How to activate genuine system after win8 reloading

We know that Win8 has adopted the upgrade installation method in China this time. It is no longer installed through CD or other media, but needs to use the “Win8 Upgrade Assistant”. With the Win8 Upgrade Assistant, users can go straight to the process of purchasing genuine serial numbers and installing the system.
Buy Product Keys

So there is usually no problem with activation during Win8 installation, but reinstalling the system is a bit different.

There are some things that are very important here, we have to come up and say it separately. That is when we first use "Win8 upgrade assistant", when installing Win8, the system will download a Win8 installer to our computer, this file must be saved, reload it depends on it.
This program is very important

If you have lost this program, don't worry, you can download it again in the original return receipt email of Win8. You can make it into a CD or a USB stick and then you can use it as a Win8 installation disk.
Download the installer again

When we need to reinstall the system, you can open this program directly by using CD or USB flash drive. This program has skipped the initial purchase interface, the first step we have to do is to enter the product key, and then the normal installation steps.
