Here's what's new for Windows 7 and 8.1 this Patch Tuesday

It's that time of the month again when Microsoft unleashes an array of updates to all of the supported versions of Windows. This includes, of course, multiple versions of Windows 10, but also Windows 7 and 8.1. As usual, each OS gets two different kinds of updates - a monthly rollup and a security-only update.

For Windows 8.1, the monthly rollup update is KB4530702, and it can be downloaded manually from here. It comes with a single change:

Security updates to Windows Virtualization, Windows Kernel, Windows Peripherals, the Microsoft Scripting Engine, and Windows Server.

The security-only update is KB4530730, and it can be downloaded manually from here. The changelog is very similar, except there's no update for the Microsoft Scripting Engine. Both updates have the same known issue, which has been around for months:

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

As for Windows 7, the monthly rollup update is KB4530734, and it can be downloaded manually from here. The changelog is very similar to the one for Windows 8.1:

Security updates to Windows Input and Composition, Windows Virtualization, Windows Kernel, Windows Peripherals, the Microsoft Scripting Engine, and Windows Server.

The security-only update is KB4530692 and it can be downloaded manually here. It has a similar changelog, but just like Windows 8.1, it doesn't include updates to the Microsoft Scripting Engine. Neither update has any known issues.

It's worth noting that this is the second last update you will ever get unless you're using a business machine ad your company opts to pay for extended security updates. Windows 7 support will end on January 15, after which, no more updates will be released. You may want to consider upgrading to a newer version of Windows to stay secure.
