How to Activate Windows 10 Without a Product Key: A Comprehensive Guide

Windows 10 is the most popular and widely used operating system from Microsoft that offers many features and benefits for users. However, to enjoy the full functionality of Windows 10, you need to activate it with a valid product key or a digital license. Activation verifies that your copy of Windows is genuine and not used on more devices than allowed by the Microsoft Software License Terms.

If you are running Windows 10 without activation, you might be facing certain restrictions in terms of features and functionality. For example, you may not be able to personalize your desktop, access some apps and services, or receive updates and security patches. You may also see a watermark on the bottom-right corner of your screen that says “Activate Windows”.

In this article, we will show you how to activate Windows 10 without a product key using three different methods: online, via telephone, and using a batch file. These methods are legal and safe to use, as they rely on the official activation tools and keys provided by Microsoft. However, they may not work for all versions and editions of Windows 10, so you may need to purchase a new product key or license if these methods fail.

Method 1: Activate Windows 10 Online Using a Product Key

The online method is the most convenient and common way to activate Windows 10. You will need a 25-character product key that you can find in an email from whoever sold or distributed Windows to you, or on the box of the official Windows USB that you installed your system from.

To activate Windows 10 online using a product key, follow these steps:

  1. Open the Settings app on your computer. You can find it on your Start menu, or use the search or Cortana button on your taskbar to quickly open it.
  2. Select Update & Security on the left sidebar, and then click Activation on the right panel. This will open your product activation options.
  3. Click Change product key. This will allow you to enter your 25-digit product key to activate Windows on your computer. If you haven’t purchased the full version of Windows yet, you can click Go to Store here, and purchase the full version from the online Windows Store.
  4. Enter your product key to activate. Type in your 25-digit product key, and click Next to continue. Then click Activate to fully activate all of Windows’s features on your computer.
  5. Remain connected to the Internet. To ensure that your product key has not been used on another device, you must remain connected to the Internet to finish activation.

Method 2: Activate Windows 10 Via Telephone Using an Installation ID

This method can be used if you are activating an unsupported version of Windows or if you do not have an Internet connection. You will need a phone and a unique installation ID that will be generated by your computer.

To activate Windows 10 via telephone using an installation ID, follow these steps:

  1. Press ⊞ Win + R on your keyboard to open the Run dialog box. Type in slui 4 and press Enter.
  2. Choose your country or region from the drop-down menu. Click Next.
  3. Call the toll-free number on-screen. This will connect you to the Microsoft activation center.
  4. Dial the CAPTCHA number provided. As a measure against spam, only human callers are allowed to proceed to activate Windows.
  5. Enter the unique installation ID using the phone keypad. To do this, you will have to enter one group at a time. Each group is separated by spaces.
  6. Write down the confirmation ID that you will receive from the automated voice system.
  7. Enter in the confirmation ID on your computer. Then click Activate Windows. This will finish activation.

Method 3: Activate Windows 10 for Free Using a Batch File

If you don’t have a license key or you want to use Windows 10 for free, you might be interested in some methods that use batch files to activate Windows 10 without paying anything. However, these methods are not legal or official, and they may cause problems with your system or security. Use them at your own risk.

Method 1: Using a Batch File with Product Keys and KMS Server

This method involves using a batch file that contains commands to install different product keys for Windows 10 editions and then connect to a Key Management Service (KMS) server to activate them. A KMS server is a server that provides activation services for Microsoft products. However, the KMS servers used in this method are not authorized by Microsoft and may be unreliable or malicious.

To use this method, follow these steps:

  • Open Notepad on your PC.
  • Copy the code from the first web result¹ and paste it into Notepad.
  • Save the file as a batch file with the name “1click.cmd”.
  • Run the batch file as administrator by right-clicking on it and choosing “Run as administrator”.
  • Wait for the batch file to execute and activate Windows 10.
  • Restart your PC when prompted.

Method 2: Using cscript to Run slmgr.vbs Script

This method involves using cscript, a command-line tool that runs scripts written in VBScript or JScript, to run slmgr.vbs, a script that manages software licensing for Windows. This method allows you to activate Windows 10 without popups or user interaction.

To use this method, follow these steps:

  • Open Command Prompt as administrator by typing “cmd” in the search box and choosing “Run as administrator”.
  • Type the following command and press Enter:

cscript %windir%\system32\slmgr.vbs /ato

  • This command will attempt to activate Windows 10 using the current product key. If successful, you will see a message saying “Product activated successfully”.
  • You can also use other options with slmgr.vbs to check the activation status, uninstall the product key, or install a new product key. For more information, type:

cscript %windir%\system32\slmgr.vbs /?

Method 3: Using KMSPico, a Third-Party Activator

This method involves using KMSPico, a third-party activator that mimics a KMS server and activates Windows 10 and other Microsoft products. KMSPico is one of the most popular activators, but it is also considered illegal and potentially harmful by Microsoft and antivirus software.

To use this method, follow these steps:

  • Download KMSPico from its official site³.
  • Install Windows activator on your PC using the KMSPico installer.
  • Launch the installation folder and run the .exe file.
  • You will see a red switch button. Click on it.
  • Wait until the activation process is completed.
  • Restart your PC.


These are some of the methods that use batch files to activate Windows 10 for free. However, these methods are not recommended or supported by Microsoft, and they may violate their terms of service or cause damage to your system or security. The best way to activate Windows 10 is to purchase a genuine license key from Microsoft or an authorized retailer.
