at some point after the Fall's Creator Update my keyboard started to act weird. It seems to use short cuts on its own. For example: immediately after typing the letter y, upon hitting the spacebar a context menu opens. Upon other keys, new Browser windows are opened (sometimes in incognito mode) or the Browser is closed altogether.
I can't find anything about this on google (probably because I'm not using the correct search words / phrases). This is not restricted to my browser, but affects pretty much everything. Removing the keyboard from the system (driver-wise) did not help. Scans for Viruses and/or Malware came up negative.
I am getting desperate here and my patience with my computer is running out. Any help is appreciated.
