I have one license and two computers, can I use the same license to activate Windows 10 on both devices?
Best answer: No.
You can only activate one copy of Windows 10 with one license.
Furthermore, if you have OEM (branded) device, such as from HP or Dell, these devices use an OEM license that is only tight to one machine, and you can’t transfer it to another device. However, if you buy a retail version of Windows 10, you can uninstall the OS on one computer, and transfer the license to another computer.
Keep in mind that we’re just covering consumer licensing, as there are options, such as using volume licenses that you can use to activate multiple copies of Windows 10, but this usually applies for business with Microsoft contracts.
