Method 2: Change Registry
This way is a bit complicated. Here, we will walk you through two cases about how to replace motherboard without reinstalling Windows 7 by changing the registry.
Case 1: Modify Registry before Replacing Motherboard and CPU
This method needs to be completed before you replace your motherboard and CPU. If you haven't replaced your motherboard and CPU yet, Windows can start up normally. In this case, you have to change the registry in the current working Windows before proceeding motherboard and CPU upgrade.
Step 1: Press Win + R to bring up the Run dialog, input regedit in the textbox and click OK to launch Registry Editor.

After modifying the registry, you can shut down your computer and then start installing a new motherboard and CPU. After that, your Windows OS should be able to boot normally.
This method is quite helpful for replacing the motherboard and changing the CPU without a fresh install. Please remember to complete this method before you upgrade the motherboard and CPU.
Case 2: Modify Registry Using an Offline Registry Editor after Motherboard Update
Perhaps you have replaced your motherboard and CPU but forgot to change the registry beforehand, then Windows OS failed to boot.
In this case, in addition to using MiniTool ShadowMaker to perform a universal restore (mentioned in Operation 4), you can choose to use an offline Registry Editor to modify the Windows Registry to upgrade motherboard and CPU without reinstalling Windows.
To do this, you are required to boot the non-working PC from a Windows 7 installation disc, and then start the following operations.
Step 1: After computer boot, configure the language, time and format, keyboard or input method.
Step 2: In the following screen, click Repair your computer.
Step 3: In the System Recovery Options screen, choose Command Prompt.
Step 4: In the CMD window, type regedit command and press Enter to launch Registry Editor.
Step 5: Highlight the HKEY_LOCAL_MACHINE key.
Step 6: Choose Load Hive from the File menu to load the offline registry.
Step 7: Go to the drive where Windows is installed and choose system file. Usually it is the path: C:\Windows\system32\config\system. Then click the Open button.
Step 8: Type a key name, for example, Offline.
Step 9: Go to HKEY_LOCAL_MACHINE\Offline\ControlSet001\services\msahci and double-click Start to change the value data to 0.
Step 10: Then, perform the same modification to this key:
Step 11: After finishing the modifications, highlight Offline and choose Unload Hive from the File menu to write back the changes you have made to the offline Registry.
Step 12: Restart your PC, specify the SATA mode (IDE-ATA, AHCI or RAID) according to your needs or leave the default settings in BIOS, exit BIOS, remove the Windows 7 installation disc, let the OS run properly and install required hard disk controller drivers.
By this way, you can upgrade motherboard and CPU without reinstalling Windows.
If you want to replace motherboard without reinstalling Windows 7 when it is dead, change the registry based on the actual situations.
Activate Your Windows 7 for Motherboard and CPU Update
After you finish upgrading your motherboard and CPU, you may be required to reactivate Windows. If your OS is Windows 7, there is nothing to worry about. Windows will most likely reactivate by itself. If it doesn't, call Microsoft for help.
For Windows 10, Microsoft gives a help tutorial - Reactivating Windows 10 after a hardware change. Alternatively, you can reactivate it by following the tips.
Step 1: Before the upgrade, go to the Settings tab, and change the account to a Microsoft Account rather than Local Account.
Step 2: Upgrade the motherboard & CPU. After Windows 10 boots again, it will tell Windows 10 to reactivate:
Go to Settings > Update & security > Troubleshoot > I changed hardware on this device recently.
Next, sign in your Microsoft Account again and click the Activate button. Then, Windows 10 will grab the activation key from your online Microsoft account and re-link it to your computer with its freshly-upgraded hardware.
Step 3: If you prefer a local account instead of a Microsoft account, you can change the account back.
With these three steps, you now know how to upgrade motherboard and CPU without reinstalling Windows 10, and how to reactivate the OS as well.
After finishing reading this post, you should know how to replace motherboard and CPU without reinstalling Windows 10/8/7. Follow the methods above if you need to upgrade motherboard and CPU without fresh install.
