How to Downgrade Windows 11 Pro to Windows 11 Home Without Data Loss

Officially, Microsoft does not support downgrading Windows 11 Pro to Windows 11 Home without a complete format and clean installation. However, there is a proven registry workaround that tricks the Windows installer into believing your system is already running Windows 11 Home, allowing you to run an in-place setup that preserves 100% of your personal files, programs, and system settings. By changing two registry values (EditionID and ProductName) in the Windows Registry Editor and running the official Windows 11 ISO setup, you can seamlessly downgrade to Home with zero data loss.

Whether you recently purchased a computer with an unlicensed Pro installation or want to switch to a more affordable genuine Windows 11 Home license, this step-by-step tutorial will guide you through the exact process safely.

1. Why Downgrade from Windows 11 Pro to Home?

Many users find themselves on Windows 11 Pro unintentionally—often after buying a refurbished PC, having an IT technician install Pro without a permanent key, or testing Pro features they no longer need. If you do not require enterprise management tools like BitLocker, Hyper-V, or Group Policy, downgrading to Windows 11 Home allows you to activate your PC legally using a standard retail key.

2. Pre-Requisites: Download the Windows 11 ISO

Before modifying the registry, you need an authentic copy of the Windows 11 installation media:

1. Visit the official Microsoft Windows 11 Download Page.
2. Scroll down to Download Windows 11 Disk Image (ISO) for x64 devices.
3. Select Windows 11 (multi-edition ISO) and choose your product language.
4. Save the .iso file directly to your Downloads or Desktop folder. Alternatively, you can follow our tutorial to create a Windows 11 bootable USB drive.

3. Step 1: Change the EditionID in Windows Registry

Windows checks your current edition string before offering the option to keep files during installation. We will change this string from Professional to Core (the internal name for Home):

1. Press Windows Key + R, type regedit, and press Enter to launch the Registry Editor.
2. Navigate to the following key path:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
3. Locate EditionID on the right pane. Double-click it and change its value from Professional to Core.
4. Locate ProductName on the right pane. Double-click it and change its value to Windows 11 Home.

4. Step 2: Run the In-Place Windows 11 Home Setup

Now that your registry reports Windows 11 Home, run the installer:

1. Right-click the downloaded Windows 11 ISO file and select Mount.
2. Open the virtual DVD drive and double-click setup.exe.
3. On the installer screen, click Change how Setup downloads updates and select Not right now (this ensures the setup proceeds smoothly offline).
4. Accept the license terms. On the “Ready to install” screen, verify that it states:
   Install Windows 11 Home and Keep personal files and apps.
5. Click Install. Your PC will restart several times over the next 15–30 minutes while rewriting the core OS packages.

5. Step 3: Activate Your Windows 11 Home License

Once the desktop loads, navigate to Settings > System > About and verify that your edition is officially Windows 11 Home. To activate your permanent license:

1. Open Settings > System > Activation.
2. Click Change product key.
3. Enter your purchased 25-character Windows 11 Home product key and click Activate.
