R 4.1.0 was released before Windows 11, but even in R-devel, 
sessionInfo() reports "Windows 10" on "Windows 11". The problem is that 
the information comes from win.version()/GetVersionEx() and, as also 
documented in ?win.version, this may return "compatibility version".

With the already released versions of R and current R-devel, one can 
tell Windows 11 from the build number (your 22621 is Windows 11 22H2, 
22000 is Windows 11 21H2).

Thanks for spotting and reporting this.
