The OS Mockup Kit

The OS Mockup Kit is a kit used to create WNR and other forms of OS mockups, but can also be used for other things too. It was originally based on feandesign's WNR Kit.

It comes in four parts; Graphics, Sounds, Photoshop Addons and Camera Photos. There is also a lite version for people with poor internet (introduced in 1.0), along with The OS Graphic Kit (formerly known as OS Resources Kit, also introduced in 1.0) and The OS Sound Kit (introduced in 1.1), which are versions of the OSMK that lack fanmade assets.

History
During 2017, mockup creator Twiglets1888 decided to expand on fean's kit under the title "Windows Mockup Kit" by adding many new assets, especially ones for creating desktops and other OS screenshots other than bootscreens.

However, Twiglets1888 increasingly became tired of the drama surrounding the mockup community and left it, leaving the Windows Mockup Kit and a few other projects behind. Glosswired and Spriteclad decided that the kit should be continued, eventually renaming it to the OS Mockup Kit as it is known by today. While Spriteclad was the lead developer, he lost interest during December 2017 and Glosswired continued the project by himself, although he has left it at 1.2 and has no plans to continue it. Over 50 people have contributed to the kit, and it is one of the most popular kits used for creating OS mockups.

In 2020, Glosswired took down all links to the kit (except The OS Sound Kit 1.2), citing unhappiness with the community and not being proud of the kit as reasons. The website's domain has since expired.
