    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!

    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
