Purchase product key

Settings to open the window after purchase.

Open "activation"
Click Change Product Key.
Enter the product key you purchased here, click Next, and then click Activate.
2. If you have no money to buy the product key.
You can use the activation tool on the network.
However, most of the activation tools on the network are activated in batches. How to activate them permanently?
I have two permanent activation tools here, one can activate all versions of Windows 10, but the link to this tool has expired and can't be found online.
There is also one that can only activate Windows 10 Professional Edition, Windows 10 Home Edition and Windows 10 Education Edition.
Download method:
Search for "Yunmeng Windows 10 Activation Tool"
Click download
Click "Activate" after opening, and wait for a moment to activate successfully.
The screenshot is very hard, hope to adopt it, thank you.
