Frequently Asked Questions
Can I get a refund directly from Microsoft if I bought a fake product key?
No, Microsoft does not issue refunds for software or product keys purchased from unauthorized third-party sellers. You must seek a refund through the marketplace where you made the purchase or dispute the charge with your bank or credit card company.
What are the common signs of counterfeit Microsoft software?
Common warning signs include unusually low prices, receiving only a product key via email without a physical certificate of authenticity (COA), being sold a 'Volume License' or 'OEM' key meant for businesses or manufacturers, and the software failing to activate or displaying a 'non-genuine' error message.
Is it dangerous to install pirated Microsoft software?
Yes, installing pirated software is highly risky. Counterfeit software is frequently modified by malicious actors to include malware, spyware, and ransomware, which can steal your personal data, track your online activity, and severely damage your computer.
