Windows 95 build 73f

This build was leaked on BetaArchive by member sunnyblueman. It is nearly identical to the previously leaked build 73g. However, this is an internal Microsoft build, and thus was not released outside Microsoft. It features an internal version of the WinBug tool, while 73g has WinBug for external testers. It is safe to assume earlier compiles of this build (73a-73e) also exist.
