i am with cbtillery135 on this one, the windows loader is kinda suspicious so i checked it in a safe environment.
The loader comes with a bunch of keys for all kinds of systems. i cant verify if they work or not. you can find them here: https://justpaste.it/31cvz
The executable itself seems to work like advertised but i cant verify any safety. virustotal gives 35 flags for several kinds of viruses here are the results: https://www.virustotal.com/gui/file/34cc664c49873468b5606d55795a39e83d15e37e7051cdd580569fd5987ea962
There are a lot of Win7 versions you can get for free so if you can, avoid this one.

Yeah, so when I was trying to unpack it to modify it in NTLite (to build a Windows image more appropriate for my system), Windows Defender popped up and told me a KMS activation script comes pre-bundled, which would normally be great, however this script is intended for Windows 10, and also counts as bundleware. Don't use this! It also comes with a software called Windows Loader, which is a Keygen software. Generally, I would consider this to be a version of windows to avoid. Go with a clean version of Windows 7, not one pre-loaded with viruses.

6 hours-1 hour wait me
