One Windows user reported that he experienced font issues following the installation of KB4489868. He explained the problem as follows:

Windows Update installed KB4489868 overnight and now screen fonts have changed and there are severe rendering issues making some text unreadable. I have reset the Font Cache and turned off Clear Type but the problem remains.

Known Issues

Microsoft has listed some known errors in KB4489868, KB4489886, as well as KB4489871 and KB4489882.

1. Applications fail to respond

Your Windows applications might stop responding following the installation of the KB4489868, KB4489886, KB4489871, KB4489882 updates.

The error is caused by MSXML6. A resolution to the bug is currently under process and Microsoft promises to provide an update in an upcoming release.

2. System Center Virtual Machine Manager (SCVMM) bug

The installation of the KB4489882 update also triggers an issue related to the host machines that are currently being managed by SCVMM. As it fails to manage and enumerate the deployed logical switches.

Furthermore, vfpext.sys might encounter a stop error in case the user is not following the best practices.

Microsoft suggests a workaround to the SCVMM stating that you need to run mofcomp on these mof files Scvmmswitchportsettings.mof and VMMDHCPSvr.mof. Secondly, the issue with vfpext.sys can be corrected if you patch by following best practices.

3. IE 11 authentication issues

The installation of the KB4489882 update might trigger authentication issues for IE 10. The issue arises if the same account is being used by two or more users on a Windows Server system.

Some of the issues that you might face after the installation are:

Keyboard shortcuts fail to work
Zero or empty location and cache size
File download issues
Credential prompts bugs
Webpage loading issues

Microsoft stated that if you are using a Windows Server machine, the problem can be resolved by creating a unique user account. Furthermore, you also need to disable multiple RDP sessions for an account.

This is a temporary workaround, and Microsoft has promised to release a bug fix the next Windows Update.

4. Cluster service fails to start

The cluster service does not start following the installation of KB4467684. If the users configured the Minimum Password Length of the group policy with more than 14 characters, you might encounter the error “2245 (NERR_PasswordTooShort)”.

Microsoft said that a temporary solution to fix the problem is to set a value of less than or equal to 14 characters as the minimum password length.
