Windows blocked the download

A blue "Windows protected your PC" box appeared instead of w0a. Here is what it means and how to check the file is really ours before you continue.

Where the key goes, what happens when you press activate, and what each error means.

 I changed my PC or my parts

Your key says it is already in use somewhere else. How to release it yourself from the old machine, and when to write to us instead.

 What w0a collects about you

The complete list of what leaves your computer, and what stays on it. Short, because the list is short.
