Windows 10: Problem with reset Windows 10

I am trying to help someone to reset his PC to give to his daughter. He tells me that when it is halfway through, it says the reset isn't working and changes have been undone. He says he upgraded from Windows 7 successfully so cannot fathom why a reset will not work. Windows 7 Home was on the computer when he bought it.

I am attaching a screenshot which he sent to me.

Can anyone tell me why a reset wouldn't work, please?

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?

 

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!

 

Because built-in Windows reset function is extremely unreliable. I would recommend exporting the non-Microsoft drivers by opening a Command Prompt (Admin) or "Run As Administrator" command prompt and running:

dism /online /export-driver /destination:F:\Drivers

Change the path in red to match a folder that you create on an external storage device such as a USB flash drive to hold the drivers.

Clean install Windows 10:

Then any devices that don't get Microsoft drivers can be installed from the drivers previously exported.
