General Improvements and fixes

The Key changes of these updates are as follow-

  1. They update the time zone information for Argentina, Kazakhstan, São Tomé, Príncipe and Buenos Aires.
  2. They solve the Microsoft Office Visual Basic issue which is known to create nuisance while applying registry settings on Japanese era dates. To know more, have a look at KB4469068.
  3. They also solve the issue which restricts users from enabling gan-nen support on Japanese era calendar.
  4. The Company resolve an error which primarily occur in Microsoft Access 97 database. It basically stops a requested operation when there is custom properties on Table or Column.
  5. Microsoft solves the issue which doesn’t allow users to authenticate and thus causes WAM (short for Windows Account Manager) to fail while using a TPM (short for Trusted Platform Module).
  6. They address an error which results into failing of certificates during use of CERT_RENEWAL_PROP_ID on ICertPropertyRenewal interface.
  7. They also address the bug which generate the Error code “Stop ox133” in NTFS.sys.
  8. Earlier users were not receiving all the available Windows updates using Unified Write Filter (UWF) servicing mode despite the same section is enabled. They resolve this bug as well.
  9. They fix a bug in which authentication dialog doesn’t appear when an Enterprise Web tries connecting to net.
  10. The Company addresses the issue in which a smart card sign in with credentials simply fails on Azure Active Directory i.e. AAD. using Remote Desktop Services.

Some other changes

  1. They fix an error which removes the ALLOWCLSIDS policy from the policy XML file whenever users try to run Add-SignerRule for Windows Defender Application Control.
  2. They resolve the bug which restrict users from login while using App-V client to open different apps. It also leads to account lockouts in several situations. The sole reason behind this is failing of Kerberos authentication while working to get Users information from Domain name server. You can solve this issue using following key changes under its registry-
    • Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AppV\Shared\
    • Setting: UseDcForGetUserInfo
    • Type: REG_DWORD
    • Value: Setting the following DWORD to nonzero will enable the solution.
  3. Microsoft addresses an issue that prevents App-V applications from starting and generates error “0xc0000225”. Setting the following DWORD to a non-zero number will enable the solution: “HKLM\Software\Microsoft\AppV\\MAV\Configuration\MaxAttachWaitTimeInMilliseconds”. The default is zero, the maximum is 10,000, and it limits the maximum wait time for a driver when the error occurs. For more information, see KB4494206.
  4. They resolve an issue in which the graphics device interface (GDI) DeleteObject() may cause the calling process to stop working when both of the following conditions are true:
    • The calling process is a WOW64 process that handles memory addresses larger than 2 GB.
    • The DeleteObject() is called with a device context that is compatible with a printer device context.

Known issues- KB4489888 and KB4489890

Issue #1

After updating your System with this release, some apps may stop responding due to MSXML6. This occurs only if an exception is thrown out during node operations like- moveNode(), insertBefore() and appendChild().

If there is group policy preference for IE 10 (internet explorer) settings and you edit this particular GPO (group policy object), it may cause Group Policy Editor to stop responding as well.

Sol– The Company is working on a fix to this issue and if found, they will bring the same in an upcoming release.

Issue #2

Custom URI schemes for Application Protocol handlers are now not starting the corresponding apps for local intranet as well as trusted sites on internet Explorer. This too occurs after applying this update on your System.

Sol- You should enable Protected mode in IE for local intranet and trusted sites. Follow below written steps to overcome this issue on your PC-

  1. At first navigate to, Tools > Internet options > Security.
  2. Thereafter, select Local intranet followed by Enable Protected mode under “Select a zone to view or change security settings”.
