You unfortunately can't run newer containers than the host OS :(, just user older ones. And if you use mismatching containers the startup gets slower because it switches to use full virtualization rather than containers. I think we need to switch to use full VMs rather than containers. The performance of the windows containers is just atrocious (build times on a local VM with the same number of cores is 1/2 of what we see in CI, test times 1/3), they're slow to start due to pulling all files and decompressing them, and they're fragile. I've asked Bilal (CCed) to work on generating both containers and images. Greetings, Andres Freund
