Windows Rutwik is an operating system bootleg of Windows 7 made by Rutwik.
Windows Rutwik started in 2020 when 7Zeb wanted to make a custom OS, the OS was based off of Windows 7, however there are no development builds from 2020.
In 2024, the builds we're revived, and a couple were made, however most of them are lost.
On July 21, 2025, the Windows Rutwik builds did a development reset (similar to the Windows Longhorn Development Reset), starting with Build 6433 there was new changes.
