+# Upgrading Windows 10 to Windows 11 on unsupported systems
+
+## WARNING
+
+* READ FIRST: [Microsoft: Installing Windows 11 on devices that don't meet minimum system requirements](https://support.microsoft.com/windows/installing-windows-11-on-devices-that-don-t-meet-minimum-system-requirements-0b2dc4a2-5933-4ad4-9c09-ef0a331518f1)
+
+This is not supported by Microsoft, most of the methods listed here didn't
+work for me on the first system I updated, Windows is not my primary operating
+system and my Windows was in factory reset state so it not working won't
+affect me.
+
+## What worked on Sedric
+
+Sedric has no TPM or currently supported CPU, while the health check app says
+it's only two years old (I think that is wrong).
+
+* https://gist.github.com/AveYo/c74dc774a8fb81a332b5d65613187b15
+  * It said "Downloading Windows 10", but as per comments it will really be
+    Windows 11 and the actual installation will speak of Windows 11.
+
+## Registry files here
+
+I think the first method is likely the best, but I cannot rule these working
+on another system out yet. They didn't work on my first system tried.
+
+* `00-AllowUpgradesWithUnsupportedTPMOrCPU.reg` - the official Microsoft
+  recommendation and the only one that should be used. If after reboot
+  nothing happens, maybe try the rest rebooting every failure.
+  * https://support.microsoft.com/windows/windows-11-n-asentaminen-e0edbbfb-cfc5-4011-868b-2ce77ac7c70e
+* `01-LabConfig.reg` - widely reported to work
+* `01-Setup.reg` - ^
+* `02-DevRing.reg` - after joining the Insider program, this should enforce
+  joining to Dev ring which should offer Windows 11 instantly. It may be
+  advisable to leave after successful update.
