Buy a Windows XP product key for Windows XP Professional or Windows XP Home Edition. Each key is a 25-character retail license for one PC, delivered instantly by email, with activation help from our support team.
Choose Your Windows XP Edition
- Windows XP Pro license key: for business software, domain networks, Remote Desktop hosting, file encryption (EFS) and advanced permissions.
- Windows XP Home retail key: for a simple single-user PC, retro gaming or basic legacy apps.
Before You Buy a Windows XP Key
- Match the edition: a Pro key only works with Windows XP Professional media, and a Home key only with Home Edition media.
- Use retail installation media: retail keys aren't accepted by OEM recovery discs or Volume License (VLK) media. This is the most common reason setup says a key is invalid.
- Activation: activate with the built-in Activation Wizard. If online activation doesn't complete, use the telephone option and our Get Confirmation ID tool.
- Security: Microsoft ended Windows XP support in April 2014. Use XP for legacy software, devices or virtual machines, and keep it off the open internet where possible.
Need a Modern Windows Instead?
For everyday use, browsing and current software, choose Windows 11 or Windows 10 keys, which still receive security updates.
