Yeah and it has a whos-who of hacked and cracked Windows10 'WinPE' / preinstalled environments which I find amusing, like for example:
Gandalf's-Win10PEx64-19H2.iso
Gandalf_s_Windows_10PEx64_Redstone_5_build_17763.iso
Bob.Ombs.Modified.Win10PEx64.v4.8.iso
WinPE10_8_Sergei_Strelec_x86_x64_2020.06.09_English.iso
I discovered it a few days ago and used the latest (1.0.19) version to boot the Linux Mint 20 iso and install it to my laptop without problems. Looks like there's also a "Tested ISO" page[0] on the official site.
