Windows 21 (L)

For other uses, see Windows 21 (disambiguation).
Windows 21  (codenamed Proxima) was the twenty-first major version of Windows. A relatively minor update compared to Windows 20, Windows 21 was mostly about refining the Zenith Kernel, stabilizing the operating system, and bringing much-requested features.
Windows 21's main feature was the brand-new HFD S file support. HFD II massively improved upon HFCc and in addition. HFD S was the first file system that ditched support for SSD's, requiring either MCD's or DNA.
Another major change was the introduction of a brand-new "Glance" View in the desktop which shows key information about a user's device right upon start-up and in Settings. It also includes News, Important Information, and more.
Windows 21 was the very first version of Windows to use the Windows Early Access Program, the successor to the Windows Insider Program.
== History ==
The new version of the Zenith Kernel was first unveiled in Microsoft Build 2063, Windows Unity appeared in that activity, too. Microsoft promised Windows Unity would be released in 2064, but Microsoft wasn't really sure because Windows Unity was not quite finished. In 2064, Microsoft still had a lot of work left to be done. Finally, Microsoft launched it on March 28, 2064. Windows 21 was a huge hit as soon as it was launched and eventually became one of the most popular versions of Windows.
