If you look at your calendars today, you may notice that it"s the second Tuesday of August, and that means it"s time for this month"s Patch Tuesday from Microsoft. As usual, every supported version of Windows is getting updates, and that includes Windows 8.1. Windows 7 is no longer support for most users, but if you"re paying for Extended Security Updates (ESU), you can still get updates for a few more years.
As usual, there are two types of updates going out - a monthly rollup update and a security-only update. The monthly rollup updates are usually installed automatically on supported devices, but the security-only updates need to be downloaded manually.
For Windows 8.1, the monthly rollup update is KB4571703, and it can be downloaded manually here. Here"s what"s new:
- Addresses an issue that prevents you from installing some .msi apps. This occurs when a device is managed by a Group Policy that redirects the AppData folder to a network folder.
- Addresses an issue in Universal Windows Platform (UWP) apps that allows single sign-on authentication when an app does not have the Enterprise Authentication capability. With the release of CVE-2020-1509, UWP applications might begin prompting the user for credentials.
- Addresses an issue in Microsoft Edge IE Mode when opening multiple documents from a SharePoint site.
- Addresses an issue in Microsoft Edge IE Mode that occurs when you browse using anchor links.
- Addresses an issue with loading Browser Helper Objects in Microsoft Edge IE Mode.
- Addresses an issue where certain applications that rely on the JScript Scripting Engine become unresponsive under load.
- Security updates to Windows App Platform and Frameworks, Windows Graphics, Windows Media, Windows Shell, Windows Cloud Infrastructure, Windows Authentication, Windows Kernel, Windows Hybrid Cloud Networking, Windows Peripherals, Windows Network Security and Containers, Windows Storage and Filesystems, Windows File Server and Clustering, Windows Hybrid Storage Services, Windows SQL components, Microsoft Scripting Engine, and Windows Remote Desktop.
There is a known issue with this release, and it"s similar to what we"ve seen in a few previous updates:
| 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:
Microsoft is working on a resolution and will provide an update in an upcoming release. |
As for the security-only update, it"s KB4571723, and you can download it manually here. It only includes the security updates mentioned in the monthly rollup above. The known issue is also the same.
Turning to Windows 7, which is only supported for paying ESU customers, the monthly rollup update is KB4571729, and it can be downloaded manually here. It includes the following improvements and fixes:
- Addresses an issue that prevents you from installing some .msi apps. This occurs when a device is managed by a Group Policy that redirects the AppData folder to a network folder.
- Addresses an issue in Microsoft Edge IE Mode when opening multiple documents from a SharePoint site.
- Addresses an issue in Microsoft Edge IE Mode that occurs when you browse using anchor links.
- Addresses an issue with loading Browser Helper Objects in Microsoft Edge IE Mode.
- Addresses an issue where certain applications that rely on the JScript Scripting Engine become unresponsive under load.
- Security updates to Windows App Platform and Frameworks, Windows Graphics, Windows Media, Windows Cloud Infrastructure, Windows Authentication, Windows Kernel, Windows Hybrid Cloud Networking, Windows Peripherals, Windows Storage and Filesystems, Windows Network Security and Containers, Windows File Server and Clustering, Windows Hybrid Storage Services, Microsoft Scripting Engine, and Windows SQL components.
The single known issue is the same one as what"s listed above for Windows 8.1.
Finally, the security-only update for Windows 7 is KB4571719, and you can download it manually here. As you"d expect, it includes the same security fixes as the monthly rollup, but nothing else. The known issue is also the same.
