Windows NT became capable of multi-user operations primarily through the efforts of Citrix Systems, which repackaged Windows NT 3.51 as the multi-user operating system WinFrame in 1995, launched in coordination with Wyse Technology's Winterm thin client. Microsoft licensed this technology back from Citrix and implemented it into Windows NT 4.0 Terminal Server Edition, under a project codenamed 'Hydra'. Windows NT then became the basis of Windows 2000 and Windows XP. Microsoft Windows systems support graphical terminals via the Remote Desktop Services component. The Wyse Winterm was the first Windows-display-focused thin client (AKA Windows Terminal) to access this environment.
