This blog post will discuss finding license information for your Windows 10/11 operating system using Powershell. There are other ways to find out Windows OS license information as well, however using a Powershell script is much quicker and provides you with the results directly on the console.

In a recent blog post, I discussed 4 ways to get Windows 10/11 product key information. The Windows product key is a code you may have used to activate your Windows 10/11 Operating system.

Activating Windows OS using a legitimate product key unlocks Windows features so you can utilize the full functionality of the OS. Today, we will explore Powershell scripts that can fetch below Information about the OS from your device:

• License Name – Windows Operating system edition details
• Description – More Information about Windows edition installed on the device
• Application ID
• Product Key Channel
• License URL
• Validation URL
• Partial Product Key
• Product Key ID
• License Status
• Product Key – OEM Product key
