verclsid.exe, courtesy of Microsoft Corporation, delivered by auto update as security update MS06-015 to a PC near you about now, may well be the cause of the most recent very bad problems your PC has been having if its being having really bad problems recently. [ :-) ]. It destroyed the ability to function in any sane manner of a Windows 2000 Professional PC on my LAN a few days ago and did the same on a Windows XP Home machine 2 days later. The file installs a process of the same name which cannot be stopped by trivial means. It's intended to stop certain programs being run by people who ought not to be running them but in the process seems to variably knobble other programs in some systems. Symptoms are you may be unable on a variable basis to run OE, IE, start button via keyboard (but by mouse click OK)(Olin filter), start button by any means, various other tasks variably. A quick temporary fix is to rename verclsid.exe to something else. MS will no doubt reinstall it again for you shortly. found in \your_windows_path\system32\verclsid.exe What it's meant to do http://www.microsoft.com/technet/security/bulletin/ms06-015.mspx What MS suggest you try if it addles your PC's brain http://support.microsoft.com/kb/918165 Russell McMahon -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
