How to use product key to activate Windows 7/8/10

Posted on by admin

Hi you. I have some notes you should know:

  1. The product key I sell only activates Windows. It can’t be used to download/setup/upgrade Windows.
  2. The product key for Windows 10 Pro can’t use to activate Windows 10 Pro N/ Pro Education/ Pro for Workstations and other editions of Windows 10. So you need to buy the right product key for your Windows you use.

So in this article I will guide you:

  1. How to download Windows 7/8/10/11 without product key
  2. How to install Windows 7/8/10/11 without product key
  3. How to find out which edition of Windows 7/8/10/11 you are running (Windows 10 Pro/ Pro N/ Home…)
  4. How to upgrade/downgrade between Windows 10/11 editions
  5. How to use the product key to activate Windows 7/8/10/11
  6. How to check the Windows license expiration date (Lifetime or 1-year)
  7. If the product key has error, What should you do?
  8. When will you receive the product key?

Because I live in Vietnam, so when you order, it may be midnight in my country. Please wait. After 1 day you don’t receive the product key, you can send an email to me: [email protected] or pm my skype: [email protected]

Note: Because a buyer said he didn’t receive the product key although I sent the product key to his email 2 times (he uses Hotmail, I use Gmail). So I add my skype to Contact Us page.

To buy product key, you click “Add to card” => “View card” => “Check out”
