We had the question for AIX a while ago and it was more difficult because the version for AIX is a different implementation. But for Windows and Linux there is an official support statement as well. My customer sent me a different link not showing Domino 11 support. But my contact had the correct link: https://success.trendmicro.com/solution/1056583 Not having anti-virus or backup supported for a new Domino version, can be a big road blocked for upgrades. In this case, Trend did already do the verification.

This is awesome news! When I updated this week to Windows 10 Pro 2004, I looked into what's new. WSL2 got some updates and there is a new Windows Sanbox, which is also pretty cool to test stuff. You can enable it and start it just like an app. This is similar to starting a Linux desktop like Ubuntu. WSL2 is around for a while but I never looked into it. The what's new and the Sandbox made me look into it. Once you enabled WSL2 and downloaded one of the distributions form the Microsoft store (Ubuntu in my case), you can really run Linux on your Windows machine.
