I am Dave Plummer, author of Windows Task Manager, Zip Folders, and worked on Space Cadet Pinball, Media Center, Windows Shell, MS-DOS, OLE32, WPA, and more.
Hi Reddit, I'm Davepl and I'm stoked to answer any questions you have about the projects I worked on or about working at Microsoft during the 90s in general. I was on every major operating system from MS-DOS through XP & Server 2003.
My general timeline starts in 1993 on MS-DOS, where I worked on Smartdrv, Doublespace, Setup, Diskcopy, and others.
I soon moved to Windows NT, where I started in RPC/OLE and moved to Windows shell to undertake the port of the Win9X user interface over to Windows NT.
Along the way I worked on our initial version of Media Center, Space Cadet Pinball, Windows Product Activation, and others.
For background info on how I got to Microsoft, the stories of how Task Manager, ZipFolders, and Pinball came to be, and proof (video of my cardkey, office, etc) please check out the following video:
