Have you recently noticed that when you right click on a Batch File there are no Edit, Open or Print commands on your context menu?
This happened to me and was driving me nuts. I contacted Microsoft Technical Support E-Mail, and they sent me a RegFile to correct this which did not work. I replied and they promptly sent me another much more detailed one, which also did not work. However the second one, which was the complete BatFile Key of HKCR, gave me enough info to find and fix the problem.
It seems that the CleanSweep portion of Norton System Works 2001 Professional erroneously adds a SubKey and Data to the BatFile Key. When I deleted this SubKey all the functionality was returned to my context menu. I think System Works is a great program, so I have sent the info off to Symantec so they can fix it in future versions. If you have this problem, here is the SubKey to delete. (Of course all those warnings you have heard about backing up the registry before altering it apply.)
Why didn't the correct RegFile from Microsoft solve my problem? It seems that when you run a RegFile it only adds its info into your registry. It does not delete any keys not listed automatically. Since ContextMenuHandler is not a default SubKey of BatFile it was not affected because it was not listed in the RegFile from Microsoft.
Hope this little tip helps.
