How the operating system (OS) works depends on the operation of all software installed on the computer. If your Windows system is not licensed, then the operating system itself may malfunction, as well as software conflicts of applications both with the OS and with each other.
Necessary
Computer running Windows operating system, Internet access
Instructions
Step 1
Launch one of the internet browsers and go to the official Microsoft website. The link to it can be found by entering the appropriate query in the address line - you can't go wrong.
Step 2
Check for authenticity the operating system installed on your computer by clicking the "Check now" button on the website page. During the verification process, Microsoft will match your computer's hardware profile with a special symbolic key that is listed in the certificate of authenticity. After the end of the authentication, a message about the results of the verification will appear. If a genuine copy of Windows is installed on the computer, a Windows verification success message appears. In the case of a counterfeit operating system, you will see a message about the impossibility of confirmation with recommendations for the user, as well as an offer to purchase a licensed operating system.
