I have 2 Win7 laptops and 2 Win8.1 desktops, and I was rescued when I starting using Win8.1 by these replacements/enhancements:
I do not use the Microsoft online account et al as my userID or password on Win8.1. The setup tries to trick and/or coerce you into it, but you can "just say no" if you try.
One of my Win8.1s is an all-in-one with a touchscreen. If you have one, I can also recommend Touch Mouse Pointer from
