Windows 10/11 Professional is the edition for people who outgrow the Home version: BitLocker drive encryption, remote desktop, domain join, sandbox and Hyper-V. Everything familiar for games and work apps stays in place, with broader security and management settings on top. The product is an activation key: the seller sends it digitally and you enter it in the Windows activation settings on one computer.

What you get

  • An activation key for Windows 10/11 Professional on one computer.
  • A retail licence type as stated by the seller.
  • Compatibility with both 32-bit and 64-bit builds, in any system language.
  • No regional binding: the key can be used from any country.
  • Seller support for activation questions.

Important conditions

  • The key is delivered digitally only — no stickers, boxes or scans.
  • The licence is meant for home use; companies need a corporate licensing channel.
  • The seller does not guarantee the key with third-party Windows images — install from a Microsoft distribution.
  • The listing names both Windows 10 and Windows 11 — confirm the target version with the seller before paying.
  • The key and support come from a third-party seller; refunds are not offered.

Before you pay, check

  • That you need the Professional edition rather than Home.
  • That the PC meets the requirements: 1–2 GB of RAM and 16–20 GB of free disk space.
  • That the system will be installed from a Microsoft distribution, not a custom image.
  • The seller's description, warranty and terms on the payment page.
