Reassociate Batch Files with Cmd.exe
Solution 1
This has the reg file downloads for all the default file extensions. Just download the bat one and run it, this should restore all the associations back to default.

Note: Although it says it is only for Win7 it should be fine for vista as well.

Solution 2
Using regedit.exe, look for the key
.bat
under
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts
and delete it.
EDIT: Also, this
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\" %*"
No longer have a problem with this myself but looked up the above anyway :) !
Solution 3
Merging a .reg
file or editing the registry manually is the most reliable option, but perhaps you could simply run assoc .bat=
from an admin command prompt.
If neither works, perhaps Windows is hiding file extensions from you and it's actually a .bat.txt
file. Uncheck "Hide extensions for known file types" in File Explorer Options (formerly known as Folder Options) and rename the file.

I installed gvim on windows vista and got really excited to edit EVERYTHING with it. I associated .bat files with gvim, and now I can't get bat files to run... oops!! Could anyone explain how to reassociate .bat files with cmd.exe so that double clicking on them will make them just run?
EDIT: I followed Jim's advice below by deleting the registry key. After restart bat files are still opening in my text editor. I double checked my registry, and the key had been recreated. I then discovered that the text editor was set in Control Panel > Default Programs > Associate a filetype. I changed bat files to open with the Cmd.exe, but Cmd.exe just opens without running the batch file. I'm guessing the problem is still in the registry.

Rustavore about 12 yearsThanks, Jim! I found this key, but it's still opening in my text editor. Maybe I just need a restart.

Rustavore about 12 yearsStill not working. I've edited the question with more information.

Rustavore about 12 yearsWorked like a charm! Thanks, Bali C

mightypile about 10 yearsI have the same problem as GitNinja, but with a different text editor. I normally would prefer an explanation of the steps over a link to another site, but I reviewed the reg file at sevenforums.com and realized it would require a long explanation of the registry's structure to do that. I looked through my own registry for differences, then ran it. It worked perfectly for me on Win8.1Pro to solve the problem.

Math1000 over 8 years+1, this actually solves the problem unlike the common suggestion of just changing HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.BAT\UserChoice

assoc .bat=
worked perfectly for me (on Windows 10). Thank you.
