Microsoft have released an update to Windows 10 April 2018 Update just a week after patch Tuesday. The update KB4345421 is a cumulative update taking the build number to 17134.166.
The changes to this build are fixes to networking, SQL server and web publishing servers:
- 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.
