The first way: first, we return to the traditional desktop location of the WIN8 system, and then press the Win+x shortcut on the WIN8 computer keyboard to open the shortcut menu of the computer, in the Open shortcut menu, we click into the system options.
In the System window that opens, let's review the Windows activation information that you've delegated, and then click "View in Windows Activation Information" at the bottom of the window.
In the new window we will be able to view the details of the activation of the WIN8 system on our own computer, there is an activation time under the key, if not, it means that your system is pirated.
The second method: If you think the above method is more troublesome, you can also use the following method. We return to the traditional desktop location of the WIN8 system, and then press the Win+r shortcut key on the keyboard to open the computer's running window, in the Open Run window we enter the command "SLMGR.VBS/DLV" and click Enter, so that the activation information will appear, if the pop-up box flashed over, also represents piracy.
