Vista ultimate - Windows Explorer crashes every time I run control panel / uninstall a program

Every time I try open uninstall a program from control panel, explorer crashes, and restarts.
So far I haven't found anything that looks out of the ordinary.  

Event Viewer Application log looks like this:

Faulting application Explorer.exe, version 6.0.6002.18005, time stamp 0x49e01da5, faulting module appwiz.cpl, version 6.0.6002.18005, time stamp 0x49e036fa, exception code 0xc000001d, fault offset 0x000231f1, process id 0x1f70, application start time 0x01ca91e7110a9b05.

I don't use this Notebook all that often anymore, so I have no idea when this started.

Just something i read somewhere a while back that it could be caused by Internet Explorer. Try completely removing and reinstalling Internet Explorer. Follow http://support.microsoft.com/kb/318378 for steps on reinstalling. Worth a try but im not sure why IE would cause the Control Panel to crash.

Are you running 64bit?

For start, you should install all available windows updates.

If You have all the latest updates installed, and it still doesn't work, you should maybe look at this:

Hi, Its a problem with 3rd party(Non Windows) control panel applet that sits under C:\Windows\System32.

So whenever you try to open control panel, the 3rd party control panel applet will also try to load on your system. If the 3rd party control panel applet uses any of the system files which is normally used by default windows control panel applet, conflict occurs and it causes the explorer to crash.

1. Go to C:\Windows\System32 and search for the control panel applets using the search option with the cearch criteria - *.cpl and hit Enter.
2. From the search results, look for the names of the control panel applets. The best way is to perform a divide & conquer methodology.

Try renaming any control panel applet with suffix - .old and check for the problem.
If problem is fixed then thats the control panel applet which is causing the problem. If not, rename the control panel applet back to its original name i.e remove the suffix .old from the file name.,

I know that its time consuming and also you might feel as stupidity but each try will let you closer to the issue.
To make things simpler, if you another vista computer nearby, search for the control panel applets on the other computer and compare with the faulty system. Try renaming the mismatch applets and check for the issue.

IF you still have problems after trying these above steps, check for the issue in safe mode & Clean boot.

All the best
you can try the uninstaller cleanup from MS : http://support.microsoft.com/kb/290301

Hi All,

thanks for your suggestions, nothing helped.

I managed to run a third party uninstaller, which also gave an error - but remained open - and still allowed me to uninstall the programs I needed removed.

This whole effort was to enable be to run an upgrade, so while the error still exists, I am going to upgrade and see where that takes me,
