Windows 10: Windows 10 search problem

Hey, I'm new to this site and have just downloaded windows 10 from windows 7within the past 24 hours to discover it doesn't take keyboard inputs well. Whenever I try to type into a word processor(ms word), or a search engine such as chrome, edge etc. the program freezes. The rest of the program's remain functional, but the one typed into remains frozen. It does this for the on screen keyboard as well. Any help solving would be greatly appreciated!

Windows 10 login problem

Hi. I installed windows 10 on my friends computer, and his computer has a problem with overheating, so when I wanted to type his account details, the computer shut down. Then when I reopened it, is displays "Other User" and under are two columns, where
it says to type the email and the password. I tried three different accounts and it says that the password is incorrect. Please, help!

 

Windows 10 Problem

After I updated Windows 10 today as I was instructed, I can no longer get on the internet. My wifi no longer shows up to click on it. It was working fine until I allowed the install. I have tried restarting the HP Spectre x 369 laptop and the router,
but this has not helped. (I am using a borrowed Apple computer to search for a solution.) I need help to get back online. Can anyone help or tell me who I might contact for help?
