  • Fixed a problem where the rendering for items no longer works.

Fixed a problem that delays the loading of many unsigned DNS (Domain Name System) zones related to the DNSSEC (Domain Name System Security Extensions) function. This problem occurs after configuring the following registry settings:

Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameter

Setting: EnableFastLoadUnsignedZones activate


Value: a value of 1 activates the characteristic. A value of 0 disables the function.

Restart the operating system or DNS server after changing the registry values.

KB4499177 Known problems

Like all other versions, KB4499177 has some known problems. Microsoft has recognized the fact that the cluster service may not start. The error occurs when more than 14 characters are defined as the minimum password length.

In addition, a strange error can affect devices running Windows Server 2016 with Hyper-V enabled. The problem occurs if you reboot your system after upgrading your system.

In this case, you may encounter the error 0xC0210000 and switch to Bitlocker recovery mode.

Download the update

Microsoft strongly recommends that you install the latest service stack update (SSU) for your operating system before installing the latest cumulative update (LCU). SSUs improve the reliability of the update process to minimize potential problems during the installation of the LCU.
