вот что имею по версии - апгрейд с Вин7, ритейл версия.

то есть я могу просто выключить комп, поменять внутренности, и по включению оно переактивацию проведет?
или нужно, как пишут, сначала
Uninstall the product key – this is the closest to deactivating the Windows License. This method does not inform Microsoft Activation Servers; the license is no longer in use on the machine; it will avoid conflicts down the road if Microsoft Activation Servers were to detect the license in use on more than one system.
а потом после смены запчастей
How to Reactivate the License
Once you arrive at the desktop, you will need to re-enter your product key. Press Windows key + X then click Command Prompt (Admin).
At the command prompt, enter the following command: slmgr.vbs /ipk xxxxx- xxxxx- xxxxx- xxxxx- xxxxx. Hit Enter on your keyboard; you will receive a confirmation the product key was updated. Close the command prompt and then proceed to reactivate by telephone or Contact Support.
