I asked one of our PC gurus, and he said try the "CPL File Association Fix" link at this site: <p><a href="http://www.dougknox.com/xp/file_assoc.htm">File Association Fixes</a> <p>-dan

Thanks Dan, <p>I should have mentioned that this PC is running Win 98. <p>Dave

David, <p>If it helps, he says he's sure it's a file association problem, so you might use the XP entries as a guide for the file types to look for, and try to fix them manually. Maybe that'll at least narrow it down for you. <p>-dan

Thanks, <p>I shall certainly try. <p>Dave

Maybe you can try to re install the *.CPL file from one of the CAB file from Win98 installer. I've just help my friends shops to recover missing Control Panel icon. You certainly find TweakUI usefull.

Thank you. <p>TweakUI is useless in this case, because TweakUI runs from the control panel, and all control panel apps have been rendered inoperative. <p><big>further info</big> <p>After more research, I discovered that the problem was a particularly nasty virus called the <u>MSUpdate Hijack</u>, or the <u>Cool Web Search worm</u>. <p>A rogue Argentinian file called MSUpdate was placed in my startup and all executables run from it. Removing the file (MSUpdate.exe) will render all executables inoperative. <p>I hope to get a solution from McAfee this week. <p>Dave

I am trying to recover operations on a PC that had a virus. <p>I managed to get everything up and going, but then discovered that all the applications in the Control Panel had ceased functioning. <p>I think that there are settings in the registry that can cure this, but that's about all I know. <p>Any help and assistance in this matter would be greatly appreciated. <p>Dave
