Get the tools needed to customize Windows

Here's what you'll need to start testing and deploying devices:


Here's how we'll refer to them:

  • Technician PC: Your work PC. This PC should have at least 15GB of free space for installing the Windows Assessment and Deployment Kit (Windows ADK) and for modifying Windows images.

    We recommend using Windows 10 for this PC. The minimum requirement is Windows 7 SP1, though this requires additional tools or workarounds for tasks such as running PowerShell scripts and mounting .ISO images.

    For most tasks, you can use either an x86 or x64 PC. If you're creating x86 images, you'll need an x86-based PC (or virtual machine) for a one-time task of generating a catalog file.

  • Reference device: A test PC or tablet that represents all of the devices in a single model line; for example, the Fabrikam Notebook PC Series 1. This device must meet the Windows 10 minimum hardware requirements.

    You'll reformat this device as part of the walkthrough.


  • WinPE USB key: Must be at least 512MB and at most 32GB. This drive will be formatted, so save your data off of it first. It should not be a Windows-to-Go key or a key marked as a non-removable drive.

  • Storage USB key (USB-B): A second USB key or an external USB hard drive for storing files. Minimum free space: 8GB, using NTFS, ExFAT, or any other file system that allows files over 4GB. If your hardware allows it, use USB 3.0 keys/drives and USB 3.0 ports to speed up file copy procedures. Note, some USB 3.0 keys don't work with some USB 2.0 ports. We won't be reformatting this drive, so as long as you have enough free space, you can reuse an existing storage drive.

To use a single storage drive, see WinPE: Store or split images to deploy Windows using a single USB drive


Copy the following source files to the technician PC, rather than using external sources like network shares or removable drives. This reduces the risk of interrupting the build process from a temporary network issue or from disconnecting the USB device.

The version numbers of the Windows ADK, the Windows image you're deploying, and the languages and features you're adding must match.

This lab assumes the 64-bit architecture, so if you’re using the 32-bit version, change all mentions of x64 to x86.

  • Mount the ISO file to a drive, and note the drive letter, for example, D.

  • Copy the D:\sources\install.wim file, and save it to the local drive, in the folder: C:\Images\Win10_x64\.

Product keys

Get the default product keys for each Windows version from the Kit Guide Windows 10 Default Manufacturing Key OEM PDF, which is on the ISO with the Windows image.

Sample files: Create a deployment USB drive

  1. Format a USB Drive with the NTFS file format, name it USB-B.

    Extract USB

  2. Download the lab samples from the Microsoft download center, and extract the files to the drive.

Prepare your technician PC

Here’s how to set up your PC.

Copy the Windows image to the local drive

  1. Mount the Windows ISO file that you downloaded (Right-click the file > Mount), and note the drive letter, for example, D.

  2. In File Explorer, create a new folder (example: C:\Images\Win10_x64), and copy the Windows image (D:\sources\install.wim) file into the folder. This will help speed file creation procedures later on.

Install the Windows ADK for Windows 10

  1. If you have a previous version of the Windows Assessment and Deployment Kit (ADK), uninstall it.

  2. Download the version of the Windows ADK that matches the version of Windows that you’re installing. Run the installer.

  3. Click Next > Next > Accept to accept the defaults and to join the Customer Experience Improvement Program.

  4. Select the following tools:

    • Deployment Tools

    • Windows Preinstallation Environment (Windows PE)

    • User State Migration Tool (USMT)

    For these labs, you won't need the Windows Performance Toolkit or the Windows Assessment Toolkit. You can clear those check boxes.

  5. Click Install, and then click Yes to confirm. This may take a few minutes.

  6. When the installation is finished, click Close.
