    Win 10

    asp.net machine account is taking over your PC

    Hi there!

    It can happen - which is a scandal I think - that you´re deleting your admin-user profile (same in Win 7/8).
    It can be your bad or this can happen by installing certain programs.
    Then you´re not able to do anything with your OS (install/uninstall programs, use cmd a.s.o.).
    You locked yourself out. The asp.net machine account wants a password for everything which you of course can´t know.
    In MS support forums there are hundreds of complaints, most of them marked as solved, but no real solution can be found.
    Which is quite embarrassing.

    Here is one solution for the desperate : The trick is basically to exchange cmd.exe with magnify.exe

    If you´ve encrypted your system drive, first use a rescue disc to completely decrypt it.
    Otherwise this won´t work.

    - Burn a Win 10 setup/boot DVD or use an USB stick to boot.

    - Shut down system. Boot with DVD or iso as you would to install new OS.
    Do NOT click on INSTALL!!

    - Search for cmd instead. Now you want to know which is your system drive.
    To find out, use the notepad (open cmd and type: notepad)
    Once the notepad is open, click on: "file" and then "open".
    Here you can find out the system´s drive letter. Should be D: not C:, but can be C:, E:, F: a.s.o. on your PC.

    Once you know the drive letter, go back to cmd and type in the drive letter: e.g. :


    Then write:

    CD Windows\system32
    ren cmd.exe cmd.old
    ren magnify.exe cmd.exe
    ren cmd.old magnify.exe

    and Enter of course

    - Remove the DVD/USB-stick and reboot.

    - Instead of logging in, search the login page for the magnifing glass option on the right side.
    When you click on it, the cmd should open with admin-rights.

    - Write in cmd: net user administrator /active:yes

    You´re in control again! You´re the admin! Yes! Change your user account to admin and remove the password of asp.net machine account. ​(control panel - user accounts)

    Now you need to reverse your actions:

    Reboot again with DVD/USB-Stick. Open cmd and write:

    net user administrator /active:no

    D: (your system drive letter)

    CD Windows\system32
    ren magnify.exe cmd.old
    ren cmd.exe magnify.exe
    ren cmd.old cmd.exe

    Hope this helps.
