Changing your CPU may make Windows flag your install as non-genuine. In theory changing only one part is OK because it will sample the serial numbers for all the rest of the hardware and decide that you are still genuine, but not 100 percent on the processor change. If you change CPU and graphics card then you are fairly sure to be re-activating Windows, or calling Microsoft to explain what is happening, and then they will probably give you a code to re-activate.
The only way around this might be if you have an OEM system that has the product key embedded into the BIOS/EFI firmware of the board. This has worked for me in the past with Win8, never had a need to try with Win 10 yet. But if you built it yourself from parts, you may be out of luck.
