How can I replace an existing win 7 old os version with an OS licensed to win 7

I have a win 7 64 bit pre-installed operating system in my laptop, and I want to replace it with a professional an another win 7 64 bit version. so is this possible or how can I replace my older version with a new operating system version os.

Is the old copy on the laptop of the same edition of Windows 7 Professional or is - this another edition (for example, Home Premium, Starter or Home Basic)?

If its anothere Home Premium, Starter or Home Basic edition, you can use the Windows 7 Professional key and upgrade to upgrade to Windows 7 Professional.

If this is the same Windows 7 Professional edition and all you want to do is license swap, follow these steps:

Press Windows key + R

Type: slui.exe 3

Press enter on your keyboard

Enter your new product key and click next to activate Windows 7 Professional.

If the license for Windows 7 Professional, you have access to is a retail version update or complete, you can use the product key and the Express upgrade from Windows 7 Starter/home Basique/Familiale Premium to Windows 7 Professional. First of all, check that the edition of Windows 7, you are upgrading is already enabled (if it isn't, you will encounter complications and that you might start all by performing a clean installation). Click Start, type Anytime Upgrade, click on the option enter a key, enter the key of Windows 7 Professional on demand, click Next, wait while checking the key, accept the license agreement, click on upgrade, wait while the software upgrades, (it may take 10 minutes or more depending on the if updates are required) your computer restarts automatically, after the reboot, Windows 7 will notify you updating the computer, the computer will restart once more automatically and will be completed the upgrade, a window will appear notifying the upgrade was successful and your computer is ready to use, click Close, you should be upgraded to Windows 7 Professional your files, programs and settings retained.
