So I have 2 keyboards and out of nowhere I noticed my keyboard functions broke sort of. The windows key doesn’t work anymore and the alt key opens the windows menu instead. Ctrl alt del doesn’t work either and nor does my Alt z shortcut got the nvidia overlay. Just to clarify all these keys work If I were to type and stuff like that. Moving on, I plugged my other keyboard in and everything works perfectly fine all the short vid and the windows key. I have a software for the keyboard doesn’t work and all the keys are set to default function.
Try a clean boot and see if it changes anything – make sure to read instructions and make sure NOT to disable any microsoft services or windows won\’t load right – https://support.microsoft.com/en-au/help/929135/how-to-perform-a-clean-boot-in-windowsif clean boot fixes it, it shows its likely a startup program. You should, over a number of startups. restart the programs you stopped to isolate the one that is to blame.
