Microsoft Toolkit for Windows 10 LTSC: Step-by-Step Activation Guide

Before You Begin: Important Notes
⚠ 1. Only use Microsoft Toolkit if you own a legitimate license but need to re-activate.
⚠ 2. Download only from trusted sources (fake versions may contain malware).
⚠ 3. Disable Windows Defender & Antivirus temporarily (they may block the tool).
⚠ 4. Windows 10 LTSC requires a Volume License (KMS) key for activation.

Step 1: Download Microsoft Toolkit
Download MS Toolkit latest version from a reliable source (e.g., MyDigitalLife forums).

Extract the ZIP file to a folder.

Step 2: Install KMS Client Key (If Needed)
If your system doesn’t already have a KMS key installed:

Open Command Prompt as Administrator.

Enter the following command for Windows 10 LTSC 2019/2021:

cmd

Download
slmgr /ipk M7XTQ-FN8P6-TTKYV-9D4CC-J462D
(Replace with your LTSC version’s key if different.)

Press Enter.

Step 3: Run Microsoft Toolkit
Open the extracted Microsoft Toolkit folder.

Right-click Microsoft Toolkit.exe → Run as Administrator.

If Windows Defender blocks it, click More Info → Run Anyway.

Step 4: Activate Windows 10 LTSC
In Microsoft Toolkit, go to the Windows tab.

Click “EZ-Activator” (recommended for automatic activation).

OR manually click:

Install KMS License → Install AutoKMS.

Wait for the process to complete (should take < 1 minute).

A success message will appear: "Product activated successfully."

Step 5: Verify Activation
Open Command Prompt (Admin) and run:

cmd

Download
slmgr /xpr
This checks if Windows is permanently activated.

Alternatively, go to:
Settings → Update & Security → Activation.
