How to work on your computer without using its resources?

Question

Remote access

Good day to all dear friends.
Immediately I want to apologize to the moderator, because I did not know in which tag to put this question.
You have to work with VPN and socks with a large amount of files. Gradually, the main OS becomes dirty and a lot of unnecessary, waste files appear. A lot of garbage appears in the registry and on the entire PC as a whole.
We need an effective method of getting rid of the subsequent cleaning of the PC after work.
To be more precise:
"Connect to another PC and work on it from your PC"
Virtual machines and similar methods, alas, are not suitable.
Thank you very much for your attention, I will be glad to any advice.

Answer 1

Virtual Machine
And I can't think of a reason why this might not work.
