Preview of Monthly Rollup

Improvements and fixes

This non-security update includes improvements and fixes that were a part of KB4512488 (released August 13, 2019) and also includes these new quality improvements as a preview of the next Monthly Rollup update:

Addresses an issue in which the memory usage of LSASS continues to grow until it is necessary to restart the system.
Addresses an issue that may cause rdpdr.sys to stop responding or stop working (0x18, 0x50, 0xa, 0x27, 0x133). This issue occurs when Remote Desktop Protocol (RDP) clients use a redirected drive on the local system.
Addresses an issue that may prevent devices from starting when they start up using Preboot Execution Environment (PXE) images from Windows Deployment Services (WDS) or System Center Configuration Manager (SCCM). The error is, "Status: 0xc0000001, Info: A required device isn't connected or can't be accessed."

Known issues in this update

Symptom

Workaround

Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.

Do one of the following:

Perform the operation from a process that has administrator privilege.
Perform the operation from a node that doesn’t have CSV ownership.

Microsoft is working on a resolution and will provide an update in an upcoming release.
