How can i run my Windows 10 on my HD
with new PC build ,MB,etc?
thankyou in advance.I really dont want to have to pay for a new copy.
 
Primary question - Where did this Win 10 come from?
If it was preinstalled from one of the major manufacturers, you're probably out of luck.

Upgraded from something else, or an OS that you purchased, you can transfer that license to new hardware

For the OS activation, read and do this before you change any parts:
https://support.microsoft.com/en-us/help/20530/windows-10-reactivating-after-hardware-change


For the actual operation and booting up, it will probably need a whole new install.
There are 3 basic outcomes with trying to move a drive with its OS to new hardware:
  1. It boots up just fine
  2. It fails completely
  3. It boots up, but you have issues later.
Prepare for a full install.
