Not like that, it doesn’t.

I’ve never heard of someone using bcdedit to change a boot flag, so a Bluetooth adapter will behave.

The lock screen problem I’ve seen myself a while back. At least in my case, I did not have permissions to the session manager config file, and the gui tool did not account for that. But I think I had to install the tool from the repo. It wasn’t part of the base install.

The menu problem could be a Kubuntu or early plasma issue. Either way, not something I’ve ever seen in Windows.
