I changes .exe (Default) files data value, and now I can't open .exe files. Can anyone tell me the normal data value for .exe?

Hello Nilson,

Thank you for posting in Microsoft Community.

I understand that you have changed the values of .exe file extension and now you are unable to open any .exe files. We will help you.

To assist you better, I suggest you to answer the below questions.

• How did you change the values of the .exe file extensions?
• What was the issue to change the values for .exe?
• Is the PC used for testing purpose or you have you changed the values for any developing purpose?

Please post to us with more information to help you better.

Assuming you changed the value data for (default), in this key: [HKEY_CLASSES_ROOT\.EXE]

If the Registry Editor is still open, you can change it back to "exefile" (without quotes). If you've already closed the Registry Editor, use this method to reset the correct value.

Double-click a text (.txt) file in your system.

(This opens Notepad.)

From the File menu, click New.

Copy the following contents and paste into Notepad.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.exe]

@="exefile"

Save the file with .REG extension.

Double-click the file to run it.

This fixes the .exe file type ProgID.

 

Registry Editor and Exe Files won't open

I recently changed the wrong value in the registry editor by accident, and now exe files wont open. I can't go back in to registry editor because it is an exe file. I have tried many things, like changing cmd.exe to cmd.com and opening command prompt,
but nothing I do inside seems to work. I also changed registry editor to a .com file format, but it won't open. Is there anyway to fix this?
