You have to activate your newly installed Windows 8 in 30 days since the first system login. Do not neglect it! If you don't do it in time, you'll receive a message that your software is illegal.
1. Internet activation
In case you choose to use online activation, you can do it quickly and easily.
- Open the Activation window of Windows 8 / 8.1 by going to “Settings”, choosing the option “Control panel” and then – the “System” icon.
- Click on: Windows activation.
- In field “Product Key” type down the code of Windows 8 / 8.1 and then follow the instructions.
If online activation fails, you can do the activation by the phone.
2. Telephone activation
If Windows won’t activate online, there is always the possibility to activate it with the automatic telephone system.
The telephone activation window for Windows 8 / 8.1 can be opened in the following way: open the “Run” console by pressing Win + R on your keyboard, and then type “slui 4”.
- Choose your country from the countries list and follow the instructions.
- Call the shown telephone number – the whole process will be done by the automatic system.
- Type down the installation ID which will be shown in activation windows by the phone keyboard.
- Wait for the confirmation ID key to be generated.
- Type down the ID to the fields from A to G and click “activate”.
If this activation also failed, it is possible, that you have wrong version of Windows installed on your computer, which is not compatible with your product key (ex. Home instead of Professional).
