Recover Batch Files Using Cmd.exe

Question

I installed gvim on windows vista and am very happy to edit EVERYTHING with it. I linked the .bat files to gvim and now I can not get the bat files to run ... oops !! Can someone explain how to overwrite .bat files with cmd.exe so that double-clicking on them makes them just start?

EDIT: I followed Jim's next tip by deleting the registry key. After rebooting, bat files still open in my text editor. I double-checked my registry and the key was recreated. Then I found that the text editor was installed in Control Panel> Default Programs> Link File Type. I modified the bat files to open with Cmd.exe, but Cmd.exe simply opens without running a batch file. I assume the problem is still in the registry.

Answer 1

This has reg file downloads for all default file extensions. Just download bat and run it, this should return all associations back to default.

Note. Although he says that only for Win7 is also good for the future.

Answer 2

Using regedit.exe, find the key

 .bat 

under

 HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts 

and delete it.

EDIT: Also, this one

Windows Registry Editor version 5.00

[HKEY_CLASSES_ROOT.bat] @ = "Batfile"

[HKEY_CLASSES_ROOT.bat \ PersistentHandler] @ = "{5e941d80-bf96-11cd-b579-08002b30bfeb}"

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

I no longer have a problem with this, but still looked above :)!

Answer 3

Merging a .reg file or editing the registry manually is the most reliable option, but perhaps you could just run assoc .bat= from the admin command line.

If none of them work, it is possible that Windows is hiding file extensions from you, and this is actually a .bat.txt file. Uncheck the option "Hide extensions for known file types" in "Explorer Options" (formerly known as "Folder Options") and rename the file.
