Is my windows 10 key reusable?

[Jack_213]

Just contacted microsoft support, they say I'll be able to enter the activation key on the side of my PC when I change my CPU, Motherboard and RAM. How do I know it's reusable?

Link the key to a Microsoft Account and you will have no trouble with activation.

Read and do this before you change any parts:

If you bought a windows 10 license key (wich are quit expensive) you should be fine. If you bought an oem key from a website like kinguin you can't use it on a new pc.
