I have a hacktivated windows 8 installation, which regularly pestered me to update to windows 8.1. These untoward advances were always rejected by me, as i always clicked 'remind me later'. Since a few days i have observed high network activity and now suddenly windows is asking me to reboot to install windows 8.1. Now I am afraid to shut down or restart my pc. What will happen if I let it update? Will the crack persist? Will my pc get screwed?
