Overview of motherboard upgrade
I would like to upgrade the motherboard and CPU of my computer, which runs Windows 10. However, I would prefer to avoid reinstalling the operating system. The OS is installed to an M.2 NVMe drive on an AM3+ socket motherboard, and I will be upgrading to an AM4 socket motherboard.
Are you happy with how your PC's motherboard and CPU are performing? Maybe they're not up to speed anymore, causing issues with your Windows 10 system. You might be thinking about upgrading your PC's motherboard or CPU. But, you might wonder, can you do this without having to reinstall Windows 10? Will changing the motherboard and CPU mean reinstalling Windows?
This is a common concern for many users. While reinstalling Windows 10 isn't impossible, it's a hassle that most people would rather avoid. It involves reinstalling the OS, setting up system preferences again, reinstalling all your essential apps, and transferring back any data lost during the process. Additionally, you might need to reactivate some programs after the reinstall.
Under such circumstances, effective tricks for easy & safe hardware upgrades appear to be particularly important. Here in this post, we compiled some related information you may be concerned, about and three methods to help you know how to upgrade the motherboard and how to successfully replace motherboard and CPU without reinstalling Windows.
Can I upgrade motherboard and CPU without reinstalling Windows?
The answer is yes, it is possible. Upgrading the motherboard and CPU could bring you faster speed, better performance, the support for latest components, and also a new problem - can you keep the Windows installation while upgrading?
It actually won't take much time to complete a fresh install. The real trouble is, that you have to reinstall or activate those installed programs, retrieve personal files, re-configure system settings, etc.
And if you try to replace the motherboard and CPU without reinstalling, Windows 10/8/7 and older systems like Windows XP will most likely fail to boot, because they lack the drivers required to boot Windows after replacing major hardware.
However, it doesn't mean that there is no way left. It can be a little tricky but still easier than reinstalling Windows. So, in the following content, you will get to know the step-by-step instructions and preparations on how to upgrade the motherboard and CPU. Please read on.
Will Windows 11/10/8/7 stay activated after replacing the motherboard?
First, you want to know if your Windows version will get auto-activated, which will save you a lot of trouble reinstalling it after replacing the motherboard.
There are three types of Windows license keys, OEM, Retail, and Volume. A retail license is the one you purchase from a local store or online retailer, an OEM license is preinstalled on a new computer by the manufacturer, and a Volume license is distributed in bulk to large organizations.
Generally, a Retail or Volume license will get automatically activated when connecting to the Internet. However, an OEM key is locked to the original hardware, and cannot be transferred to a new motherboard. In this case, you may need to purchase a new key.
*Even if you are using a Retail key, there are chances that you encounter activation problems and need to contact Microsoft support for further troubleshooting.
How to check your license type
To check your license key, right-click on My Computer or This PC in Windows 10 and select Properties, then scroll down to the bottom of the screen and view the Product ID. If you see OEM in the second group, then it is an OEM license key. Otherwise, it is retail or volume.
If your computer is pre-installed with Windows 10/8/7, usually it is OEM key. If you bought your license from Microsoft, it is a retail key. Volume keys are purchased by large companies or organizations.
Methods for hardware upgrade without reinstallation

Windows 11/10 won't boot after motherboard upgrade
If your Windows 11/10 won't boot after upgrading the motherboard, it could be due to a mismatch in boot modes. This often happens when the original motherboard uses Legacy BIOS mode, but the new one is set to UEFI. To troubleshoot this issue, restart your computer and access the BIOS settings. Navigate to the Boot menu and adjust the boot mode priority to match the configuration of your new motherboard.
For instance, if your original setup was Legacy BIOS and the new one is UEFI, set UEFI as the alternate boot mode. By making this adjustment, you can resolve the booting problem and ensure smooth operation of your system.
