Microsoft has released KB4345421, a new update for Windows 10 version 1803, the April 2018 Update, yesterday evening.
The update is available through Windows Updates but users and administrators can download and install it manually as well.
The update has been published on the Microsoft Update Catalog website from where it can be downloaded to local systems. The update is available for 32-bit and 64-bit systems, ARM-based systems, and as a Windows Server 2016 version.
KB4345421 is a cumulative update for Windows 10 and Windows Server 2016; this means that you download a full update from the Microsoft Update Catalog website.
KB4345421
The update KB4345421 for Windows 10 version 1803 addresses several issues caused by updates released on the July 2018 Patch Day.
Microsoft notes that the update does not introduce new features to the operating system. Note that Microsoft may not list all changes on the Knowledgebase page as indicated by “key changes include” on that page.
- Addresses an issue that may cause some devices running network monitoring workloads to receive the 0xD1 Stop error because of a race condition after installing the July update.
- Addresses an issue with the DHCP Failover server that may cause enterprise clients to receive an invalid configuration when requesting a new IP address. This results in a loss of connectivity.
- Addresses an issue that may cause the restart of the SQL Server service to fail occasionally with the error, “Tcp port is already in use”.
- Addresses an issue that occurs when an administrator tries to stop the World Wide Web Publishing Service (W3SVC). The W3SVC remains in a “stopping” state, but cannot fully stop or it cannot be restarted.
Admins and users have reported these issues in the comment section of our July 2018 Patch Day overview ever since the updates were released by Microsoft.
Microsoft states that it is not aware of any issues with the update; this may change in the coming days when admins and users install the new update and report issues back to Microsoft. The past has shown that Microsoft’s “known issues” fails to list issues occasionally (or regularly?).
As always, if you plan to install the update make sure you create a system backup before you do so to have a restoration option. (via Deskmodder)
Should you install the update? I suggest you only do so if you are affected by one of the issues mentioned in the update’s description.
