Windows NT 3.5x is a family of NT-based operating systems released by Microsoft. These versions of Windows are the last of the NT series with the Windows 3.1-style user interface, as Windows NT 4.0 would introduce the Windows 95-style shell. These versions succeeded Windows NT 3.1.
Notably, an early version of the Windows 95-style shell is available for Windows NT 3.51 via the NewShell update. NewShell replaces Program Manager and adds a new desktop, taskbar, and user interface graphics.
On 15 May 2020, the source code for Windows NT 3.5 build 782.1 was leaked.
