thumb|Windows NT Diagnostics in [[Windows NT 4.0]] Windows NT Diagnostics is a diagnostic tool included in Windows NT 3.5x and Windows NT 4.0. As it's file name states, it is the Windows NT counterpart of the DOS-based Microsoft Diagnostics.

As Microsoft Diagnostics, however, became deprecated with the release of Windows 95, Microsoft instead began work on a new diagnostics and information tool for both the Windows 9x and NT lines. For this, the System Information tool from Office 4.2 was extended to show more advanced information about hard- and software, which would ultimately became part of Office 97 and then as part of every Windows version starting with Windows 98.

Plans to remove Windows NT Diagnostics reach all the way back to Windows 2000 build 1773, where the Start menu link to it was removed, however, the application itself was not removed until build 1989, where it was replaced by a stub for System Information, with a later build also removing the stub.
