Windows 11 gets a new “optional” update which Microsoft silently rolled out: KB5016691. Since this update has been released in the 4th week of the month, it is safe to assume that similar fixes and improvements are to be anticipated in next month’s Patch Tuesday updates.
KB5016691 was also earlier released to the Release Preview channel for the Insiders. The same update has now been flighted for the stable channel. Installing this update on the stable channel will upgrade the operating system’s build to 22000.918.
This update does not bring any new features to the operating system, probably because Microsoft is planning to release Windows 11 22H2 later this year, which will include many new features. However, this update does include a plethora of fixed and improvements.
Let us see what is update brings and then decide whether it is worth installing right now, or wait for the actual stable release next month.

- An issue that affects the automatic high dynamic range (Auto HDR) feature for cross-adapter resource scan-out (CASO)-capable GPU drivers has been addressed.
- An issue that causes Microsoft Edge to stop responding when using IE mode has been fixed. This issue also prevented you from interacting with a dialog box.
- An issue that prevents virtualized App-V Microsoft Office applications from opening or causes them to stop working entirely has been fixed.
- An issue that might cause the deployment of the Windows Hello for Business certificate to fail in certain circumstances after you reset a device is mitigated.
- Multiple issues related to USB printing have been addressed, such as:
- A printer malfunctions after you restart or reinstall it.
- Being in the wrong mode after you switch from an Internet Printing Protocol (IPP) Class Driver to an independent hardware vendor (IHV) driver.
- Experiencing bidirectional communication issues that prevent you from accessing device features.
- An issue that affects the ProjectionManager.StartProjectingAsync API has been addressed.

- A race condition that causes the Local Security Authority Subsystem Service (LSASS) to stop working on Active Directory domain controllers has been mitigated.
- An issue that affects a lookup for a nonexistent security ID (SID) from the local domain using a read-only domain controller (RODC) has been addressed. The lookup unexpectedly returned the STATUS_TRUSTED_DOMAIN_FAILURE error instead of STATUS_NONE_MAPPED or STATUS_SOME_MAPPED.
- An issue that might cause the Local Security Authority Server Service (LSASS) to leak tokens has been fixed. This issue affects devices that have installed Windows updates dated June 14, 2022, or later.
It looks like this update addresses the same issues as the one released earlier in the Release Preview channel. However, the OS builds are still different. Moreover, Microsoft has also updated the servicing stack to version 22000.910.
Since this is an optional update, Microsoft did not disclose any known issues in this flight.
Should You Update?
Since this update is previously tested in the Release Preview channel, it has already been vetted by Microsoft for any serious issues. However, the purpose of this Type D release is to test the update further and resolve any issues left before the actual Patch Tuesday update next month.
Considering these, we believe that it is safe to update to this build as long as it is not on a critical system. Installing optional updates on production environments is not the wisest of decisions.
If you plan to install this update, let us see how you can achieve that.
