Fix broken EXE file association in Windows 10

You might encounter a situation where you may not be able to open any .exe files or shortcut link files, i.e., EXE or LNK files. You might instead get a “Open with” dialog box, or it may open the file in another program. This happens if the file association of these file extensions may have got corrupted on your Windows 10/8/7 PC.

broken EXE file association

EXE files will not open or not working

A corrupted Registry, caused either by bad software or malware or any other reason, can lead to your Windows being unable to open a particular file type.

When file associations for executable, batch, or COM files are changed, it could cause your executables not to start. For example, when you try to click open a .exe file the programs will not start, or the Open with box might appear, or Windows will say that it cannot open this file and ask what you would like to use to open the program, or it may start a different program.

    It can be done easily using a simple utility “unassoc.exe”
    Download link:

  2. Thanks for the suggestion Nitin about that tool has EXE extension, so it will not open until we run the reg file.

  3. I never seen a case where exe/lnk files are failed to open. The only possible case for the failures is either exe is corrupted or lnk has wrong path. You can not do “open with” operation on exe files. Am I missing anything here?

  4. Thanks for the comment Techibee. Lot of cases somehow people open EXE with some other application like Notepad and we can’t revert it back. Such cases we could use this Method. I personally help lot of people with the same issue so though of making it as an article. Just Google it you’ll find of the threads about it.

    Hope this answers.

  5. After posting the comment, I have seen few forum threads talking about this. I am curious, how the OS related exe are able to execute when the default program for exe is files is changed. All the installed programs also should fail as the exe assoc is set to notepad that means system should go complete useless.

  6. I haven’t tested it myself mate … But I understand your point that’s why broken EXE extension could be a pain.
