Optimizing Windows 7 for an old machine?

Question

Windows

Good afternoon, please tell me one moment. There is an old car (2010), it hangs very badly, according to the tests everything is fine, I changed the thermal paste.
For the sake of verification, I downloaded one of the lite assemblies from the torrent (please don’t hit it hard), the car started up and works smartly. I want to do it wisely (demolish the assembly, do everything by hand) and give this car for office needs and watching movies.

Question: Does it make sense to demolish the lite assembly if it starts up and works fine? (I understand that anything could be stuffed there, and it will be hard to catch it).

If I remove it, then how to bring this matter to its logical conclusion, if there is any kind of infa which services to disable to increase performance, or some kind of tweaker. I will not put Linux on the machine, because I will give it to the left hands, and people will not figure it out without dancing with tambourines.

Answer 1

Use only msdn images and do all sorts of "facilitations" yourself. All these Vasyan lite builds from torrents, well, it's just awful. What is not there.

Answer 2

Does it make sense to demolish the lite assembly

In this assembly, lite is only in naming.
But in fact, these are left-handed programs, and the necessary functions are disabled.
Put the original image - this is the best lite assembly.
