Drivers are up to date but the keyboard is still not working

So I encountered a weird error. I was installing VM but when I restarted my laptop, my keyboard stopped working K. So I ran Diagnostics to check if it is the hardware issue, which luckily was not. So I used the on-screen keyboard to log onto my system to check if I need to upgrade my keyboard drivers. There was the tiny yellow mark on the near my keyboard driver. And I downloaded newer one from the internet and but that didn’t help either. It said you already have the up to date driver.

I found a very useful link about it – https://support.microsoft.com/en-us/kb/256233

What they said is simple enough but one has to very careful while editing Registry Editor because any mistake can make you reinstall your operating system.

Using your onscreen keyboard, type Regedit in the run. This will launch a window as shown in the picture below.

On the registry menu, click computer and then expand HKEY_LOCAL_MACHINE. Then go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96b-e325-11ce-bfc1-08002be10318}

Double click the upper filters to remove Lkbdflt2 value.

Then go to other location : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96b-e325-11ce-bfc1-08002be10318} and in upper filters  remove Lmouflt2.

Then close and restart your computer. Everything should work fine now.
