- Addresses an issue in Gdi32full.dll that causes an application to stop responding.
- Addresses a gradual memory leak in LSASS.exe on systems that have cached logon enabled. This issue mainly affects servers that process many interactive logon requests, such as web servers.
- Addresses an issue that causes Lightweight Directory Access Protocol (LDAP) client applications to stop responding for at least 30 seconds when many LDAP queries are requested through multiple connections. This occurs because of a race condition in wldap32.dll. You must install this update on the LDAP client that calls wldap32.dll.
- Addresses an issue that may prevent Cluster Aware Update from restarting nodes when a cluster's credentials are reset. Cluster Aware Update must restart nodes after installing an update. The error is the following:
”Failed to restart "NODENAME": (ClusterUpdateException) Failed to restart "NODENAME": (Win32Exception) The user name or password is incorrect.”
- Addresses an issue that may cause Microsoft Cluster Shared Volumes File Systems (CSVFS) to stop working under certain conditions.
- Addresses an issue with setting up a Storage Replica in a Scale-Out File Server with a Storage Spaces Direct cluster. Using Test-SRTopology to query multiple volumes when the Primary DNS suffix is different than the domain name may cause the query to fail with a null reference exception in GetPartitionInStorageNodeByAccessPath.
- Addresses an issue that may cause error 0x7E to occur when adding a node to an Exchange Database Availability Group server.
- Addresses an issue that causes slow screen refresh rates when an application creates and destroys many child windows.
- Addresses an issue that causes connection requests to the Remote Desktop Session Host (RDSH) servers in the deployment to fail. This issue occurs because of a deadlock in the Connection Broker.
- Addresses an issue that occasionally causes a PostScript printer to use the wrong font.
- Addresses an issue that fails to enumerate devices that have 64-bit base address registers and are assigned to virtual machines. This issue also prevents Windows from detecting these devices. This issue occurs on hosts that have the Hyper-V role enabled.
