.windows Domain Information

Country flagLogo for .windows Domain

Operating system software sits behind .windows, a restricted extension from ICANN's 2012 New gTLD Program. The string is an ordinary English plural noun with enormous independent demand — glazing, construction, and home improvement are substantial industries that describe their entire product with this word — placing it among the most heavily contested dictionary grants in the round.

Use relates to operating system downloads, support resources, and developer destinations. Registration is closed to the public and the extension carries no aftermarket. Operating system update and activation pages are also among the most impersonated destinations on the internet, which gives the closed namespace a direct security rationale alongside the trademark one.
