Fake Microsoft Windows License Expiry Scam
Pop-up alerts or emails claim a Windows license has expired or is invalid and direct users to call a number or pay through a fraudulent site, ultimately leading to credential theft or fraudulent payments.

Last reviewed: 7 June 2026
Microsoft Windows is licensed software, and a small proportion of Windows users do encounter genuine activation issues — particularly after hardware changes. This real scenario provides scammers with a plausible pretext for fake 'license expired' or 'Windows is not activated' alerts that push users toward fraudulent payment pages or support calls.
Windows itself displays clear activation status notifications within Settings — not through browser pop-ups or emails sent to users. However, users who are not familiar with the genuine activation interface may not know this, making browser-based fake alerts convincing.
The financial risk from this scam includes both the direct payment for a fictitious license renewal and the credential or banking access that may be harvested when remote support is provided.
How this scam works on the Microsoft brand
Windows displays genuine activation status under Settings > System > Activation. A legitimately unlicensed copy of Windows shows a watermark in the corner of the desktop and displays a notification in Settings. Microsoft does not send browser pop-ups or cold emails demanding payment to reactivate a Windows installation.
Fake license expiry alerts appear as browser pop-ups — sometimes triggering a fake Windows-style dialog box with a Microsoft logo — or as emails claiming an automatic renewal for a product key was processed and payment is needed. A phone number is provided for 'activation support'.
Calling the number connects the victim to fraudsters who either walk them to a fake Microsoft payment portal to enter card details for a 'new license key', or guide them through installing remote access software and subsequently stage the classic overpayment refund scam.
Common red flags
- A browser pop-up claims your Windows license has expired and provides a phone number to call
- An email invoices you for a Windows license renewal you do not recall authorising
- You are asked to call a support number to 'reactivate' Windows — Microsoft does not use phone activation for consumer Windows
- The support agent asks you to install remote access software to fix the license issue
- The message does not appear in Settings > System > Activation, where genuine activation issues are displayed
- The license key purchase link does not point to microsoft.com
How to protect yourself
- Check your Windows activation status in Settings > System > Activation — this is the only authoritative source
- Purchase Windows licenses only at microsoft.com or from authorised retailers
- Close and ignore any browser pop-up claiming a Windows license issue — close the browser tab instead of calling the number
- Microsoft's product activation for consumer Windows is online and automatic — it does not require phone calls
- If you legitimately need a Windows license, buy from microsoft.com/en-us/windows/get-windows
How to report it
- Report tech support scams to Microsoft at microsoft.com/reportascam
- Forward suspicious billing emails to [email protected]
- File a report with the FTC at reportfraud.ftc.gov (US) or Action Fraud actionfraud.police.uk (UK)
- If money was paid, contact your bank immediately and also report to the FBI IC3 at ic3.gov (US)
Frequently asked questions
How do I check my real Windows activation status?
Open Settings > System > Activation on your Windows PC. If Windows is properly activated, you will see 'Windows is activated' with the activation method. If there is a genuine activation issue, this settings page — not a browser pop-up or email — is where you will see it.
Does my Windows license ever expire?
Retail and OEM Windows licenses are perpetual — they do not expire. Microsoft 365 subscriptions that include Windows have renewal cycles, but these are managed at account.microsoft.com, not through browser alerts. Windows Insider builds and evaluation copies have limited lifetimes, but these apply only to specific technical scenarios.
I paid for a Windows license via a pop-up. Can I get a refund?
Contact your bank or card issuer immediately to dispute the charge. The vendor you paid is likely fraudulent. File a report with your consumer protection agency. If remote access was granted, check your device for any software installed during the session and change passwords for accounts accessed on the device.
