Check under &quot;Settings&quot;, &quot;Update &amp;&nbsp;Security&quot;, &quot;Recovery&quot;. There you should have your old installation to return to. This of course will only work if you haven't meanwhile run a disk cleanup which could have removed your old Windows.<br />
<br />
You can still upgrade to Windows 10 for free later if you want to. In fact it should then work directly from the DVD without needing to go through the upgrade again, as Windows 10 is already registered for that PC with the m$ servers. You will be asked for the key, just ignore that and skip those questions.

Thank you. What folder is Windows 10 in?
</div>


<div>
Your old install is in Windows.old which is a folder in Windows 10. Once you upgrade, Windows 10 is the operating system and not a folder.

Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.
