Improvements

This security update includes quality improvements. Below is a summary of the key issues that this update addresses when you install this KB. If there are new features, it lists them as well. The bold text within the brackets indicates the item or area of the change we are documenting.

- [FrameShutdownDelay] Fixed: The browser ignores its value in the “HKLM\\SOFTWARE\\Microsoft\\Internet Explorer\\Main” registry key.

• [vmswitch] Fixed: A vmswitch triggers a stop error. This occurs when you use Load Balancing and Failover (LBFO) teaming with two virtual switches on a virtual machine (VM). In this case, one virtual switch uses single root Input/Output virtualization (SR-IOV).
  - [Collector sets] Fixed: They do not close properly when an exception occurs during startup or while the set is active. Because of this, the command to stop a collector set stops responding.
  - [Windows Kernel Vulnerable Driver Blocklist file (DriverSiPolicy.p7b)] This update adds to the list of drivers that are at risk for Bring Your Own Vulnerable Driver (BYOVD) attacks.
  - [Windows Backup] Fixed: Backup sometimes fails. This occurs when a device has an Extensible Firmware Interface (EFI) system partition (ESP).
