Making a Folder System Hidden
Now, we get to make a folder system hidden. We will continue from Step 1.
Open Command Prompt by going to Start, Run and typing "cmd". This will open Command Prompt.
In Command Prompt, type the following:
cd\
Press ENTER.
Then, type this:
attrib x +s +h
Press ENTER again.
If you named the folder something other than x, then adjust it as necesary.
Congratulations! You just made a system hidden folder. It will be hidden from prying eyes, unless they know how to view it, which I will show you next.
In keyboard preferences > layouts > kb layout options > caps lock key
behaviour
I had caps lock behavior set to "caps lock toggles Shift so all keys are
affected".
This is not the default setting (although I can't remember changing it).
As a result pressing the numlock key while caps lock was enabled in effect
triggers a shift+numlock which enables mousekeys.
Setting the caps lock key behaviour back to default ensures that numlock
only enables/disables numlock even with capslock enabled (as you'd expect).
This almost certainly solved it for me.
