Windows

From ReactOS

Windows® is the collective name for a number of proprietary operating systems developed by Microsoft.

There are two major branches: the '9x'-branch:

• Windows 95 (SR)
• Windows 98 (SE)
• Windows ME

And the 'NT'-branch:

• Windows NT (3.x to 4.0)
• Windows 2000
• Windows XP (Home and Professional)

Preceding the above branches were Windows 1.0, 2.0 and 3.x, all of which were more or less GUI-frontends for DOS.
