Phone Activation Guide.

  1. Press Win keys (Windows window key, usually next to space) + R to open Run and type: SLUI 4 and click OK . (Note that there is a space between SLUI and 4.)
  2. Select Brazil and click Next.
  3. Call the 800 number to contact the Microsoft Product Activation Center . You will be taken through an automated menu where you will have to answer some questions about the product you are trying to activate (Windows 10), if you have already activated it (No) and if you have a product key (Yes).
  4. The automated system will now describe the Internet activation process for you. Simply wait for it to complete. At the end, the system will ask if you still need help. Say “Yes” and then you will be taken to a human operator .
  5. The operator will ask for confirmation which product you are trying to activate (Windows 10) and then ask if you have an Installation ID (Yes - it's on the same screen as the phone number you called).
  6. The operator will then ask you to read this number. I've found that you can read to them relatively quickly and they follow along really well; and if you speak clearly, you usually only have to read it once.
  7. The operator will take you back to the automated phone system, which after a few brief instructions will read your confirmation ID for you. Once the human operator calls back the automated system, click on “Enter Confirmation ID” and enter the numbers when they are read to you.
  8. After entering the Confirmation ID , you can click Activate Windows and if your product key is valid and the numbers were entered correctly, you're good to go.
