Windows 10: Some keys only work occasionally

So recently i kept getting this problem where certain keys R,T,F,G,V,B work for some time and goes unresponsive but it usually just goes back to normal after a few minutes, but today they just stopped working and it is really irritating. My drivers are up to date, so is my windows and there were no debris in between the keycaps.

Occasionally "Microsoft print to pdf" creates empty files

Have already done all of the steps suggested in that link.
The problem only happens occasionally; maybe two or three times a day.
Happening on several PC's, the only way to catch it before it goes to customers is the size of the file created.
If it is 0 or 1kb, it's a blank document.
Microsoft Print to pdf was working fine until about two weeks ago.
Thank You
