How to Transfer Your Windows 10 License to Another Computer
If you purchased a windows 10 retail licence and want to transfer to new computer, I will show you how to safely deactivate the windows 10 licence product key and the transfer to a new system and activate it.
Open command prompt as administrator by typing cmd in search.
Type following commands.
slmgr -dli (This will tell you the type of key you have.)
slmgr.vbs /upk (This will uninstall your key)
slmgr.vbs /cpky (This will clear any registry key with your licence)
slmgr.vbs /ipk (Your Key) (This will install and activate your windows 10 product key)
Follow these guide lines below:
If you upgrade from a retail copy of any of these versions of windows. Windows 7, Windows 8 or 8.1, the Windows 10 license will still have retail rights carried over from your previous version. But it can only be a one time transfer.
If you upgrade from an Windows 7, Windows 8 or Windows 8.1 license and it was preinstalled on a new computer as a OEM license, it cannot be transferred to another pc.
If you brought a full retail copy of Windows 10, you have the right to transfer it as many times as you want, but only on one pc at a time.
