This is a simulation of a custom-made OS, inspired by Windows 8 (I have it!) There are 6 apps, a file explorer, and settings that can be opened by clicking them. The file explorer has a built-in music player. All programs (except C:Fix) can be closed by pressing the X key on your keyboard, and some have other keys you can press, like C to clear a drawing in Paint. C:Fix charges the computer's battery as well, so best you use it before your battery gets to 5% (it will shut down after that)
