If you don't do regular major version upgrades than windows keeps piling up layers upon layers of minor updates just in case some programs might require specific old version of some system component.
That's what WinSxS folder is for, if it's too big it's not safe to clean manually but it will be cleaned if you upgrade to newer major version (for example 23h2 to 24h2 etc) even in-place upgrade without wipe will help.
