I managed getting Extended Kernel working on Windows 2000 RTM!
It can trick software into believing the operating system is Windows XP (NT version 5.1) or higher to bypass version checks.
Installing this kernel is highly technical and usually requires a specific order of updates to avoid system failure: . Update Rollup 1 (Official). Unofficial Update Rollup (UURollup) v11 by BlackWingCat. Cert_Updater to handle modern root certificates. Known Limitations and Risks
