Computer running very slow & freezing up ?

x2 on the Windows update and slow internet connection thing. Happens to me often. Since I use a mifi device and cellular, if it really gets bogged down I take the laptop and go for a drive, closer to a cell tower which seems to speed things up.

If all the other suggestions fail, you can go into Settings, Update/Security, find the Recovery option, and "reset this computer" but use the setting that saves all your files. That worked nicely for me a couple times.
