I'm forced to keep whatever the fuck I have. I can't end processes with the task manager (have to use taskkill /im  /F), can't run MSConfig, can't access folder and search options, and can't access properties.
I'm forced to keep this shit on here until my mom gets her 32874283 movies off here :/
There's my reason, what about OP?
You dont have like an external drive or a DVD burner?
