How To Activate Microsoft Windows 10

Ever since its launch on July 29, users of Microsoft Corporation’s Windows 10 have been flocking to Microsoft Forums and Reddit complaining of issues without the activation mechanism. Users were met with a variety of errors, including the famed Error ‘0xC004C003’, which usually occurs after a clean installation of Windows. Before continuing to debug the process, here are a few useful tips, as published in The International Business Times UK:

  1. As long as you’ve updated to Windows 10 from a legitimate Windows 8 and 7.1 install, the OS install process won’t prompt you for a product key. Users with pirated copies of the OS aren’t eligible for the free upgrade.
  2. Users who’ve performed a clean install without a Windows 10 key, will have to either purchase a new license from Microsoft, or start over from a legitimate Windows 7 or 8.1 installation.
  3.  If you’re being presented with error messages such as (0XC004E003, 0x8007000D, 0x8007232b or 0x8007007B), it’s most likely due to the heavy load on Microsoft’s activations server, which apparently haven’t been sized in anticipation of the extremely large volume of activation requests. As long as you’ve upgraded from a valid Windows 8 or 7.1 installation, don’t fret, as Windows 10 will automatically activate eventually.

How To Perform A Clean Windows 10 Install

It’s not possible to activate Windows 10 without purchasing a new key if you’re doing a clean install from scratch. In order to perform a clean install, you’ll need to start with a legitimate Windows 7 or 8.1 installation, update to Windows 10, and then initiate the Windows 10 clean install. This way, the key will be preserved from the previous installation. From the company’s official blog: “Windows 10 handles keys differently. When you upgrade to Windows 10 via Windows Update from Windows 8.1 or Windows 7, the process registers your computer’s hardware, and qualifying OS with a Microsoft Product Activation Server. The device is then considered a Windows 10 device. Subsequently anytime you re-install (or clean install) the installation checks with those servers, finds the unique installation ID and produces the validation.”

How to Force Activation

Step 1: Bring up the Start Menu and search for Command Prompt. Right-click it and select Run as administrator from the context menu.

Step 2: In the Command Prompt, type the text: “slmgr.vbs –rearm” (without the quotes) and press Enter to execute.

Step 3: Close the Command Prompt window and reboot your PC.
