Bill383 :
I already know that i cannot transfer my dell oem key to another computer since it is tied to the motherboard. That key is for the home verstion of windows 10, therefore it it did not activate, after that i bought an OEM key online for cheap hoping to resolve the issue. If i put that key on windows right now will i be able to remove it and use it with another pc in the future or is it one time use? Or is it one PC use(meaning can i only use it on this dell once i first activate).
Bill, agreed it is confusing but here are the relevant terms from the Windows 10 OEM license:
Transfer. The provisions of this section do not apply if you acquired the software as a consumer in Germany or in any of the countries listed on this site (aka.ms/transfer), in which case any transfer of the software to a third party, and the right to use it, must comply with applicable law.
a. Software preinstalled on device. If you acquired the software preinstalled on a device (and also if you upgraded from software preinstalled on a device), you may transfer the license to use the software directly to another user, only with the licensed device. The transfer must include the software and, if provided with the device, an authentic Windows label including the product key. Before any permitted transfer, the other party must agree that this agreement applies to the transfer and use of the software.
b. Stand-alone software. If you acquired the software as stand-alone software (and also if you upgraded from software you acquired as stand-alone software), you may transfer the software to another device that belongs to you. You may also transfer the software to a device owned by someone else if (i) you are the first licensed user of the software and (ii) the new user agrees to the terms of this agreement. You may use the backup copy we allow you to make or the media that the software came on to transfer the software. Every time you transfer the software to a new device, you must remove the software from the prior device. You may not transfer the software to share licenses between devices.

HERE for full OEM license terms.
In summary, it says that the OEM version that came installed on a device stays only with the original device.
