- Addresses an issue that causes a VM to throw an error after creating the VM with static memory. This occurs when you enable HYPER-V and disable NUMA in the BIOS on a physical machine that has more than 64 logical processors. The error is “The data is invalid. (0x8007000D)”, and the VM fails to start.
- Addresses an issue that occurs when multiple processes are limited by rate, using job objects. This can cause various symptoms including, but not limited to, system-process CPU spikes, interrupt-time CPU spikes, high privileged time on some CPUs, and increased system or processor queue lengths.
- Addresses an issue that causes docker builds to fail with the error message “hcsshim::ImportLayer failed in Win32: The system cannot find the path specified.”
- Addresses an issue in which Windows 10 clients that authenticate to 802.1x WLAN access points fail to apply Group Policy permissions, run scripts, or retrieve roaming profiles at user logon.
