hello

like @[DSD]DukeNukem notifified on the guide thread, one futur possible issue will be the change done on beta atm with the store ui
https://steamhost.cn/news/app/593110/view/500579345320904590
can't realy remember what was the issue under xp with store change, but i've remember some issues with steamui.dll

and yes it won't be an issue with client using vxkex if you decide to stay on w7

so wait and see
the use of zstd is annoying but mostly affect new games and updates so it's still can be handled with depotdownloader or steamcmd easily ( not all games have frequent update ...may be greenlight more than others - no real clue here , just my point of view .
