I am personally not happy about that at all but my choice doesn't get any support. Not even registering Windows and turning off s-mode is possible without an account or with severe hacks that do involve deactivating secure boot anyway.

Microsoft is the security flaw here, they were even deemed a threat to national security in the US.

It is a complete circus and it lessens security compared to your average Windows 7 MBR installation while it was supported.

Microsoft forcing you to register to deactivate their presents pretty clearly line out their motivation here.
