Development[edit | edit source]
The Windows 11 development started in October 2020. Separated into two project: Sun Valley witch was meant for new UI/UX, and Cobalt witch was meant for public releases (rs_prerelease and co_release). To access full UI/UX on SV branches we need to have: Fire Steel > Cherry Hill > Sun Valley; Internal Tool > Experience Packages > New UX. Cobalt public branches did not have any new UI/UX and branding but still have a lot of changes over Windows 10.
