It’s probably because your computer has quick boot turned on which isn’t actually fully shut off. More like a deep hibernate which can still receive magic packets that can turning it on for updates and such. If it’s a work laptop it’s almost certainly because your work has set up so it wakes up when they push an update. It’s more of an issue with how your work has set up group policies. You can turn off magic packets in advanced network settings if you have admin access to your computer, which you may not if it’s a company laptop.

Are you saying spaghetti code isn’t all bad? Finally someone validates my open source projects 😅
