Yesterday was Microsoft's Patch Tuesday for August. As usual, the company focused on fixing issues in the Windows 10 platform through cumulative updates. All versions of the OS received the patches, which also cover security issues. However, it seems to be a bug in one of the cumulative releases.
Specifically, the patch for Windows 10 Version 1607 has a bug that affects the Windows Update history.
If you are sketchy on your build numbers, version 1607 is the Anniversary Update. Considering the Creators Update is the newest Windows 10 release, many users will have moved on from 1607. Although, there are still millions of users running the Anniversary release.
The cumulative update in question is KB4034658. According to Computer World, the update wipes clean the Windows Update history. It is unclear why this is happening, or whether Microsoft will fix it.
It seems likely that once the history is wiped it is gone for good. With that in mind, if Microsoft does issue a fix, it is unlikely to restore a lost history. It is worth pointing out the company has not yet officially acknowledged this issue.
One way to avoid losing the history before updating is to take a screenshot of the history. For what it's worth, this cumulative update pushes the Anniversary Update to build number 14393.1593.
August Patch Tuesday
While the Anniversary Update release has problems, the other cumulative released for Windows 10 seem to be working well.
For users running the latest Creators Update build, here's what Microsoft fixed:
- Addressed issue where the policies provisioned using Mobile Device Management (MDM) should take precedence over policies set by provisioning packages.
- Addressed issue where the Site to Zone Assignment List group policy (GPO) was not set on machines when it was enabled.
- Addressed issue where the AppLocker rules wizard crashes when selecting accounts.
- Addressed issue where the primary computer relationship is not determined when you have a disjoint NetBIOS domain name for your DNS Name. This prevents folder redirection and roaming profiles from successfully blocking your profile or redirects folders to a non-primary computer.
- Addressed issue where an access violation in the Mobile Device Manager Enterprise feature causes stop errors.
- Security updates to Microsoft Edge, Microsoft Windows Search Component, Microsoft Scripting Engine, Microsoft Windows PDF Library, Windows Hyper-V, Windows Server, Windows kernel-mode drivers, Windows Subsystem for Linux, Windows shell, Common Log File System Driver, Internet Explorer, and the Microsoft JET Database Engine.
