Is there any way to make the shop that you bought the laptop from buy you a real license for the computer?  If they said it comes with Windows, as a reseller, they should be legally required to provide an official certificate of authenticity.
 
Or maybe get a refund?
 
Else, you will probably have to bite the bullet and pay for a new Windows license.  If you upgrade your Music Laptop, that upgrade will be tied to that device.  You cannot activate the same Windows license on two different devices.  You might be able to move it, but I assume your goal is to have two working laptops ...

I run a RME BabyfacePro on a gaming laptop with Windows 10 Home with no problems, but I haven't tried the Creators update yet. Apparently you can trick Windows 10 Home not to download big updates automatically by setting your wifi connections to "metered", so for the time being my computer has not automatically done the latest update. Before the BabyFace Pro, my old MOTU 828x would make Windows 10 give me the Blue Screen of death on occasion with a message related to the MOTU driver.

That "metered" setting is a great hack!  I'll just add that you will need to set it on each wireless network that you connect to.  Otherwise, if you are traveling with a laptop and connect to a new wireless network, you could receive unwanted updates.  The setting should be remembered for any connections that you save and visit again.

Vietnamese shop, it's just not worth the stress. I'm going to go in next week, but they are pretty useless.
 
So I'm guessing I need to buy a windows10 but if I'm going to, I'd prefer to use it for my Good laptop. So if I could transfer the Good laptops Windows license to the dodgy laptop, and then put a clean instill of a my new Windows onto this Good Laptop, then I think I make the best out of a bad situation.
 
I don't know if you can move licenses this way.I've never bought an opertating system before. Things like OEM confuse the hell out of me

Officially you can't move a Windows OEM license, since it is supposed to be tied to the hardware it was sold with.  But the rules have been a gray area for resellers, as MS seems to "allow" OEM licenses to be sold without hardware attached online.
 
Back in the Win XP and Win 7 days a lot of home builders would use the same OEM license each time they upgraded to new hardware, and it usually worked with a telephone activation.
 
I haven't tried it since Windows 10, but MS has changed their activation system a bit.  Must be due to all that piracy in Asia ...
 
Windows 10 is now activated with a "digital entitlement".
 
In Windows 10 (Version 1607 or later), you can link your Microsoft account to the Windows 10 digital license on your device. This can help you reactivate Windows using the Activation troubleshooter if you make a significant hardware change later, such as replacing the motherboard.

I run a local account only, but I would consider doing this temporarily if I was planning a hardware upgrade.  I would switch back to local only after the upgrade if the link was persistent.

Windows 10 Home with metered wifi here. You have to be diligent about manual updates though. If you use Defender it'll need updating regularly to keep current.

Home also won't recognize multiple processors. I'm running a Dell Precision T5400 with 2 x Xeon processors and had to move to Pro to be able to use both.
