Windows 8.1 vs Windows 10. Who consumes more RAM?

Question

Windows

Which OS in standby mode of the two listed windows consumes more RAM? Well, in general, who is more gluttonous?

Answer 1

What do you care about the use of memory in standby mode?
Even between different builds of the same version there is a difference (for example, between Win10 1909 and 2004). But, first of all, it depends on the installed unnecessary rubbish, on drivers and marketing garbage installed by drivers, on autorun programs and background services ...
If you avoid the topic of holivars, then Win8.1 is needed only for those (outdated) PCs for which There are no drivers for Win10. First of all, this applies to laptops, where drivers are often bad and any external equipment that still works fine, despite its antiquity.

Answer 2

Approximately the same - 1-2 gigabytes of memory consume.
What does more greedy mean?

Answer 3

I still use Windows 7 for servers, and I won’t change it for anything. After installation, the system is cleaned of unnecessary services and autorun, the output is that clean Windows consumes 540 MB of RAM in idle time.
