Hello. This is my Batch OS project I've been working on since April. It uses a Window Manager I made using the VT100 implementation in most terminals to do this kind of graphics. It's also got full multi-tasking, shell, OOBE, Programs, and many other things. As stated, it's written in Batch (CMD). I'm not calling it "pure batch" since it uses a few extensions (like
getInput64.dll
getInput64.dll
for input, and a couple of VBS scripts for audio) It's got a whole wiki on the github page if you're interested in learning more about how it works, or making some apps yourself!
