I'm building a new PC and would like to reuse the 512GB Intel 600p M.2 NVMe SSD from my current system to avoid buying another drive and having to transfer everything. The old PC has a Gigabyte B365 HD3 motherboard, an Intel i5-9400F, and Windows 10 installed on the SSD. The new system will use a B650E MAX GAMING WIFI AM5 motherboard with a Ryzen 7 7800X3D, along with a new 1TB Samsung 990 EVO Plus NVMe SSD.
Will the old M.2 drive work in the new motherboard, even though the new system is likely intended for Windows 11? I'd prefer to keep my existing files and Windows installation, though I'm willing to move to Windows 11 if necessary. I'm also wondering whether my Windows activation key will remain valid after changing the motherboard and CPU.

The old NVMe drive should be physically and electrically compatible with the new motherboard, and Windows will often boot after detecting the new hardware and installing the appropriate drivers. The first startup may take longer while it reconfigures. Motherboards aren’t limited to one particular Windows version as long as compatible drivers are available.
If the old installation was configured for legacy BIOS booting, you may need to enable the appropriate compatibility setting or convert the installation to UEFI, since newer boards generally default to UEFI. It’s also a good idea to back up important files and be prepared for a clean Windows installation if the existing setup becomes unstable after the major platform change.
Windows activation depends on the license type. A retail license can generally be transferred, provided it is only used on one computer at a time. An OEM license is technically tied to the original motherboard, although Microsoft may sometimes reactivate it for a home-user hardware upgrade. You may need to reactivate Windows after the swap.
NVMe M.2 drives use PCIe, so compatibility is usually very good across generations. The new motherboard should recognize the Intel drive, and its Windows 10 installation can potentially boot on the new system. Make sure the drive is installed in an M.2 slot that supports NVMe rather than only SATA M.2 devices.
The bigger issue is Windows support rather than hardware compatibility. Windows 10 is no longer receiving normal security support, so you’ll eventually want to upgrade to Windows 11 or use another actively supported operating system. You can keep the old drive as a secondary storage device and install Windows 11 on the new 1TB SSD if the existing installation does not boot cleanly.
That clears things up—thank you! I’ll back up my files first and check whether the current installation is using UEFI before moving the drive.
