    Can't open EXE files. It says "Application not found" or "Windows can't open this file"
    I accidentally messed up in the regedit and changed many things I shouldn't have, now all exe file type changed. The extensions itself are not changed but the type is.
    For Example
    sampleimage.jpg --- JPEG IMAGE <---THIS ONE IS RIGHT
    sampleapp.exe --- "1%"%* <---THIS ONE IS THE PROBLEM

    I messed up specially in these parts
    HKEY_CLASSES_ROOT\.exe
    HKEY_CLASSES_ROOT\exefile

    I can't even open regedit now

    see the problem yourself if you want

    Since the damage that's been done is extensive and a system restore or system repair might not work. I would suggest a complete factory reinstall if an OEM or a clean install if you have a retail copy.

    You could boot into a Hiren disc and load the registry hive file you messed up and fix the problem assuming you know which settings you broke.

    by the way I could open an application if it's opened by a file
    example:
    I could not open MS Word by clicking the app, but I can open MS word by opening a .docx file

    • actually fixed it myself. I booted in safe mode and ran regedit there and fixed everything. I fixed this before I got the burned disc so I didn't actually get to use it though I thank you guys for introducing hirens to me.
