Both retained the rights to use OS / 2 and Windows technology developed up to the termination of the agreement ; Windows NT, however, was to be written anew, mostly independently ( see below ).

This was a major improvement: it featured a new, object-oriented GUI, the Workplace Shell ( WPS ), that included a desktop and was considered by many to be OS / 2's best feature.

This was one of the reasons for the chronic shortage of OS / 2 drivers for the latest devices.
