<p>Usually vous pouvez activate the same copy of windows about 3 times avant vous allez be forced to call the activation line to do the processus. Cependant, if vous êtes reinstalling on identical (or nearly identical; changing the disque dur devrait être fine) matériel, there’s no point in wasting a reactivation, so c’est good to be able to back it up directly. Il y a two ways you could do this.</p>

<p>Si vous <em>want</em> to do a full reinstall, it is possible to back up your activation fichiers beforehand, and ensuite restore them once the reinstall is done. I did this récemment using <a href="http://www.mydigitallife.info/2009/09/24/how-to-backup-and-restore-windows-7-and-server-2008-r2-activation-status-activate-offline-on-reinstall/">these instructions</a>, and it was super easy. To summarize (avec some of my own rewording and clarification):</p>
<blockquote></blockquote>
<ul>
<li></li>
</ul>
<p>Back up</p>
<p><code>%WINDIR%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareProtectionPlatform\tokens.dat</code></p>
<ul>
<li></li>
</ul>
<p>Back up</p>
<p><code>%WINDIR%\System32\spp\tokens\pkeyconfig\pkeyconfig.xrm-ms</code></p>
<ul>
<li></li>
</ul>
<p>If using Windows 7 x64, also back up</p>
<p><code>%WINDIR%\SysWOW64\spp\tokens\pkeyconfig\pkeyconfig.xrm-ms</code></p>
<p>Vous allez need administrative<br>
privileges to copy these fichiers, and<br>
may need to take ownership du<br>
fichiers. Si vous need help avec that,<br>
comment below and I’ll add details<br>
about comment do that.</p>
<ul>
<li>Write down your clé de produit. Depuis you have a retail installation, you<br>
should déjà have it sur le disk’s<br>
packaging. Vous pouvez également use logiciel<br>
like <a href="http://www.gtopala.com/">SIW</a> to extract it.</li>
</ul>
<p>Once you have backed all of those up,<br>
go ahead and reinstall. When prompted<br>
to enter your clé de produit during<br>
installer, leave it blank, and choose to<br>
activate later. Once the installer is<br>
done:</p>
<ul>
<li>
<p>Arrêtez le logiciel protection service by running <code>net stop sppsvc</code><br>
in an elevated invite de commandes</p>
</li>
<li>
<p>Restore each du fichiers you backed up avant vers leir original<br>
locations</p>
</li>
<li>
<p>Redémarrez le logiciel protection service by running <code>net start sppsvc</code><br>
from an elevated invite de commandes</p>
</li>
<li>
<p>Run <code>slmgr.vbs -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx</code> from an<br>
elevated invite de commandes, using your<br>
clé in place du Xs</p>
</li>
</ul>
<p>Finally, redémarrer. Your système should be<br>
activated; vous pouvez check this by going<br>
to Système Properties from My Ordinateur.</p>

<p>The method which I would en fait advise is to do a full image backup. Si vous have an external disque dur, ensuite vous pouvez go vers le Backup and Restore panneau de configuration and choose to “Créez un système image”. Cela va make a copy of tout sur votre système, which vous pouvez ensuite restore onvers le nouveau disque dur using the recovery tools depuis le installer disk. J’ai fait this avant également, and it fonctionne great - when I had an hdd die, I put in a nouveau one and had tout back to exactly how it was avant right away when I restored the système image.</p>
