How to Check If Windows Is Activated – Using Settings, slmgr, and PowerShell

Whether you’re setting up a new workstation, troubleshooting licensing issues, or auditing machines before a compliance review, knowing how to verify Windows activation status is a fundamental skill. I’ve walked countless IT admins and end users through this process over the years, and the good news is it takes about 30 seconds once you know where to look.

Let’s cover the three most reliable methods to check Windows activation — from the simplest GUI approach to command-line options that work great for scripting and remote administration.

Method 1: Check Activation Through Settings (Easiest)

This is the go-to method for most users and works identically on Windows 10 and Windows 11.

1. Press Windows + I to open Settings
2. Navigate to System > Activation
3. Look for the Activation state field

If Windows is properly activated, you’ll see “Windows is activated” along with your activation type (typically “Windows is activated with a digital license” or “Windows is activated with a digital license linked to your Microsoft account”).

If it’s not activated, you’ll see “Windows is not activated” with an error code and a troubleshoot button.

Pro tip: On Windows 11, you can also type “activation” directly into the Start menu search to jump straight to this screen.

Quick Answer

Method 2: Using slmgr (Software Licensing Management Tool)

The slmgr command has been around since Vista and remains one of the most reliable ways to check activation status — especially useful when you need more detailed information than Settings provides.

Open Command Prompt or PowerShell (regular user permissions work fine for queries), then run:

slmgr /xpr

A dialog box will pop up telling you whether the machine is permanently activated or when the activation expires. For volume license installations, you might see an expiration date for KMS activation.

For more comprehensive licensing details, try:

slmgr /dli

This displays the license name, description, partial product key, and license status. If you need the full technical breakdown (useful for troubleshooting with Microsoft support), use:

slmgr /dlv

This verbose output includes the remaining Windows rearm count, trusted time, and KMS server information if applicable.

Note: The slmgr dialogs can be slightly annoying since they pop up as separate windows rather than outputting to the console. We’ll fix that with the PowerShell method below.

Method 3: PowerShell – Best for Scripting and Remote Checks

If you manage multiple machines or want output you can actually work with programmatically, PowerShell is your friend.

Open PowerShell and run:

Get-CimInstance -ClassName SoftwareLicensingProduct | Where-Object { $_.PartialProductKey } | Select-Object Name, LicenseStatus

The LicenseStatus value tells you everything:

• 0 = Unlicensed
• 1 = Licensed (activated)
• 2 = Out-of-box grace period
• 3 = Out-of-tolerance grace period
• 4 = Non-genuine grace period
• 5 = Notification
• 6 = Extended grace

For a quick one-liner that returns human-readable output:

(Get-CimInstance -ClassName SoftwareLicensingProduct | Where-Object { $_.PartialProductKey -and $_.Name -like "*Windows*" }).LicenseStatus -eq 1

This returns True if Windows is activated, False otherwise — perfect for scripts and automation.

Checking Remote Machines

Need to verify activation on a remote computer? Assuming you have appropriate permissions and PowerShell remoting enabled:

Invoke-Command -ComputerName TARGETPC -ScriptBlock {
    Get-CimInstance -ClassName SoftwareLicensingProduct | Where-Object { $_.PartialProductKey } | Select-Object Name, LicenseStatus
}

Replace TARGETPC with the hostname or IP address.

What If Windows Isn’t Activated?

If you discover a machine that isn’t properly activated, here are your options:

• Purchase a legitimate license from an authorized Microsoft reseller
• Run the activation troubleshooter (Settings > System > Activation > Troubleshoot) if you believe the machine should be activated
• Re-enter your product key if you have one: slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
• Contact Microsoft support for hardware-change scenarios where digital license linking has broken

For organizations running volume licensing, verify your KMS server is reachable and that the machine has proper network connectivity to it.

Wrapping Up

Checking Windows activation is straightforward once you know your options. Settings works great for quick visual confirmation, slmgr provides detailed licensing information, and PowerShell gives you the flexibility to script checks across your entire environment.

If you’re managing a fleet of machines and need to ensure proper licensing across the board — or if you need to purchase Windows licenses for new deployments — feel free to reach out. As an Authorized Microsoft Reseller, we can help you get the right licensing in place without the headaches.
