**Symptom**| **Workaround**
—|—
Devices with Windows installations created from custom offline media or custom ISO image might have [Microsoft Edge Legacy]() removed by this update, but not automatically replaced by the new Microsoft Edge. This issue is only encountered when custom offline media or ISO images are created by slipstreaming this update into the image without having first installed the standalone servicing stack update (SSU) released March 29, 2021 or later.**Note **Devices that connect directly to Windows Update to receive updates are not affected. This includes devices using Windows Update for Business. Any device connecting to Windows Update should always receive the latest versions of the SSU and latest cumulative update (LCU) without any extra steps. | To avoid this issue, be sure to first slipstream the SSU released March 29, 2021 or later into the custom offline media or ISO image before slipstreaming the LCU. To do this with the combined SSU and LCU packages now used for Windows 10, version 20H2 and Windows 10, version 2004, you will need to extract the SSU from the combined package. Use the following steps to extract the SSU:
1. Extract the cab from the 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 <destination path>**
2. Extract the SSU from the previously extracted cab via this command line: **expand Windows10.0-KB5000842-x64.cab /f:* <destination path>**
3. You will then have the SSU cab, in this example named **SSU-19041.903-x64.cab**. Slipstream this file into your offline image first, then the LCU.
If you have already encountered this issue by installing the OS using affected custom media, you can mitigate it by directly installing the [new Microsoft Edge](). If you need to broadly deploy the new Microsoft Edge for business, see [Download and deploy Microsoft Edge for business]().
## How to get this update
**Before installing this update**Microsoft now combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). For general information about SSUs, see [Servicing stack updates]() and [Servicing Stack Updates (SSU): Frequently Asked Questions]().Prerequisite:Based on your installation scenario, choose one of the following:
1. For offline OS image servicing:If your image does not have the March 22, 2022 (KB5011543) or later LCU, you **must **install the special standalone May 10, 2022 SSU (KB5014032) before installing this update.
2. For Windows Server Update Services (WSUS) deployment or when installing the standalone package from Microsoft Update Catalog: If your devices do not have the May 11, 2021 (KB5003173) or later LCU, you **must **install the special standalone August 10, 2021 SSU (KB5005260) before installing this update.
