Extended Kernel
This page tracks all the extended kernel projects.
Windows XP[edit]
There is an Extended Kernel for Windows XP called One-Core API: https://github.com/Skulltrail192/One-Core-API-Binaries/
Windows Vista[edit]
Vista has an Extended kernel.
Windows 2000[edit]
BlackWingCat has made an extended Kernel for Windows 2000. It can run Mypal and 360 Chrome allowing Youtube and other modern sites to run.
Windows 98/ME[edit]
Windows 98 has an extended kernel but it has gotten harder to set up in recent years. The unicows download is broken in the installer and must be installed manually. Also many updates have to be installed. But if all updates are followed Firefox 52 and Mypal can be run if an SSE2 processor is being used. Unfortunately, Windows 98 virtualization is broken on Ryzen and Intel Ice Lake and newer processors and 86box doesn't support SSE2.
