Just personal preference, the Recycle Bin was removed from the 'Desktop' and added as an Explorer file manager Favorite. It's cool that the Favorites dropdown 'RECYCLED' icon even changes when the trash is not empty, just like the Desktop icon. Microsoft thought of everything with their greatest creation - Windows 98 SE (Stupendous Edition).
I was recently working in Windows XP. When Explorer auto-selects files with mouse hover (as it likes to do) in the Recycle Bin view then File -> Empty Recycle Bin is not available. Whose silly idea was that? So the user needs to do a little mouse cursor dance just to empty the bin, from File dropdown anyway. Hmm, restore file or empty trash, restore file or empty trash - imagine Homer Simpson thinking. Maybe a minor example of the software trend to take control and dumb down the user interface.
In all fairness, Windows 98's Explorer does not provide a Recycle Bin File -> Restore option until a file is selected, not even greyed out. So new (back then) users may not even be aware of the Restore feature. Of course, the right-click context menu reveals these options.
Computer Chronicles aired an informative tribute episode to Gary Kildall if anyone's interested, titled 'The Computer Chronicles - Gary Kildall Special 1995' (runtime 28 minutes). It was very good, is on YouTube and probably at archive[dot]org.
To me maybe the most important but lesser known contributors to Microsoft's success is Tim Paterson, programmer of QDOS (Quick and Dirty Operating System) in 1980, which became 86-DOS and was acquired by Microsoft the same year, quickly re-branded as MS-DOS. He went on to work for Microsoft too. To me Bill Gates' biggest success was his ability to leverage people and take advantage of opportunities.

Tim's (old) blog 'DosMan Drivel - From the original author of DOS' can be found below. Although there are only a few entries, his experiences and insights are fascinating.

Xenix is interesting, never knew at one point Microsoft was working on a Unix-based OS, snippet from MS-DOS Wikpedia pasted below. So much rich computing history in the 1980-1990s. I always thought of these old DOS' to be really basic, like okay i can boot my computer and read/write to disk, now what. Just my ignorance, not uncommon. Cool to have some limited insight into computing history.

Microsoft omitted multi-user support from MS-DOS because Microsoft's Unix-based operating system, Xenix, was fully multi-user. The company planned, over time, to improve MS-DOS so it would be almost indistinguishable from single-user Xenix, or XEDOS, which would also run on the Motorola 68000, Zilog Z8000, and the LSI-11; they would be upwardly compatible with Xenix, which Byte in 1983 described as "the multi-user MS-DOS of the future". Microsoft advertised MS-DOS and Xenix together, listing the shared features of its "single-user OS" and "the multi-user, multi-tasking, UNIX-derived operating system", and promising easy porting between them. After the breakup of the Bell System, however, AT&T Computer Systems started selling UNIX System V. Believing that it could not compete with AT&T in the Unix market, Microsoft abandoned Xenix, and in 1987 transferred ownership of Xenix to the Santa Cruz Operation (SCO).
