Log:
[NTOSKRNL]: Implement MiCheckSecuredVad and stop whining about not supporting
SEC_NO_CHANGE, cleaning up the log.
[NTOSKRNL]: Kill a bunch of now-useless DPRINT1s in Mm, significantly cleaning up the
log.
[HIVES/MSI]: .NET needs InstallRoot, not InstallDir. Kills millions of DPRINT1s, thus
cleaning up the log.
