Hi DaSven,
I'm not sure if you're actually still using Windows 10 1607, as that is where your link is pointing to. If you look at https://support.microsoft.com/en-us/topic/october-11-2022-kb5018410-os-builds-19042-2130-19043-2130-and-19044-2130-6390f057-28ca-43d3-92ce-f4b79a8378fd (the link for Win 10 21H2 and I think also some older releases), it indirectly points to the fix being included: "This security update includes improvements that were a part of update https://support.microsoft.com/en-us/topic/september-20-2022-kb5017380-os-builds-19042-2075-19043-2075-and-19044-2075-preview-59ab550c-105e-4481-b440-c37f07bf7897(released September 20, 2022)."
I haven't been able to test it yet, but I am quite hopeful that this will solve this issue.
I don't know anything about the PAC enforcement issue, though.
