We"re just eight days away from Patch Tuesday, but it seems that Microsoft had to get a cumulative update out right away. Today"s update is for PCs running the Windows 10 Fall Creators Update, and it brings the build number to 16299.251.
Specifically, the update is KB4090913, and you can manually download it here. It contains the following fix:
Addresses an issue in which some USB devices and onboard devices, such as a built-in laptop camera, keyboard, or mouse, stop working. This may occur when the Windows Update servicing stack incorrectly skips installing the newer version of some critical drivers in the cumulative update and uninstalls the currently active drivers during maintenance.
There are also several known issues to be aware of:
| Symptom | Workaround |
|---|---|
| Windows Update History reports that KB4054517 failed to install because of error 0x80070643. | Even though the update was successfully installed, Windows Update incorrectly reports that the update failed to install. Select Check for Updates to verify that there are no additional updates available. You can also type About your PC in the search box on the taskbar to verify that your device is using the expected OS build. Microsoft is working on a resolution and will provide an update in an upcoming release. |
| Because of an issue that affects some versions of antivirus software, this fix applies only to computers on which the antivirus ISV updated the ALLOW REGKEY. | Contact your antivirus manufacturer to verify that their software is compatible and that they have set the following REGKEY on the computer: Key="HKEY_LOCAL_MACHINE" Subkey= "SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat" Value Name="cadca5fe-87d3-4b96-b7fb-a231484277cc" Type="REG_DWORD” Data="0x00000000” |
| After installing this update, some devices may fail to start, and return INACCESSIBLE_BOOT_DEVICE. This issue occurs when the windows update servicing stack incorrectly skips installing the newer version of some critical drivers in the cumulative update and uninstalls the currently active drivers during maintenance. | Microsoft is working on a resolution and will provide an update in an upcoming release. Workaround steps are available in KB4075150. |
| Because of an AD FS server issue that causes the WID AD FS database to become unusable after a restart, the AD FS service may fail to start. | There is no way to undo the database corruption. To return your AD FS server to a functional state, you must restore it from a backup. |
As usual, there"s no need to install the update manually. You can get it by heading over to Settings -> Update & security -> Windows Update -> Check for updates.
