<p>So, Windows 10 Upgrade is being rolled out worldwide, and I have ‘reserved’ my upgrade.</p>
<p>Currently my computer is running Windows 7 Pro 32-bit. I’m planning to ‘upgrade’ it to Windows 10 64-bit (via fresh install, of course).</p>
<p>After reading many references, these will be the steps I’ll do:</p>
<ul>
<li>
<p>Let the “Get Windows 10” app upgrade my OS to Windows 10 32-bit</p>
</li>
<li>
<p>Note the activation key</p>
</li>
<li>
<p>Download the Installation Media for Windows 10, but choosing 64-bit instead</p>
</li>
<li>
<p>Perform a clean install</p>
</li>
<li>
<p>Reactivate using the activation key in Step <span class="hashtag-raw">#2</span></p>
</li>
</ul>
<p>(Of course I’ll backup my data first.)</p>
<p>However, I still have some questions:</p>
<ul>
<li>
<p>On Windows 7, the activation key does not differ between 32- or 64-bit versions. Is it still so with Windows 10?</p>
</li>
<li>
<p>Will I be able to download a different architecture on Step <span class="hashtag-raw">#3</span>?</p>
</li>
<li>
<p>Is there anything I need to prepare beforehand?</p>
</li>
</ul>
<p>Thank you for your assistance.</p>
