Where can I find a stripped-down build of win7 in the trash?

Question

Windows

There is a nobuk, more or less modern, albeit low-powered. I'm trying to find the easiest axis for it to place a couple of tiny VMs on it. RAM is only 2GB, of which 1.6 is available somewhere (the rest is eaten by vidyuha). In general, ideally, I am ready to allocate about 200 MB of RAM purely for the axis.
At first I looked at light linux, but there is either a complete disaster with drivers (in particular, Wi-Fi, which is critically needed, alas, I can’t write and configure them) and rdp, or initially it takes more than 500 MB of RAM.
In addition to full-fledged distributions, I tried xenserver, it also eats a lot of memory.
And in general, I don’t have enough knowledge on linux, so I decided to move on to plan B. In addition, linux hypervisors have difficulties with forwarding equipment to VM.
Plan b
win2003 and XP - all of a sudden, also a problem with drivers, specifically for network cards, they just fall into the bluescreen, regardless of the version and developer of the installed driver.
Plan B
So far, only wines 7,8,10 remain - but they initially gobble up memory again. At least there are no problems with firewood.
Finally, the question is: Where can I find a castrated Windows purely for launching VBox, or an instruction that says how to cut off everything in general (services, components, etc.), so that the state is on the verge of a dying invalid, but at the same time how does it work?

Answer 1

bare server core eats 180 mb, but you can stick hyperve on it. And there will be problems with the Wi-Fi drivers.
plan D - repurchase of RAM
plan I - learn Linux.

Answer 2

And what, in the BIOS, the appetites of the integrated vidyuhi cannot be reduced, megabytes of commercials up to 64?
