You don’t need to find another one actually. You can still use it just fine without activating it, that is if you don’t mind a little watermark on the bottom right corner of the screen. I personally haven’t noticed any significant differences between an activated and non-activated copy of Windows (just some minor limitations which you most likely won’t even notice). Should be good enough if you’re just testing it out.

Edit:

You also don’t need a full on internal disk to do this either. You can use a program called “WinToUSB” which will let you install windows directly on a USB thumb drive (with enough storage capacity of course).

OK thanks @ikk157.  I was unsure about that as I thought Microsoft wouldn't allow you past the installation point where it asks you for a Product Key - when you don't have one.  Possibly then there must be an option at this point where one can delay the activation?
