Windows 10: Windows 10 problem

Hello.
I have Windows 10, and i actually never had any problems with it. But yesterday i left my pc turned on, and today that i woke up, i tried to shut down my pc ( by going on the start menu) and it didn't open. I just saw a flick and nothing happen.
Also i can't open the calculator, which happens the same thing ( flicks and nothing happen). If anyone have a solution, i would like to read it. Thank you. *Rolleyes

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?

 

There are some "bugs" on Windows 10 in the first Builts/versions.. check for updates/upgrates

 

Right click Taskbar
Pick Task Manager
Select Windows Explorer and press the [ Restart ] button (lower right)

If that doesn't help
Press Alt-Ctrl-Del
Select sign out
then shut down
