OS question concerning re-use in custom PC

So I've recently ordered a new custom pc and the parts are on their way. I was hoping that my current OS (Windows 10) on my current PC could transfer to this new one. I have the OS file downloaded onto a USB. If I booted my custom PC up with this USB would I run into any problems? Are OS's tied to only one PC?

It depends

Try using it. If it doesn't work, call Microsoft or buy a new license. That's basically all you can do.

It's far more complicated than that.

Windows since about 3.0 isn't so much tied to the PC but the hardware. So when I install Windows today there are drivers and more that optimize to the hardware. Change the motherboard and Windows usually fails to boot. However an old OS like DOS didn't care.

Some Linux versions don't care so much either as I can boot my TAILS OS from USB on a dozen PCs without trouble.

Won't work

Can't boot installed windows from a USB port.

Here's the deal.

The windows OS is tied to a computer's motherboard. If it is an OEM version then that is where the OS will stay...with the motherboard. But if this was a "retail" OS, then it can move to another computer. You might need to explain that to MS. I would think that win10 is tied to your upgraded windows. If that was retail then I say it only fair that this win10 is also "retail". Oh, you should be able to install win10 from your previous usb. Give it a shot and let us know how it goes. Good luck.

Couple thing to look out for.

During the install process it will ask you for the "KEY", First encounter, use "SKIP" and the 2nd encounter, use "do it later". Not sure this will be the same for you or not.
