Is IIS supported in Windows 11 OS?

Hi @robert protsman ,

Thanks for the details.

The page not listing Windows 11 isn't a statement that IIS is unsupported there. The note at the bottom of that IIS lifecycle page says IIS "is a component of the Windows operating system and follows the same lifecycle" so its support dates come from the OS it's installed on, not from a separate IIS entry. The version rows listed there are illustrative rather than a complete list, and I can see they currently stop at Windows 10.

The same model applies to .NET Framework, which is also a Windows component: "Components receive the same support as their parent products" (.NET Framework support policy). Worth having on hand if you want the inheritance rule stated plainly somewhere.

So for traceability, the chain would be the IIS lifecycle note, then the lifecycle page for your Windows 11 edition:

• Windows 11 Home and Pro — 24 months of servicing per version
• Windows 11 Enterprise and Education — 36 months per version

Both are In Support today. The Windows Lifecycle FAQ states those servicing lengths as policy if you need wording rather than just a dates table.

I wasn't able to find a Microsoft page that lists "IIS on Windows 11" with its own dates. The dated line you can point to is the one for your edition and feature update.

Hope this helps! If the explanation and the information I provided were helpful, I would greatly appreciate it if you could follow this guidance so others with the same problem can benefit as well. Thank you.
