You can and it will normally work but two potential issues:

1) You may run into driver issues. It is a bit tricky getting round this if you run into such issues.

2) You will become deactivated as new mbo counts as new pc.

If you have a retail licence for W10, you can use on new pc.

If you do not, you need to use activation trouble shooter to transfer digital licence to activate new mobo.

Thank you it look to me difficult, I will take it to the shop. thank you

I rather doubt most shop know any better (than we do) about how to transfer licence or transfer OS without reinstalling. They are usually only any good at hardware, not software related issues.

It could end up costing you a lot of money, but with some patience we could guide you through the process.

Make sure they give you a clear up front cost before you spend any money.

Your computer specs says you have built a Z170 + i5. You must have used a Win 10 license on it.
As already mentioned, If the license used was a Retail type, you can use it on the new computer to activate it.
The shop will try to sell you a new license that you probably don't need.

Link Microsoft Account to Windows 10 Digital License

If you use MS account, even temporarily, you can link/unlink your licence to the "new" computer.
Even if it is OEM (thanks to EU laws), but in the worst case scenario, you can buy a new licence for $2.
