So a few months back I started having mouse keys randomly turn on. I can turn it off but they will randomly turn back on later. (I assume its not random but I use 10 key just rarely enough that I have no clue what does it.
It also gets turned on under Control Panel\All Control Panel Items\Ease of Access Center\Change sign-in settings
Not sure if this is a symptom or part of the cause but this gets replicated across from my laptop to a desktop i built after all this started signed into the same microsoft account.
I will turn it off and a few days later it will be back on. Windows 10 pro.
