To change Windows 10 Enterprise LTSC to Windows 10 Pro, you typically have two paths: a clean installation or a workaround using a product key. While Microsoft officially recommends a clean install for this downgrade, community methods allow for an in-place transition if you have a valid Pro license. Method 1: Clean Installation (Recommended)

This is the only officially supported method and ensures a stable system without lingering Enterprise policies.

Back Up Data: All files will be deleted. Save them to an external drive or cloud service like OneDrive.

Create Installation Media: Use the Windows 10 Media Creation Tool to create a bootable USB drive.

Boot from USB: Restart your PC and boot from the USB (usually by pressing F12 or F2 during startup). Install Windows 10 Pro: Select Install Now.

When prompted for a product key, enter your Windows 10 Pro key or click "I don't have a product key" and select Windows 10 Pro from the list.

Choose Custom: Install Windows only (advanced) and format your primary drive. Method 2: In-Place Change via Product Key how to change windows 10 enterprise ltsc to windows 10 pro

If you have a valid Windows 10 Pro retail key, you can sometimes "downgrade" without a full reinstall.

Disconnect Internet: This prevents the system from checking activation servers immediately, which can sometimes block the edition switch.

Navigate to Activation: Go to Settings > Update & Security > Activation.

Enter Generic Pro Key: Click Change product key and enter the generic Windows 10 Pro key: VK7JG-NPHTM-C97JM-9MPGT-3V66T.

Note: This key will not activate Windows; it only triggers the edition change.

Restart and Activate: Once the system reboots and identifies as Windows 10 Pro, go back to Activation settings and enter your genuine Pro product key to activate the license. Method 3: Registry Modification (Advanced)

If Method 2 fails, advanced users use the Media Creation Tool with a registry tweak to fool the installer into allowing an "upgrade" to Pro.

Download Windows 10 ISO: Use the Media Creation Tool to download a standard Windows 10 ISO.

Modify Registry: Open PowerShell as Administrator and change the registry values for EditionID and ProductName to "Professional" and "Windows 10 Pro" to match the target version.

Run Setup: Mount the ISO and run setup.exe. The installer should now allow you to select Keep personal files and apps. Pros: Tries to keep all apps and settings

To change Windows 10 Enterprise LTSC to Windows 10 Pro, you generally have two paths: a registry-based "in-place" downgrade or a clean installation. Microsoft does not officially support a direct in-place downgrade from LTSC to Pro.  Method 1: Registry Downgrade (No Reinstall) 

This unofficial method "tricks" Windows into thinking it is already a Pro version so you can run a Pro repair/install over it while keeping your files. 

Backup Data: Always back up important files before editing the registry. Edit Registry: Press Win + R, type regedit, and hit Enter.

Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion. Change EditionID to Pro (it likely says EnterpriseS).

Change ProductName to Windows 10 Pro (it likely says Windows 10 Enterprise LTSC).

Repeat: Make the same changes at HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion. Run Pro Setup:

Download the Windows 10 Media Creation Tool from the official Microsoft website.

Run the tool to create an ISO or USB, then launch setup.exe from within your current Windows session. Select the option to Keep personal files and apps.  Method 2: Generic Key Method 

In some cases, simply changing the product key to a generic Pro key can trigger the edition change, though this is less reliable for LTSC.
