Windows 10: Reset to Win 7 from Win 10

How do I delete a user when it does not have a name but a long number starting wit S-1-5-21-2703684248- etc. Tere is only one (1) user registered and that is the administrator.


My notebook is "too old" (circa 2009) to handle Win10, therefore I need to revert back to Win 7 starter. Win 10 installed for one (1) DAY.

Win 7 and Win 10 on network

I have home network with separate modem, router, and WAP's. My Windows 7 computer does NOT list the Windows 10 computers on network computer list but the Windows 10 computers network list DO list the Windows 7 computer.

Turned off firewalls, gave permissions, shared drives. Nothing allows Win 7 computer to access the Win 10 computers.

Any suggestions for a fix?

 

Win 7 and NVidia overclocking?

Just curious how you Win 7 users are overclocking your NVidia cards. Riva Tuner won't work. Any suggestions?

 

Win 7 and Win 10 on network

Thank you. Troubleshooter did not work. I ran all the listed commands in order and that also did not work.

None of the Windows 10 computers on my home network are on the network list of the Win 7 computer but the Lan connected windows 10 computer does show up on the Windows 7 computer network map.

Any other fixes suggestions would be appreciated?
