Windows 95 build 81 is the earliest leaked Chicago build which uses the single Start button and menu by default, though 73f is the earliest leaked build to include them. It is also the earliest leaked build to introduce the now famous "X" close button on windows and by this point, the overall UI was mostly done and merely refined in later builds.

1. Prepare disk with fdisk, reboot, then format (format C:).

Virtual PC issues

If you're installing this build in Microsoft Virtual PC 2004/2007, make sure to select "XGA compatible" as your display adapter during setup. This build appears to have an issue with S3 and VGA drivers on VPC and will not boot with them. If you want a higher resolution, you can use the Super VGA driver from build 73f/g - select "Other..." and point to a floppy disk containing files MSDISP.INF and SUPERVGA.DRV from build 73f/g.
