Yeah it's somehow tried to update my PC to 24H2 this last month, but failed each time luckily for me I guess , since other's seem to be having so many problems with 24H2!
Anyways, found out from this page there is way to stop it using group policy editor which seems safer than hacking the registry to stop it until it's more stable or Microsoft fixes it.
Microsoft begins auto updating PCs to Windows 11 24H2 (forced download phase)
So whoever posted on here that u need to manually push button in windows update to upgrade was definitely wrong!
