I felt desperate and courageous at the same time, so I thought I might try to follow the instructions on how to gather (clone?) all the necessary repositories and apply the patches described by our friend nalexadru. With some assistance from Perplexity (https://www.perplexity.ai/) to guide me through how github and codespace works, of which I know neither. (My background) I HAD some unix experience (sgi) dating back to the mid 90s. I remember very very little, but every little bit helps I guess. As far as getting blenderCompat applied to the latest version of Blender, I seem to have gotten to the point where I try to apply the patches for openexr and openusd but they both gave me plenty of errors. I am not sure what "patching" actually does. I have a hunch that the provided patch files contain some instructions which go through the cloned repositories and try to locate specific files and lines of code within them. I got plenty of errors unfortunately. Does that mean that the openexr and openusd have evolved/changed to a point where the patches no longer can find the instructed files and lines to apply their needed changes? At this point I am very lost, even though it was very interesting. In my youth I had also done some Visual C++ Maya plugin coding excursions, and managed to build 2 or 3 rather useful (in their days) plugins, but with an incredible amount of effort and curiosity. So I have been technically savvy in my youth, but I think I have reached my limits now. If we were together in an office, like in the old days, I am sure that with a little discussion and coaching, I would be able to progress further. Oh well. I tried. Thank you nalexandru for providing some instructions. They were helpful up to a certain point. I wish I could be more helpful to everyone hoping for a 4.4.0 win7 build. Anyone else with some better fresher technical knowledge that wants to give it a shot? Enjoy your weekends.
p.s. I found it very very interesting that I was able to do all this without installing a gigantic developer environment on my laptop. I wish I could have had such remote tools in the past. Installing Visual C++ was a huge procedure that took an immense amount of HDD space and time to download through much slower internet speed at the time.

You can also use vxkex with official portable zip or your own build (without any patching)... Vxkex is doing dll patching in real time.

But custom build is needed if you want to use cycles with cuda because official kernel_sm_XX.cubin file doesn't load (you only need to replace the file needed for your card and compiled with CUDA 11.8)

For optix i needed to use my custom build entirely because official build need a more recent driver to be activated.

I never heard of this before. Sounds very interesting, however both my browser and my antivirus complained about it. And after doing a search about it I find it a little too risky for my liking. There have been more than one version of this vxkex tool going around, one of them being fake? I really can't afford to mess up my laptop right now. Thank you for the information though.

Yes it's very usefull and i even needed it to build blender (for python and oslc.exe). The original author deleted his repo and his github account. I would recommand dotexe1337/VxKex for now.
