> Braindead regulation.

Only because OP didn't give the full story. Microsoft wanted to close direct access to the kernel. AV companies complained to regulators in the EU. The EU asked Microsoft if they were willing to maintain access to replacement functionality and to stick to using that functionality for its own separately sold AV products. Microsoft said no, and instead of fighting, just let Windows wither on the vine with full kernel access for all the bozos. Crowdstrike was inevitable.
