Answer 1

and internet access

You don't need to log in to the Internet, the main thing is the exit!

But I don't have an installation disk

Ask your friend TYZHProgrammer for an installation flash drive.
You need to go to the registry at:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

and change the EditionID parameter to one of the following:

1.Enterprise
2.Ultimate
3.Professional
4.HomePremium
5.HomeBasic
6.Starter

Reboot the system. Perhaps I did not check, in the properties there will be the correct version. But whether it will work or not, I don't know. You will most likely need an installation disk to start the update.
Now even in a village where 10 people live, it's not a problem to get Windows.
