Microsoft isn’t terrible when it comes to providing support for older versions of its operating system. The Windows maker recently pushed Patch Tuesday update to users running Windows 7 and Windows 8.1. As you know, Patch Tuesday doesn’t bring any new features and is all about fixing bugs and improving the overall performance. The same goes for this update.

If you are running Windows 8.1 and Windows Server 2012 R2, then you get the KB4499151 update. It brings various fixes.

  • Provides protections against a new subclass of speculative execution side-channel vulnerabilities, known as Microarchitectural Data Sampling, for 64-Bit (x64) versions of Windows (CVE-2018-11091, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130). Use the registry settings as described in the Windows Client and Windows Server articles. (These registry settings are enabled by default for Windows Client OS editions, but disabled by default for Windows Server OS editions).
  • Addresses an issue that may cause “Error 1309” while installing or uninstalling certain types of .msi and .msp files on a virtual drive.
  • Addresses an issue that prevents the Microsoft Visual Studio Simulator from starting.
  • Adds “uk.gov” into the HTTP Strict Transport Security Top Level Domains (HSTS TLD) for Internet Explorer and Microsoft Edge.
  • Addresses an issue that may cause the text, layout, or cell size to become narrower or wider than expected in Microsoft Excel when using the MS UI Gothic or MS PGothic fonts.
  • Security updates to Windows App Platform and Frameworks, Microsoft Graphics Component, Windows Storage and Filesystems, Windows Cryptography, Windows Datacenter Networking, Windows Wireless Networking, Windows Kernel, and the Microsoft JET Database Engine.

Don’t expect the update to be flawless as it comes with the following issues. Good news is you can fix them.

SymptomWorkaround
After installing this update, there may be issues using the Preboot Execution Environment (PXE) to start a device from a Windows Deployment Services (WDS) server configured to use Variable Window Extension. This may cause the connection to the WDS server to terminate prematurely while downloading the image. This issue does not affect clients or devices that are not using Variable Window Extension.To mitigate the issue, disable the Variable Window Extension on WDS server using one of the following options:

Option 1:
Open an Administrator Command prompt and type the following:

Wdsutil /Set-TransportServer /EnableTftpVariableWindowExtension:No

Option 2:
Use the Windows Deployment Services UI.

  1. Open Windows Deployment Services from Windows Administrative Tools.
  2. Expand Servers and right-click a WDS server.
  3. Open its properties and clear the Enable Variable Window Extension box on the TFTP tab.

Option 3:
Set the following registry value to 0:

“HKLM\System\CurrentControlSet\Services\ WDSServer\Providers\WDSTFTP\ EnableVariableWindowExtension”.

Restart the WDSServer service after disabling the Variable Window Extension.

Microsoft is working on a resolution and will provide an update in an upcoming release.

Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.Do one of the following:

  • Perform the operation from a process that has administrator privilege.
  • Perform the operation from a node that doesn’t have CSV ownership.
