You just reminded me.

At one point I had Windows take up two drives, one for boot and one for games. However, I only ever really used it for this one piece of software that I couldn’t get working on Linux, so I nuked it and reinstalled Windows on the smallest drive I have, just for that software.

Two weeks later I got the software working on Linux, and I completely forgot I even have a Windows partition up until now. It’s been months.
