How to Check If Your Windows License Is Genuine
Worried your Windows copy might not be genuine? Learn 5 quick methods to verify your Windows 10 or 11 license is authentic and properly activated.
## How to Check If Your Windows License Is Genuine
Whether you bought a PC second-hand, received a key from a colleague, or purchased from an unfamiliar reseller, verifying your Windows license is genuine takes just a few minutes. Here are five reliable methods.
## Method 1: Settings App (Quickest)
1. Press `Windows + I` to open Settings
2. Go to **System > Activation**
3. Look for the activation status:
| Status | Meaning |
|---|---|
| "Windows is activated with a digital license" | Genuine, linked to hardware |
| "Windows is activated with a digital license linked to your Microsoft account" | Genuine, linked to account (best) |
| "Windows is activated" | Genuine, activated with product key |
| "Windows is not activated" | Not activated — may not be genuine |
| "Windows reported that no genuine Windows was found" | Not genuine |
If you see "activated," your copy is genuine and properly licensed.
## Method 2: Command Line (Detailed)
Open Command Prompt as administrator and run:
```
slmgr /xpr
```
This shows when your license expires:
- **"The machine is permanently activated"** — Genuine, perpetual license
- **"Windows is in Notification mode"** — Not activated
- A date — Temporary or evaluation license
For more detail:
```
slmgr /dli
```
This shows:
- License name (e.g., "Windows 11 Pro")
- Description (RETAIL, OEM_DM, or VOLUME_MAK channel)
- License status (Licensed, Notification, etc.)
- Partial product key (last 5 characters)
## Method 3: System Information
1. Press `Windows + R`
2. Type `msinfo32` and press Enter
3. Look for:
- **OS Name** — Confirms your Windows edition
- **Windows Directory** — Should be `C:\WINDOWS`
This does not directly confirm licensing but shows if Windows is properly installed.
## Method 4: Microsoft Genuine Advantage (Online)
1. Open Microsoft Edge or Chrome
2. Go to `https://www.microsoft.com/genuine/validate`
3. Follow the prompts to validate your installation
Note: This tool may not be available in all regions.
## Method 5: PowerShell (Technical)
Open PowerShell as administrator:
```powershell
Get-CimInstance -ClassName SoftwareLicensingProduct | Where-Object {$_.PartialProductKey} | Select-Object Name, Description, LicenseStatus
```
**LicenseStatus values**:
- 0 = Unlicensed
- 1 = Licensed (genuine)
- 2 = OOBGrace (grace period)
- 3 = OOTGrace (out of tolerance)
- 4 = NonGenuineGrace
- 5 = Notification (not genuine)
- 6 = ExtendedGrace
A status of **1** confirms your Windows is genuinely licensed.
## Signs Your Windows May Not Be Genuine
Watch for these warning signs:
### Visual Indicators
- **Watermark** in the bottom-right corner: "Activate Windows — Go to Settings to activate Windows"
- **Black desktop background** that resets after changing
- **Personalization settings locked** — Cannot change wallpaper, colors, or lock screen
### Behavioral Indicators
- Persistent activation reminders
- Windows Update fails or is limited
- Some Microsoft Store apps refuse to install
- "Your Windows license will expire soon" notifications
## What to Do If Windows Is Not Genuine
### Scenario 1: You Have a Key But It Won't Activate
Follow our [activation troubleshooting guide](/en/blog/windows-activation-troubleshooting-guide) to resolve specific error codes.
### Scenario 2: You Never Had a Key
Purchase a genuine license:
- [Windows 11 Professional](/en/products/windows-11-professional-2) — Full features, BitLocker, Remote Desktop
- [Windows 11 Home](/en/products/microsoft-windows-11-home) — Core features, more affordable
Distivo keys activate instantly on Microsoft servers, confirming legitimacy.
### Scenario 3: You Bought a Key That Got Blocked
If you purchased from an unauthorized source and the key was revoked, the only fix is a new legitimate key. Buy from established resellers with money-back guarantees.

### Scenario 4: You Bought a Pre-Owned PC
Pre-owned PCs often have OEM licenses tied to the hardware. If the seller reinstalled a different edition or the key was modified, you may need a fresh license.
## Why Genuine Matters
Running non-genuine Windows carries real risks:
1. **Security**: You may miss critical security updates
2. **Stability**: Non-genuine copies may behave unpredictably
3. **Malware**: Cracked versions often contain embedded malware
4. **Legal**: Using unlicensed software violates copyright law
5. **Support**: Microsoft will not provide support for non-genuine copies
## Protect Your Investment
Once you confirm your Windows is genuine:
1. **Link to Microsoft account**: Settings > System > Activation — ensures you can reactivate after hardware changes
2. **Save your product key**: Store in a password manager
3. **Keep purchase receipt**: Proof of purchase from [Distivo](/) or other reseller
This protects your license for the lifetime of the software. Genuine licenses from Distivo come with instant activation, full Microsoft update access, and lifetime validity.
