<p>I am using Aero Peek very often to navigate through open applications/explorer items in the taskbar. If you use it too, you have probably already noticed that thumbs open rather slow when you hover over the taskbar application.</p>
<p>Luckily there&#8217;s a way to speed this up so the thumbnail opens instantly as soon as you hover over any open application in the taskbar.</p>
<p>Here&#8217;s how to do it:</p>
<p>Hit Win ORB | Type REGEDIT | Navigate to: <b>HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced</b></p>
<p><b><img src="http://wincert.net/wp-content/uploads/2011/08/speed_up_thumb_preview_2.PNG" alt="" /></b></p>
<p>In the right pane right click on on the white area and create a <b>New DWORD (32-bit) Value </b>(if you&#8217;re using Windows 64-bit, if not mind the (32-bit). <!--more--></p>

<p>Type <b>ExtendedUIHoverTime</b> and click <b>OK</b> | Double click on the <b>ExtendedUIHoverTime</b> key and in the Value data box type <b>1 </b>| click <b>OK</b></p>
<p>Close the registry editor and restart your machine for changes to take effect.</p>
<p>Notice that thumbnails opens instantly as you hover over the application shortcut in the taskbar.</p>

<p>If you would like to revert changes we made now, just change the Value of the <strong>ExtendedUIHoverTime</strong> key in the registry to <b>0</b>. OR just delete the <strong>ExtendedUIHoverTime</strong> key.</p>
<p>On the other hand, if you would like to slow it up, you can use a custom value like 2000 or 3000 in the Value box.</p>
