Basic win 8.1 question

How long is it before win 8.1 actually crashes, something didn’t work and i uninstalled and reinstalled the program. And had to restart, before the process started, the blue screen appeared saying my computer ran into a problem and KERNEL_SECURITY something i didn’t read in full. This is the first blue screen on my win8.1, should i be concerned? How many times/chances can it give before actually crashing.

Your question has nothing to do with either.
I suggest you ask Microsoft.
