Known Issues for KB5009543
There may be issues installing Microsoft Edge Legacy on devices with custom offline media or custom ISO images. These devices are not automatically replaced by the updated version of Microsoft Edge. As a result, this problem may occur when you incorporate the update into a custom offline media file.
To resolve this problem, slipstream the LCU to the offline media before you slipstream the SSU in March 2021. This can be done using the SSU file found in the combined LCU and SSU package now used for Windows 10 versions 20H2 and 2004.
After installing the updated version KB5003690 (June 21, 2021), some devices are unable to install new updates. It includes the July 6, 2021 update (KB5004945) and later updates. The error message you will receive will be “PSFX_E_MATCHING_BINARY_MISSING”.
Microsoft is working on a solution to this problem.
Installing this update will affect your ability to connect to remote desktops in untrusted domains. At this point, you may see the message “Your credentials did not work. The credentials that were used to connect to [device name] did not work. Please enter new credentials.” and “The login attempt failed.” in red.
You can fix this problem by using Known Issue Rollback (KIR). It may take 24 hours for the resolution to be propagated automatically to non-managed devices such as personal devices.
