    This really helped! I was afflicted by the “Windows Media Center has taken over my computer” syndrome. Actually WMC had substituted its icon for every icon that referred back to an .exe file. Click on the icon and you would get WMC. I used the fix for .exe extension, then rebooted, and all was back to normal. Thanks.

    Some of these do not work on my system.

    They are:


    I keep getting the message:

    “Cannot Import C:\Users\’User Name’\Desktop\****_fix_w7.reg: not all data was successfully written to the registry. Some keys are open by the system or other processes.”

    Could you please get back to me on these?

    Thank you.

    thank you so much! I am 12 years old and tried to open a game with explorer.exe to fix it and accidentally made it the default for all .exe files. This has saved my neck as my mother would probably kill me for breaking the PC! I even tried opening command prompt and restarted Explorer.exe to no avail.

    Just a big thank you!

    One good deed deserves another so Im paying it foreward,

    Method 1: I would suggest you to unregister and re-register windows installer and check whether it helps. To do so, please follow the steps below:

    Unregister and re-register the Windows Installer

    a) Click Start, click Run then type cmd in the dialog, and then click Command Prompt.

    b) At the command prompt, type the following, and then press Enter after each line:

    MSIExec /unregister

    MSIExec /regserver
