## Step 1: Download and install ADK
## Step 2: Download CU
- Download and install the **Windows Assessment and Deployment Kit (Windows ADK)** from [Download and install the Windows ADK](windows-hardware/get-started/adk-install).
- Download and install the **Windows PE add-on for the Windows ADK** from [Download and install the Windows ADK](windows-hardware/get-started/adk-install). Make sure to download and install both components.
- It's strongly recommended to download and install the latest version of the ADK.
- When installing the Windows ADK, it's only necessary to install the **Deployment Tools**.
## Step 2: Download cumulative update (CU)
- Go to the [Microsoft Update Catalog](https://catalog.update.microsoft.com/) site and search for the latest cumulative update for the version of Windows that matches the version of Windows PE that was downloaded in [Step 1](#step-1-download-and-install-adk) or the version of the Windows PE boot image that will be updated.
- When searching the [Microsoft Update Catalog](https://catalog.update.microsoft.com/) site, use the search term `"<year>-<month> cumulative update for windows <x>"` where `year` is the four digit current year, `<month>` is the two digit current month, and `<x>` is the version of Windows that Windows PE is based on. For example, to search for the latest cumulative update for Windows 11 in July 2023, use the search term `"2023-07 cumulative update for windows 11"`. If the cumulative update hasn't been released yet for the current month, then search on the previous month.
- Once the cumulative update has been found, download the appropriate version for the version and architecture of Windows that matches the Windows PE boot image. For example, if the version of the Windows PE boot image is Windows 11 22H2 64-bit, then download the **Cumulative Update for Windows 11 Version 22H2 for x64-based Systems" version of the update.
- Store the downloaded cumulative update in a known location for later use.
## Step 3: Backup existing boot image
Before modifying the desired boot image, make a backup copy of the boot image being modified. For example,
- For the boot image included with the **Windows PE add-on for the Windows ADK**, the boot image is located at `C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\en-us\winpe.wim`.
- For the boot image included with Microsoft Configuration Manager, the boot image is located at `<ConfigMgr_Install_Directory>\OSD\boot\x64\boot.wim`
