Where to find your Windows activation status
Open Settings by pressing the Windows key and typing "settings", then select the Settings app. Go to System in the left sidebar, then scroll down and click About. Look for the line that says Activation. If it shows "Windows is activated", your license is active. If it shows "Activation pending" or displays an error, your system is not currently activated.
You can also check activation status from the command line if you prefer. Press Windows key + R, type cmd, and press Enter. Type the command slmgr /xpr and press Enter. A window will appear telling you whether Windows is activated and when your license expires (if applicable).
Both methods show the same information — the Settings route is simpler for most people, while the command line method works if Settings is not responding.
Key Takeaways
- Check activation status in Settings > System > About, where you will see a single line stating whether Windows is activated.
- If activation is pending or shows an error, Windows will usually attempt to activate automatically within a few days of a valid license being detected.
- An activated Windows system shows no watermark on the desktop and allows you to change wallpaper, colors, and lock screen settings without restriction.
- If your system remains unactivated after 30 days, you can still use Windows but with limited customization options and a persistent watermark.
What the activation status actually means
Activated means Windows has confirmed your license with Microsoft's servers and your system is fully licensed. You have no restrictions on features or customization. This is the normal state for systems with a valid license key.
Activation pending usually appears on new installations or after a major hardware change. Windows is waiting to contact Microsoft's servers to verify your license. This typically resolves within a few days without any action on your part, as long as your system is connected to the internet.
Not activated or an error message means Windows could not verify your license. This can happen if your license key is invalid, already used on another system, or if your system cannot reach Microsoft's activation servers. You will see a watermark in the bottom right corner of your screen that says "Activate Windows" and some customization options will be locked.
What changes when Windows is not activated
An unactivated Windows system is fully functional for everyday tasks — you can open programs, browse the web, use email, and work with documents normally. The main restrictions are cosmetic and organizational rather than functional.
You cannot change your desktop wallpaper, lock screen image, accent colors, or theme. The Settings app will show a message directing you to activate before allowing these changes. You also cannot personalize your Start menu tiles or use some accessibility features. A watermark reading "Activate Windows" appears in the bottom right corner of your desktop at all times.
After 30 days of non-activation, Windows will begin showing notifications prompting you to activate, but these can be dismissed. The system will continue to work, but the watermark remains visible and customization stays locked.
How to fix activation if it is not working
First, make sure your system is connected to the internet and has been for at least a few minutes. Windows needs to reach Microsoft's servers to verify your license. Restart your computer and check Settings > System > About again — activation often completes after a restart.
If activation still shows as pending or displays an error, open Settings > System > Troubleshoot > Other troubleshooters and look for an option related to activation or licensing. Run the troubleshooter and follow the prompts. This tool can sometimes resolve connection issues that prevent activation.
If you see an error code, write it down and search for that specific code on Microsoft's support site. Different codes point to different problems — some indicate an invalid key, others indicate a server connection issue, and some mean the key has been used too many times. The error code will tell you what step to take next.
When activation fails because of hardware changes
If you recently replaced your motherboard, hard drive, or other major components, Windows may not recognize your license. This is because Windows ties your license to your hardware configuration. When major hardware changes, Windows sees it as a different computer and may refuse to activate.
In this case, go to Settings > System > Troubleshoot > Activation and select "I changed hardware on this device recently". Windows will walk you through re-activating with your existing license key. You will need to sign in with the Microsoft account associated with your license, or have your product key ready.
If you do not have your product key and cannot remember it, you can sometimes recover it from your Microsoft account. Sign in at account.microsoft.com, go to your devices, find your Windows device, and look for the option to view or manage your license.
Understanding product keys and digital licenses
Windows licenses come in two forms: product keys (a 25-character code you enter during installation) and digital licenses (tied to your Microsoft account and hardware). If you bought Windows from a store, you have a product key. If you upgraded from an older version of Windows or bought a new computer with Windows pre-installed, you likely have a digital license.
A digital license does not require you to enter anything — Windows activates automatically when it detects your Microsoft account and recognizes your hardware. A product key must be entered in Settings > System > Activation > Change product key if you are setting up a new installation or moving Windows to different hardware.
You can see which type of license you have in Settings > System > About. If it shows a product key field, you have a product key license. If it shows only "Activation" status without a key field, you have a digital license.
What to do if you cannot activate your license
If you have a valid license but activation is not working, contact Microsoft Support. Go to support.microsoft.com, search for "Windows activation", and select the option to chat with an agent or schedule a callback. Have your product key or Microsoft account information ready.
If your license key is invalid or you do not have a license, you will need to purchase one. Windows Home licenses are sold through Microsoft's website and authorized retailers. You can also purchase a license directly from Settings > System > Activation > Go to Microsoft Store, which will open the Windows Store page where you can buy a license online.
Until you have a valid license, your system will remain unactivated. You can continue using Windows with the restrictions described above, but activation will not complete without a valid key or digital license.
Frequently Asked Questions
Can I use Windows if it is not activated?
Yes. Windows will run normally for all work and everyday tasks. The only limitations are that you cannot change your wallpaper or colors, and a watermark appears on your desktop. After 30 days, you will see periodic notifications asking you to activate, but you can dismiss them.
How long does activation usually take?
Activation usually completes within a few minutes if your system is connected to the internet. If it shows "Activation pending", wait a few days and restart your computer — it often completes automatically. If it still has not activated after a week, check your internet connection and run the activation troubleshooter.
What if I see an activation error code?
Write down the error code and search for it on Microsoft's support site. Each code points to a specific problem — some mean your key is invalid, others mean a server connection failed, and some indicate the key has been used too many times. The code will tell you what to do next.
Do I need to activate Windows every time I restart my computer?
No. Once Windows is activated, it stays activated. Restarting your computer does not change your activation status. Activation only needs to happen once per license, unless you make major hardware changes or move your license to a different device.
Can I move my Windows license to a different computer?
It depends on your license type. A digital license is tied to your Microsoft account and hardware, so moving it requires going through the hardware change process. A product key can be used on one device at a time, but you will need to deactivate it on the old device first before using it on a new one.
