Windows 10 May Hotfix (KB5013942) is out – here’s what’s new and what’s broken

Today is the second Tuesday of the month, which means it’s Patch Tuesday again. As such, today Microsoft is releasing the February 2022 Monthly Security Update (also referred to as “Release B”) for Windows 10 for the latest versions 20H2, 21H1, and 21H2. The new updates are distributed under the number KB5013942, which increases the number of builds to 19042.1706, 19043.1706 and 19044.1706.

You can find separate download links for the new update on the Microsoft website. Updating the Catalog at this link here .

The main highlight of the release are the security updates for Windows 10, and as usual, the Redmond-based company has also listed known issues in the update, which is always handy. Here are the symptoms and the corresponding workarounds:

Symptom Workaround

Devices with Windows installations created from custom offline media or a custom ISO image may have Microsoft Edge Legacy removed by this update, but not automatically replaced with the new Microsoft Edge. This issue only occurs if custom offline media or ISO images are created by streaming this update to an image without first installing the March 29, 2021 or later offline servicing stack update (SSU).

Note. Devices that connect directly to Windows Update to receive updates are not affected. This includes devices that use Windows Update for Business. Any device that connects to Windows Update should always get the latest SSUs and the latest cumulative update (LCU) without any further action.

To avoid this issue, be sure to first insert an SSU released on March 29, 2021 or later into a custom offline media or ISO image before inserting the LCU. To do this with the merged SSU and LCU packages currently in use for Windows 10 version 20H2 and Windows 10 version 2004, you will need to extract the SSU from the merged package. To extract the SSU, follow these steps:

  1. Extract the cab from msu via this command line (using the package for KB5000842 as an example): expand Windows10.0-KB5000842-x64.msu /f:Windows10.0-KB5000842-x64.cab

  2. Extract the SSU from the previously extracted cab file using this command line: expand Windows10.0-KB5000842-x64.cab /f:*

  3. After that, you will have an SSU cab, named SSU-19041.903-x64.cab in this example. First add this file to your offline image and then to the LCU.

If you’ve already encountered this issue when installing the OS using affected custom media, you can mitigate it by installing the new Microsoft Edge directly. If you need to widely deploy the new Microsoft Edge for Business, see Download and deploy Microsoft Edge for Business.

After installing the June 21, 2021 update (KB5003690), some devices cannot install new updates, such as the July 6, 2021 update (KB5004945) or later. You will receive an error message “PSFX_E_MATCHING_BINARY_MISSING”. For more information and a workaround, see KB5005322.

Recovery discs (CDs or DVDs) created using the Backup and Restore (Windows 7) application in Control Panel may not start after Windows Updates released on January 11, 2022 or later versions of Windows are installed on an affected version of Windows .

This issue does not affect recovery discs created with Backup and Restore (Windows 7) on devices that have Windows updates released before January 11, 2022, and should start as expected.

Note. Third-party backup or restore applications are currently not known to be affected by this issue.

We are working on a solution and will provide an update in the next release.
We’re getting reports that the Snip & Sketch app might not take a screenshot or open with a keyboard shortcut (Windows key + Shift + S). This issue occurs after installing update KB5010342 (February 8, 2022) and later updates. We are currently investigating and will let you know when more information becomes available.
