Microsoft launched its first retail version of Microsoft Windows on November 20, 1985, and in August, the company struck a deal with IBM to develop a separate operating system called OS/2. Although the two companies successfully developed the first version of the new system, mounting creative differences caused the partnership to deteriorate. It ended in 1991, when Gates led Microsoft to develop a version of OS/2 independently from IBM.
