No need to go the shop.

Use a 8GB thumb drive to download the windows 10 from the Microsoft website into thumb drive.
After installing,remember to set your bios/UEFI boot as thumb drive when installing new windows 10.

By right. windows will auto activate the windows 10 license after installing. As window license follows your hardware.

To play safe, check and copy your windows 10 product key by running this command in Command prompt mode first.
