Windows Vista Explore Context Crashes

For weeks now I am gettting File Explorer crashes and I have tried Microsoft Knowledge base and sent numerous postings of the crashes with no replies as to what is causing it, from the event viewer I have extracted the most common cause as follows:

I appears that the crashes are caused by a "faulting module ContextHandler.dll_unloaded " so I have used ShellExView in the hope of tracking down the offending context handler but (including windows ones) there are over 300 in the list it is hard to find which one is causing it, I have disabled a few but then explore still crashed.

I could go a few hours using explorer (or even days) then I will get 2 or 3 in an evening.

I have gone as far as my knowledge allows me to, can anybody help?

 

Explorer crashes

Had similar problem and the best solution for me was to reload the operating system.
Do a new installation not an upgrade an upgrade will reinstall the same problem
then you can install explorer 7.

 

Thanks for quick reply, and yes one of the programs listed from your link was Ashampoo WinOptimizer, and the file is in it's program folder so I am going to uninstall the program and hopefully it may stop the crashes.

If works okay I will reinstall after a week and see if it returns and contact the company if the error comes back.

 

As mentioned before uninstalled Ashampoo to cure Windows Explorer crashes, but the next evening it happend again this time the dll recorded was SSCtxMnu.dll and this one belongs to Webroots Spysweeper and it is the latest version. I have not uninstalled it at the moment just stopped it running at start up.

Both of the programs are reported to be Vista friendly, so what is going on here? Soon I will have nothing installed. I have had Vista since its launch and I do not remember explorer crashing before and I certainly had Spysweeper installed.
