Solved Stuck at login screen Windows 8.1

My brand new Acer Aspire E15 was doing fine, but after a windows update the keyboard stopped working (Error number -19). I could login normally by using the on-screen keyboard. But the keyboard didn't work either when booted into windows, it was very annoying to use the on-screen keyboard all the time, so I wanted to fix the problem, to fix the keyboard error I decided to boot into safe mode. But now my trackpad stopped working too! Which means I can't select the on-screen keyboard at the login screen to type my password, and I can't type my password with the keyboard. I'm stuck at the login screen now, how can I fix this login problem and my keyboard problem? I don't have a recovery CD / USB and I can't make one because I don't have a CD / DVD right now. I'm typing this from my macbook.

Nevermind, I got it working by pressing Alt + F10 on startup and then refreshing the pc.

Edit: Jeez, that was a little overkill.


Umm... hold the power button to reboot? No reason for safe mode for an error 19.

Once you get logged in using the on-screen keyboard, head into device manager.

Right click the device with the error and uninstall it.

Then choose the Action "Scan for hardware changes"

That hopefully should repair the broken device configuration.

It wasn't overkill, I told in my post that my trackpad stopped working too which means I couldn't select the on-screen keyboard, I didn't have an USB mouse at the moment. Did you even read my post completely?

Indeed I did.

I suggested you reboot the machine, so that you could potentially regain control of your mouse and keyboard.

Overwriting the whole OS and reinstalling all your programs sounds like a perfectly reasonable alternative though.
