1. I was trying to install andy emulator http://andyroid.net/

    - it took alot of time so i aborted it. it suggested to reboot pc because of incomplete installation.

    - after reboot keyboard stopped working.

2. Till now I have tried

    - restarting

    - completely uninstall andy and its files.

    - deleting  upperfilter from registry as per internet solutions. It didn't  have lowerfilter and restart.

3. windows 10 is up to date. everything was working when it was updated.

4. version 1607 ( os build 14393.953 ).

Additionally I tried this ,
