The original 1965 serial The Chase does not identify Microsoft as the maker of the robots — indeed the company wasn't even established for another decade. This was later subject to a retcon in the aforementioned novel.
In the real world, Microsoft manufactured the Xbox, and released Windows Vista and Windows 7. These links, however, have yet to be made within the DWU.
Word, PowerPoint, and Outlook also exist in the DWU, but no connection has been made in-universe to Microsoft or to the Microsoft Office suite, to which they belong.
