You may deactivate the license on the old PC and activate it on a new one. There is no limit on the number of transfers, but the license can only be active on one PC at a time.
When you activate Windows, Microsoft’s servers compute a (not a simple serial number but a composite fingerprint). That hash is stored alongside your product key. During re-activation, the server compares the current hardware hash to the stored one. If they differ beyond a certain threshold, activation fails. windows license transfer
If you need to move Windows to new hardware and your current license is OEM, you have two honest options: buy a new retail license for the new PC, or keep the old PC as-is and use the new one unactivated (with cosmetic limitations only). You may deactivate the license on the old

However, you are not transferring a file or a product key alone—you are transferring a software license grant , which is a legal and technical construct.

Windows 7/8 Free Upgrade to Windows 10/11 If you upgraded for free from an OEM Win7/8 license, the resulting Win10/11 license inherits the original OEM binding —meaning it’s not transferable. If you upgraded from a retail Win7/8 license, the Win10/11 license remains retail and transferable. 3. Technical Mechanism of License Binding Microsoft uses three main systems to tie a license to hardware:
If you signed in with a Microsoft account, the license is stored in the cloud under your account. Transfer is done via the Activation Troubleshooter. C.
