CrowdStrike’s Falcon software uses a special driver that allows it to run at a lower level than most apps so it can detect threats across a Windows system. Microsoft tried to restrict third parties from accessing the kernel in Windows Vista in 2006 but was met with pushback from cybersecurity vendors and EU regulators. However, Apple was able to lock down its macOS operating system in 2020 so that developers could no longer get access to the kernel.
Now, it looks like Microsoft wants to reopen the conversations around restricting kernel-level access inside Windows.
microsoft could get away with this monopoly accusations by opening up official read-only APIs for that, so you can have antiviruses use it and have a proper procedure for user to give consent for the antivirus to have access to said API.
I agree, all they need to make sure is for their own tool to have the same access as everyone else.
