On my Lenovo Yoga 500-14ISK running Windows 10 Home, I am experiencing weird keyboard issues, some of which are listed below:
Double clicking on items in Windows Explorer opens the properties dialog (Also reported without any proper solution here.)
Sometimes in Firefox, everything works as if the Control and Shift key is stuck. I cannot use these keys at all. Interestingly, the keys are not really stuck since reopening Firefox gets rid of the issue.
In some other programs, (especially Spyder), some keys sometimes function as if the Ctrl key is pressed down, even if I haven't even touched Ctrl.
I have tried a full recovery without any luck.
I dual boot and the problem never seems to occur under Linux. Also, it mostly occurs only after extended use.
