Known issues in this update


Symptom Workaround
Because of an issue that affects some versions of antivirus software, this fix is being applied only to the computers on which the antivirus ISV have updated the ALLOW REGKEY.

This issue is resolved in KB4093118. You no longer need the following ALLOW REGKEY to detect and be offered this update: 

HKEY_LOCAL_MACHINE"Subkey="SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat\cadca5fe-87d3-4b96-b7fb-a231484277cc

The LSM.EXE process and applications that call SCardEstablishContext or SCardReleaseContext may experience a handle leak. Once the leaked handle count reaches a certain threshold, smart card-based operations fail with error "SCARD_E_NO_SERVICE". Confirm the scenario match by reviewing the handle counts for LSM.EXE and the calling processes in the process tab of Task Manager or an equivalent application.

This issue is resolved in KB4091290.

After installing KB4056897 or any other recent monthly updates, SMB servers may experience a memory leak for some scenarios. This occurs when the requested path traverses a symbolic link, mount point, or directory junction and the registry key is set to 1:  

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanManServer\Parameters\EnableEcp

This issue is resolved in KB4103718.
