KB4487006 Known Issues

1. Startup Issues in Specific Laptops

Specific Lenovo and Fujitsu laptops that currently have less than 8 GB RAM may face startup issues. The bug is created as a result of KB4467691 installation.

One of the easiest ways to resolve the issue is restarting your machine with the help of Unified Extensible Firmware Interface (UEFI). Make sure to disable Secure Boot before restarting the device. 

2.  Cluster Service Start Fail

If the “Minimum Password Length” of the group policy uses more than 14 characters then the users can face cluster service start fail error. The following error message is displayed to the user “2245 (NERR_PasswordTooShort)”. The installation of  KB4467684 triggers the error. 

Microsoft is currently working to resolve the issue and the workaround is expected to be available in the coming weeks. Till now the company suggests the users to set the default minimum password length policy to equals to or less than 14 characters.

3. IE 11 Authentication Issues

Some authentication issues are reported in Internet Explorer 11 right after the installation of IE11. As soon as the same account is used by two or more users for various concurrent login sessions on the same Windows Server machine. 

Microsoft recommends the users to create unique user accounts. Moreover, multiple RDP sessions should be disabled for each user account.

System Center Virtual Machine Manager (SCVMM) fails to manage the logical switches that have been deployed on the host that is managed by SCVMM. Also, a stop error is raised in vfpext.sysif you fail to follow the best practices. 

A quick workaround is to access the affected host machine to run mofcomp files for running two mof files named as Scvmmswitchportsettings.mof and VMMDHCPSvr.mof. Microsoft recommends that users can avoid a stop error by following the best practices.

Download KB4487011/KB4487006 for Windows 10

The KB4487011/KB4487006 patch can be automatically downloaded through the Settings menu. If you have not yet received the update you need to open the Settings menu by pressing Win+I. Now you need to navigate to Update & Security >>Windows Update >> Check for updates. 

You can enhance the consistency of the update process by installing the latest servicing stack update (SSU) just before installing the LCU KB4487011. 

Microsoft has followed its tradition to specify third Tuesday of the month for the release of the non-security cumulative update. Although these updates are termed as non-security, it is yet not clear that either security components are included in the update or not.
