Probably just windows updateTry restarting it again to see how long it takes
if its not your start up settings getting forgeted up, its your drive is dying. back up and replace immediately, or you'll waste time trying to fix it like i did.
It will also only let you go on cnn.com
Not an update and it's slow every single time
Take out your hard drive and post pictures of both it's sides.
I have never done anything with the inner workings of a computer before. It's also my dad's pc so I would need permission from him before I take it apart.
If it's taking this long your computer has probably been raped with malware.
Is it a laptop or desktop?
Desktop running win10
I'm guessing an HDD and not an SSD?
