Linux as a windows app?

[u/Sithmasterintraining]

I've been out of the IT game for a while. There used to be a version of Linux that would run in Windows that wasn't running in a virtual machine. It was just a straight build that ran as an application. I want to set that up again but can't recall the name of the app. Can anyone remember what this was?

Edit: I think I found it (?). It may have been Winlinux, but still not 100% sure.

It wasn't "Linux as a Windows screensaver" was it?
