install an update (which I've done repeatedly). I'm assuming the registry key I deleted is one which registers that this update has been installed. The only part of the key I vaguely remember is "wind" something. I've searched the registry on a friend's computer which runs Win XP (not Pro) and could find nothing with "wind" in the string. Anyone running Win XP Pro SP 3 and has a key with "wind" in its name/string? Help appreciated.

Noting my question has not received any replies I wonder... Was it a stupid question, did I word it incorrectly, or does my stupid deletion of a registry key have nothing to do with why I continually (upon boot/reboot) receive a Windows Update message? I've posted this inquiry on a few other sites and, as here, have never received a reply. Just wondering....
