Windows Updates won't install security updates or other updates: Error 8000FFFF.
FixIt doesn't help.
Manually downloaded Hotfix for Windows KB947821 but it took over 3 hours to install, so I cancelled it. I'm not sure this would have even fixed my error.
My computer runs insanely slow. I've turned off Windows update automatic updates because they fail every time and my computer runs them on start up.
Please help with next steps.
