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

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”

6.How to check the Windows license expiration date

You can see someone sell cheap Windows product keys when you search Google or Bing. But these product keys may be 1-year or 2 -year, not lifetime.

Today I will guide you how to check the Windows 11/10/8/7 license expiration date ( 1-year or lifetime)

Step 1: You go taskbar and type “cmd”

Step 2: You right-click on it and choose “Run as administrator”

Step 3: You type “slmgr/xpr” then you enter

• The machine is permanently activated: your product key is lifetime

• Volume activation will expire 12/31/2020: your product key is a year

If you want to see full license you type “slmgr.vbs /dlv“

7.If the product key has error, What should you do?

You please print the screen this error, I will try my best to help you or give you another product key or refund the payment to you

I give an example error. A customer uses Windows 10 Home but he buys wrong Windows 10 Pro key. So he needs to upgrade Windows 10 Home to Windows 10 Pro and use this key.

If you can’t use Paypal to order the product key, you can use Payoneer or Visa/Master Cards: https://cheapproductkeys.xyz/payment-method/
