    Hello!
    How to turn Windows Defender back on, after disabling it in O&O Shut Up 10?
    I switched it back in OOSU but it still doesn't work.
    I also tried using different tutorials, but usually nothing happens, or I get error 577: Windows cannot verify the digital signature... etc...

    Thanks alot for any help!
