Need Computer Help

My friend had the same problem, he desperately needed Windows to continue his studies, but there was no solution. So you understand, I called all my friends back to try to fix it, but in vain. Thank God that at least my friends helped me with writing letters to make the situation with homework a little easier. But then some time passed, I think two weeks, and everything was found, you should know how happy I was that I managed to install that Windows on that computer, even though it was already old, but it performed its functions. I hope that you managed to do everything clearly and find a solution to the problem.
