Having a bootable NPE was great! Now we don't have it at all.
Never saw anyone get it to work on a bootable windows 10 PE (not that I would touch windows 10 if I could help it). Since NPE wasn't running on at least windows 10 PE (bootable) it refused to scan windows 10 (installed) because it won't offline scan a newer OS from and older one (for some reason, all it really needs is registry and filesystem access)
Now we have NBRT on Linux with no NPE. When do we get NPE that can scan windows 10 offline? (either from PE mode or from Linux)
When do we get NPE on NBRT that can scan anything prior to and including Windows 8.1 back? (we used to have that before NBRT went to Linux)
