By “tried disabling input from the Windows key” you mean you have physically removed the key from keyboard? This is what I had to, as my ‘Esc’ key had permanent contact.
I disabled it via software, can’t remember what the program was called :/ Autokey I think. The problem with the windows key isn’t bugging me that much these days. Having to go into display settings to change the brightness is very annoying in the other hand.
