Replacing MB. Do I need to buy a new copy of Windows 10

[phughes200]

I think I need to replace my MB on my Lenovo ThinkPad Yoga 260. The system will not power on. No beeps. Nothing happens when I push the power on button.

Questions:

1) If I buy a used motherboard, will I need a new copy of Windows 10? Isn't the windows key stored on the motherboard so I would that key still work?

2) Can I upgrade to an I7? The currents system has a I5-6200U. Is it worth it? It appears that both use the same heat sink.

3) There is an listing on EBay for the same sytem I have (same type, different version) without a hard drive. Can I just install my drive in the new system without buying and installing a new copy of windows?

Help!

You should try it first, especially if you have a M$ account. M$ has changed their policy with W10. It should allow for a couple moves now. But that may depend on if it was registered/activated with a M$ account or not. And I'm not sure if that applies to OEM installations, although I suspect it does.

For an actual broken and replaced board, MS is generally very lenient on reusing the license.
