Transfering license from desktop to laptop, and throwing desktop away

[GeorgeilotS]

Hello,
I have a custom built desktop at an office, it was running Windows Xp pro with the license glued on the side. At a later time a full license was purchased for windows 7 pro oem, and glued on the side of the computer. The system was wiped and Windows 7 pro freshly installed (not upgraded).
Now a new system with Windows 10 pro was bought to take it's place.
My question is there, the office has a Windows XP Pro laptop, that must be upgraded to Windows 7 pro. Am I able to use that license from that old desktop for Windows 7 Pro on this winxp laptop to install Windows 7 pro? If so, how would I go about doing it? Just an upgrade and use that product key?

The laptop license will be an OEM copy of the OS, this is managed by the OEM of the laptop and would not be transferable to the new system. the additional win7 laptop is also an OEM license but in this case the support would be the responsibility of your Company IT department.

You need to purchase a new license for the laptop, but, if you can get one an upgrade license would be OK as the XP pro to Windows 7 is a valid upgrade
