But W7 has gone EOL, whereas W10 and the non-cloud subscription WS products have yet to reach EOL and hence should be in receipt of security updates.
I also like that whilst W11 might have been receiving the HVCI updates, it has served no real purpose as the functionality hasn't been turned on by default. A situation that will change with W11 22H2. So we can expect as the W11 22H2 update gets rolled out, users will be reporting problems...
