Question Does anybody know if indeed SAC can be turned on without reinstalling Windows?

Please provide comments and solutions that are helpful to the author of this topic.
Sometime SAC blocks the installer when freshly released, then allow it after days or weeks, as with media player classic.
Sometimes it blocks the installer even if old enough, as the case with peazip.

Sometimes it blocks the installer, but allows the installed app to launch; here turning off SAC is useful to bypass installation block.
Sometimes it blocks both the installer and the installed app after installation; turning off SAC will permit installation, but after turning it on again, launching app will be blocked.
I fail to realise what problems MS has with Peazip . SAC should allow it since it’s fairly old.
