Windows Simple Batch Shutdown Timer

It seems like after every reformat I end up rewriting this timer. It's a simple batch timer for Windows 10, most likely works for other Windows OSs, but I haven't tested. Feel free to post your results! Thought I would put it here in case anyone needed something quick like this. I use it for listening to music before bed. Place the code into a .bat file. I put mine on my Desktop for quick double-click action. Once opened, the sleep timer prompts you for a sleep time (in minutes). Feel free to modify the timer for whatever suits you best!
