If you have purchased a Windows product that requires telephone activation, we would like to provide you with instructions on how to proceed.
Press the + key combination (alternatively, click on the Start symbol, type CMD, and press Enter) and enter the command "slui 4" in the Run dialog.
2. A new window will open. Select the appropriate country from the drop-down menu and click on "Next".
An installation ID with nine number blocks will appear. Above it, you will find a phone number that you must call.
If you prefer to perform the telephone activation yourself, a computerized voice will instruct you to enter the number blocks using the keypad on your phone. You will then receive a confirmation ID with blocks A to H. Note down this number on a piece of paper.
Click on the "Enter Confirmation ID" button and enter the ID you just received.
Complete the activation process by clicking the "Activate Windows" button.
Done. We wish you a great experience with your product.
