Is either a game system that blocked some of the screen from clicks and malware. I have yet to find this due to W10, the OS.
I am not Windows savvy. Any help will be greatly appreciated. The following problems greatly interfere with all operations.
Suddenly the following problems appeared in Windows 10 Version 1607 - (OS Build 147393.447)
left click unresponsive
right click>control panel > Appearance and Personalization > Display > Change Display Settings renders a gear icon on a blue background and stalls there.
Tray Task View.
Right click on settings renders the same page as above.
Other tray icons have vanished.
Windows left and right keys are dead.
The Windows Troubleshooter found and corrected some problems.
But it failed to address one.
"Potential windows update database error detected - not fixed"
Reboot did not cure any of the above problems.
