In this guide, I&#8217;ll outline the steps to complete this task.<\/p>\n<p>It is important to clarify that <a href=\"https:\/\/pureinfotech.com\/windows-11-26h1-release-date\/\">Windows 11 26H1<\/a> is not a feature update for current devices. Microsoft has shared details saying that version 26H1 is not an upgrade path for <a href=\"https:\/\/pureinfotech.com\/windows-11-new-features-2025\">Windows 11 25H2<\/a> or earlier releases.\u00a0<\/p>\n<p>The update will only be availble on new ARM64 PCs, starting with devices powered by the Snapdragon X2 Plus, Elite, and Extreme processors. If you own a computer running on Intel or AMD hardware, <strong>Windows 11 26H1 will never be offered to your system<\/strong>.<\/p>\n<p>However, if you must download and install version 26H1, you can use UUP Dump, which is a tool that lets you create a custom <a href=\"https:\/\/pureinfotech.com\/tag\/windows-11\">Windows 11<\/a> ISO from any public preview. It is a script that downloads the latest builds from Microsoft servers and creates an unofficial ISO file you can use to install the operating system.<\/p>\n<p>Although the company makes the <span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\">Windows 11 ISO available for previews, allowing users to test the\u00a0clean installation\u00a0and\u00a0in-place upgrade processes on virtual machines and spare computers, this isn&#8217;t<\/span>\u00a0always the case.<\/p>\n<p>In this <a href=\"https:\/\/pureinfotech.com\/tag\/how-to\">guide<\/a>, I will walk you through using the UUP Dump tool to download the ISO file for any publicly available Windows 11 preview.<\/p>\n<div id=\"tip-box\"><span><strong>Important:<\/strong> This version of the operating system isn&#8217;t finished, and you won&#8217;t find any new features since this is only a platform upgrade to support upcoming processors.
