The first few days I allowed access, but I cannot find how to stop all automatic updates...

Reason is I have had the PC crash once a day on me before I could save my work.
Not even sure if it is M$ doing this or some other "helper" that seems to think errors are occurring.
I cannot have this happen while I am gigging, seems like only when online but I am quite distraught that I get the same looking message twice about how they are "helping" me fix errors which I don't notice.
The Event Log said something or someone is trying to use a blank password for access on my PC.
Whatever that means I don't Like it so any help appreciated.
Windows 8.1......very fast..........but what a crock of shit that they have cooked
up about "helping" me...
