Do I Need To Reinstall Windows With New Motherboard And CPU?

Getting a new motherboard and a CPU is probably one of the most exciting things that you can upgrade your PC with besides a new GPU. However, as exciting as it is, there is that one thing no one likes to do, and it is to ask themselves “Do I need to reinstall Windows…again?”. But do you really? Well, let’s find out.

In a hurry? Well, the quick answer this time is that you can, the better question is if you actually should avoid reinstalling windows. In order to avoid reinstalling, you simply have to de-activate your key from the current windows, as it is bound to your current hardware, kind of. Once you do so and implement the new components, simply re-activate it. We still suggest a full reinstall for the best performance.

Do I Have To Reinstall Windows With A New Motherboard?

Reinstalling Windows is something nobody is a fan of, as it can take quite a while to do so, especially if you do not happen to own an SSD. 

One of the most common questions towards technicians is “If I buy a new motherboard do I have to reinstall windows?”, and while a lot of technicians are going to tell you that you should reinstall Windows, you do not really have to do it, even if it is probably easier and faster.

However, keep in mind that there are a couple of beginners mistakes, that unfortunately, even some technicians who have been in business for years tend to forget now and then. That mistake is the part where your Windows key is tied to your current “unique hardware profile”.

What does that mean? Well, every PC uses that profile in order to load all the correct drivers as you turn on your computer and make the Windows boot up. If you happen to change a component before you inform Windows about those changes, it will find an error in something called “signature verification”.

What is signature verification? Whenever Windows is installed, it will be attached to your motherboard. If you do something crucial such as to replace motherboard, for example, Windows will not be able to identify that signature, and it will request a reinstall.

So, is the answer to your question “Do I need to reinstall windows with new mobo?” a yes? Not really, if you happen to prepare your current Windows for the new motherboard with new drivers.

Those drivers can either be found online, but it is much safer to simply install them over the disc you receive in the box of your new motherboard.

Another thing that you will probably have to do with the change of hardware is to re-activate your Windows. Before you re-activate the windows, it is important that you check what kind of license do you have.

There are 3 different licenses, OEM, Retail, and Volume. OEM is the one you do not want to have, as it is tied up to the motherboard and cannot be changed to a different one.

In order to check which license you have, enter the Command Prompt, press win key + R, type cmd, and press ok. Then simply type slmgr –dli, and it will tell you what kind of license do you have, or if you have one at all.

If you happen to have a digital license, follow these steps:

  • Sign in to your PC with an administrator account.
  • Select the Start button and open the Settings menu.
  • From the Settings control panel, select Update & Security, then Activation.
  • From the Activation menu, select Troubleshoot.
  • Click any option that says there was a recent hardware change on your device, then select next.
  • Provide your Microsoft Account login details and check the box that states, “This is the device I’m using right now.”
  • Select Activate.

In case you do not have the digital license, you can use these steps instead:

  • Sign in to your PC’s administrator account.
  • Click the Start button, and then select Settings.
  • From the Settings control panel, select Update & Security.
  • Select Activation.
  • Select Go To Store. This will redirect you to the Microsoft Store, where you can buy a new license.
