===Service Pack 1===
Service Pack 1 (SP1) for Windows XP was released on September 9, 2002. It contained over 300 minor, post-RTM bug fixes, along with all security patches released since the original release of XP. SP1 also added USB 2.0 support, the [[Microsoft Java Virtual Machine]], [[.NET Framework]] support, and support for technologies used by the then-upcoming ''Media Center'' and ''Tablet PC'' editions of XP.<ref name=pcmag-xpsp1>{{cite web|title=Windows XP SP1 Irons out the Wrinkles|url=https://www.pcmag.com/article2/0,2817,526004,00.asp|work=PC Magazine|access-date=January 26, 2014|url-status=live|archive-url=https://web.archive.org/web/20140226221844/http://www.pcmag.com/article2/0,2817,526004,00.asp|archive-date=February 26, 2014}}</ref> The most significant change on SP1 was the addition of ''Set Program Access and Defaults'', a settings page which allows programs to be set as default for certain types of activities (such as media players or web browsers) and for access to bundled, Microsoft programs (such as Internet Explorer or Windows Media Player) to be disabled. This feature was added to comply with the settlement of ''[[United States v. Microsoft Corp.]]'', which required Microsoft to offer the ability for OEMs to bundle third-party competitors to software it bundles with Windows (such as [[Internet Explorer]] and [[Windows Media Player]]), and give them the same level of prominence as those normally bundled with the OS.<ref name="cnet-xpsp1">{{cite web | url=https://reviews.cnet.com/windows/microsoft-windows-xp-service/4505-3672_7-20039834.html | title=Microsoft Windows XP Service Pack 1 review | publisher=CNET Networks | work=CNET | access-date=January 26, 2014 | url-status=live | archive-url=https://web.archive.org/web/20080209135918/http://reviews.cnet.com/windows/microsoft-windows-xp-service/4505-3672_7-20039834.html | archive-date=February 9, 2008 | df=mdy-all|date=<!--N/A-->|first1=Edward|last1=Mendelson |author-link1=Edward Mendelson}}</ref>
