Windows 10: Mouse/Touchpad issues, and login issues.

I updated my laptop but during the update I accidentally turned it off or someone did, when I turned it back on I had no mouse/touchpad to use. I then tried factory reset but it failed, I tried a couple of different ways, but none worked, although my touchpad now works on the troublshooting screen but only that screen, but now when I turn on my laptop it loads ok sometimes, I enter my user password and takes ages to load to the home screen, but once the home screen loads no icons on the task bar, or by the clock. I can't use the keyboard or mouse/touchpad basically frozen or taking ages to
