It allows you to roll back to a previous version of Windows if something goes wrong.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because it contains a complete copy of your old operating system, it can take up tens of gigabytes of storage space. However, Windows treats this as a protected system folder, so you cannot simply select it and press Delete.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The safest and most reliable ways to remove it are built right into Windows.<\/p>\n\n\n\n<h2 id=\"method-1-use-storage-sense-the-easiest-way\" class=\"wp-block-heading\">Method 1: Use Storage Sense (The Easiest Way)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Windows has an automated tool designed specifically to hunt down and destroy large, temporary system files.<\/p>\n\n\n\n<ol class=\"wp-block-list has-palette-color-8-background-color has-background\">\n<li>Open the Start Menu and click the Settings gear icon (or press <code>Win + I<\/code>).<\/li>\n\n\n\n<li>Go to System and then select Storage.<\/li>\n\n\n\n<li>Click on Temporary files (wait a few moments for Windows to scan your drive).<\/li>\n\n\n\n<li>Look for the checkbox labeled Previous Windows installation(s).<\/li>\n\n\n\n<li>Check that box, scroll back to the top of the window, and click Remove files.<\/li>\n<\/ol>\n\n\n\n<h2 id=\"method-2-use-the-classic-disk-cleanup-tool\" class=\"wp-block-heading\">Method 2: Use the Classic Disk Cleanup Tool<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you prefer the traditional Windows interface, the legacy Disk Cleanup utility will get the job done cleanly.<\/p>\n\n\n\n<ol class=\"wp-block-list has-palette-color-8-background-color has-background\">\n<li>Press the <code>Win<\/code> key, type Disk Cleanup, and press <code>Enter<\/code>.<\/li>\n\n\n\n<li>Select your main system drive (usually C:) and click OK.<\/li>\n\n\n\n<li>Once the window loads, click the button near the bottom left labeled Clean up system files (you may need to grant administrator permission and select the C: drive again).<\/li>\n\n\n\n<li>Scroll through the list of checkboxes and find Previous Windows installation(s).<\/li>\n\n\n\n<li>Check the box next to it, make sure you haven&#8217;t accidentally checked anything else you want to keep, and click OK to permanently delete the folder.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"method-3-use-command-prompt-the-forceful-way\" class=\"wp-block-heading\">Method 3: Use Command Prompt (The Forceful Way)<\/h2>\n\n\n\n<p class=\"has-palette-color-8-background-color has-background wp-block-paragraph\">If the settings menus are hanging or refusing to delete the folder, you can force Windows to drop the directory permissions using an elevated Command Prompt.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Press the <code>Win<\/code> key, type <strong>cmd<\/strong>, right-click <strong>Command Prompt<\/strong>, and select <strong>Run as administrator<\/strong>.<\/li>\n\n\n\n<li>Type or paste the following command to take ownership of the folder and press <code>Enter<\/code>:<\/li>\n<\/ol>\n\n\n\n<pre class=\"wp-block-code\"><code>takeown \/F C:\\Windows.old \/A \/R \/D Y<\/code><\/pre>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li>Next, paste this command to grant full control permissions and press <code>Enter<\/code>:<br>&#8220;`cmd<br>icacls C:\\Windows.old \/grant Administrators:F \/T \/C \/Q<\/li>\n\n\n\n<li>Finally, run the removal command to delete the folder entirely: rd \/S \/Q C:\\Windows.old<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">\u26a0\ufe0f <strong>Important Note Before Deleting<\/strong><br>Once the Windows.old folder is deleted, you lose the ability to easily &#8220;Go Back&#8221; to your previous version of Windows via the recovery settings menu. Only delete this folder if you are entirely satisfied with how your current system upgrade is running and you are certain you do not need any old files trapped inside it.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"cls has-palette-color-2-color has-palette-color-1-background-color has-text-color has-background has-link-color wp-elements-bb59f6d0306f9f4048a805770264521b wp-block-paragraph\">Think of the Windows.old folder as an insurance policy that has already expired. If you upgraded your machine more than ten days ago and everything is running smoothly, keeping it around is just wasting massive chunks of storage space. Using the native Windows tools like Storage Sense or Disk Cleanup is always the best way to handle this, as it allows the operating system to safely unhook the system files without breaking any hidden directory permissions.<\/p>\n\n\n<style><\/style><style><\/style>\n<h6 class=\"wp-block-heading\">More Information \u2139<\/h6>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/gtechbooster.com\/i\/windows\/\" data-type=\"post_tag\" data-id=\"888\">Windows OS<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Learn the safest and most effective methods to remove the large Windows.old folder from your hard drive, freeing up valuable storage space after a major system upgrade.<\/p>\n","protected":false},"author":4,"featured_media":79308,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_gspb_post_css":"","footnotes":""},"categories":[2],"tags":[263,889,1594,891,892,895,888,898],"class_list":["post-1743","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-how-to","tag-disk","tag-windows-10","tag-windows-11","tag-windows-7","tag-windows-8","tag-windows-nt","tag-windows","tag-windows-xp"],"blocksy_meta":{"styles_descriptor":{"styles":{"desktop":"","tablet":"","mobile":""},"google_fonts":[],"version":6}},"_links":{"self":[{"href":"https:\/\/gtechbooster.com\/api-json\/wp\/v2\/posts\/1743","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gtechbooster.com\/api-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gtechbooster.com\/api-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gtechbooster.com\/api-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/gtechbooster.com\/api-json\/wp\/v2\/comments?post=1743"}],"version-history":[{"count":1,"href":"https:\/\/gtechbooster.com\/api-json\/wp\/v2\/posts\/1743\/revisions"}],"predecessor-version":[{"id":79309,"href":"https:\/\/gtechbooster.com\/api-json\/wp\/v2\/posts\/1743\/revisions\/79309"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/gtechbooster.com\/api-json\/wp\/v2\/media\/79308"}],"wp:attachment":[{"href":"https:\/\/gtechbooster.com\/api-json\/wp\/v2\/media?parent=1743"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gtechbooster.com\/api-json\/wp\/v2\/categories?post=1743"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gtechbooster.com\/api-json\/wp\/v2\/tags?post=1743"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
