After installing updates on windows 7, keyboard doesn't work when windows lock screen pops up, and so unable to unlock PC RRS feed

  • Question

  • Hi All,

    I am not sure if this is right place for my problem.

    Yesterday my windows7 installed updates and required reboot.

    After reboot, chkdisk started, then when lock screen appeared I found that my keyboard doesn't work, so no way to unlock.

    The on-screen keyboard also doesn't work.

    The restore always ends up with errors.

    I tried all kind of stupid things, like checking that my key board is working, check other keyboard(s), etc. etc., and even more,

    when I restart PC, keyboard works, for example I can go to BIOS menu, navigate there, even go to recovery menu,

    navigate there, but as soon as lock screen comes, I can do nothing. Even Caps-Lock, Num-Lock don't work.

    Can you please help me?

    Thank you in advance,
