This is a trial version of Windows 2.11 for the PC-9801 series. It was a cover disk for Oh!PC magazine. After booting to DOS, exit the menu (if applicable) and run WIN.COM.

You boot up into a memory configuration warning, then the default interface for this trial edition. It's a simple menu. You can edit the WIN.INI file to change the shell to, say, MSDOS.EXE, which functions similarly to File Manager from Windows 3.1.

It comes with a couple of apps such as calendar and notepad, customization via the control panel, and reversi for a bit of fun. I don't recall at this point, but I am pretty sure Page Maker and Excel were non-launchable apps, maybe they just posted an informational window, I forget exactly.
