Its main purpose is to prevent malware from booting. In my experience its main purpose seems to be preventing me from booting things I want like ventoy flash drives, nvidia drivers, and Linux distros that don’t support it. Same goes for tpm module. Its main purpose seemed to be the switch keeping win 10 from upgrading. I turned them both off and haven’t felt the strong need to turn them back on yet.
That said, and my bad computing habits aside, you probably should turn them ON. I’m not sure they will do all that much realistically speaking, but if it isn’t getting in your way (and it shouldn’t), then ON isn’t a bad default state to be in.
I failed a class in college. It was impossible to make the credits up due to scheduling conflicts/the tight nature of my curriculum’s scheduling. I had to miss my graduation in the spring, and go back to school in the fall for one semester for one class.
I am now a C-suite executive at a mid sized engineering firm.
Don’t worry about it at all. Take the extra time to breathe, get other things in your life in order, and hell-maybe just have a little fun too. You’ll be fine.
