Hi,

I have screwed up my windows xp system by accidently mapping an executable file to always open in wordpad. Now all my applications open in word pad, and I can't start anything (wordpad excepted). Can anybody tell me what I need to do to reverse this mapping? I'm guessing there's an entry somewhere in the registry that I need to change, but I have no idea where.

Thanks,
Geoff.

Open a Command prompt Window (Start button-->Run-->cmd) and type:

copy %windir%\regedit.exe %windir%\regedit.com
regedit.com

The registry opens... Go to the key:

[HKEY_CLASSES_ROOT\exefile\shell\open\command]

and in te right pane make sure the value data of (Default) be:

"%1" %* (quotes percent one quotes space percent asterisk)

Close the registry and make a test...

I just checked that entry, and it's already set as you suggested. Here's an export of the key:

[HKEY_CLASSES_ROOT\exefile\shell\open\command]
@="\"%1\" %*"

Any more suggestions?

And what's on

[HKEY_CLASSES_ROOT\.exe]

So here's my entry for .exe:

[HKEY_CLASSES_ROOT\.exe]
@="exefile"
"Content Type"="application/x-msdownload"
"ZAMailSafeExt"="zl9"

[HKEY_CLASSES_ROOT\.exe\PersistentHandler]
@="{098f2470-bae0-11cd-b579-08002b30bfeb}"

So following the {098f...} number in the registry, shows that it's a common persistent handler, but has this definition:

[HKEY_CLASSES_ROOT\CLSID\{098f2470-bae0-11cd-b579-08002b30bfeb}]
@="Null persistent handler"

[HKEY_CLASSES_ROOT\CLSID\{098f2470-bae0-11cd-b579-08002b30bfeb}\PersistentAddinsRegistered]

[HKEY_CLASSES_ROOT\CLSID\{098f2470-bae0-11cd-b579-08002b30bfeb}\PersistentAddinsRegistered\{89BCB740-6119-101A-BCB7-00DD010655AF}]
@="{c3278e90-bea7-11cd-b579-08002b30bfeb}"

So I followed the new {c3278...} number and get:

[HKEY_CLASSES_ROOT\CLSID\{c3278e90-bea7-11cd-b579-08002b30bfeb}]
@="Null filter"

[HKEY_CLASSES_ROOT\CLSID\{c3278e90-bea7-11cd-b579-08002b30bfeb}\InprocServer32]
@="query.dll"
"ThreadingModel"="Both"


And that seems to be a dead end. :(
