@retrage After your last commit I have to admit I didn't retest Windows. Did it work for you? I get the following error:

Going back to 282ebc0 makes Windows boot fine. So I think there needs to be a little bit more refinement on the memory map.

Both Linux and Windows also use MemoryAttributeTable along with an EFI memory map to set the RuntimeServices page attributes.
