With the release of Windows Vista Service Pack 1 (SP1)&amp;nbsp;Principled has updated their results. Principled Technologies concluded the following when comparing business scenarios: 
&lt;UL&gt;
&lt;LI&gt;
&lt;DIV mce_keep="true"&gt;Overall, Windows Vista SP1 and Windows XP performed comparably on most test operations. Performance differences between the two operating systems were typically less than a half second. Significant differences of over a second occurred on only nine of 128 measures; Windows Vista SP1 led on eight of those.&lt;/DIV&gt;&lt;/LI&gt;
&lt;LI&gt;Windows Vista SP1 was noticeably more responsive after rebooting than Windows XP on several common business operations.&lt;/LI&gt;
&lt;LI&gt;Overall, Windows Vista SP1 was more responsive than Windows Vista on most comparisons. Performance differences between the two operating systems were typically less than a quarter second. &lt;/LI&gt;&lt;/UL&gt;
&lt;P&gt;Principled Technologies also concluded the following when comparing home scenarios:&lt;/P&gt;
&lt;UL&gt;
&lt;LI&gt;Overall, Windows Vista SP1 and Windows XP performed comparably on most test operations. Differences were typically less than a half second.&lt;/LI&gt;
&lt;LI&gt;Windows Vista SP1 was noticeably more responsive after rebooting than Windows XP on several common home operations.&lt;/LI&gt;
&lt;LI&gt;Overall, Windows Vista SP1 and Windows Vista performed comparably on most test operations, with differences typically less than a half second. &lt;/LI&gt;&lt;/UL&gt;
