Microsoft kills Secure Boot in Windows 7, stops some ASUS systems

If you are using an ASUS motherboard or bought one of their computers [or maybe you don’t know it but you have a computer with an ASUS motherboard] you may want to look out for this one.

KB3133977KB3133977 was recently reclassified from Optional to Recommended. As a recommended update, most will install it.

To protect ASUS computers against malware attacks, ASUS has enables Secure Boot by default on its motherboards. Problem is that Microsoft has stopped supporting Secure Boot with Windows 7.

KB3133977 is supposed to disable that support.

So after the next reboot, you end up with a Secure Boot Violation message.

ASUS has provided a workaround at Basically in the UEFI BIOS, you need to change the OS Type in the Boot menu to Other OS, then Save. Then verify the Platform Key (PK) State is set to Unloaded.

As usual, some of the conspiracy nuts thing this is another way for Windows 7 users to be pushed to Windows 10.
