Hi Alex,
Experimental is the build you are
on and that Channel has not gotten
the update yet. I am also on that build
and we just have to wait.
Windows Insider Preview — Certificate Renewal (2026), not correct request?

Why my Win got this message when my Win Insider Preview is set to channel Experimental, core 26H2?
I checked Properties->Windows Update -> Insider Preview
System version is 26300.8935 26H2
Following the table I shouldn't be obliged to update my Win, since it refers only to channel Experimental, core Future Platforms, but everytime I boot my Win11 a popup tells me I do need to update it before August 11th.
Thanks

Does this apply even if I joined channel Experimental, core 26H2 (Not core Future platforms?) in your opinion?
