Windows 95/4.00.73f

Windows 95 build 73f was leaked by member sunnyblueman, along with builds 99 and 116. It is identical to build 73g, except that it is an internal Microsoft build and thus contains an internal version of the WinBug program. 73g, on the other hand, was released to testers and contains a public version of WinBug.

This build is also affected by the  error, which can be fixed just like in other builds.

Hidden Start button and menu
This is also the earliest build to contain the new Start button (though it is first enabled by default in build 81), located in. Even though this is an internal build, it is not used and was likely toggled on and off during the compiling process. However, member Hounsell successfully enabled the hidden Start menu and button in build 73g, the same procedure can of course be applied to 73f as well. A tutorial is available here.
