You&#8217;ll see &#8220;Windows is activated&#8221; with your activation method, or an error message if activation failed. You can also open Command Prompt and run <code>slmgr \/xpr<\/code> to check your license status.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I use Windows without activating it?<\/h3>\n\n\n\n<p>Yes, Windows will continue to work without activation, but with limitations. You&#8217;ll see a persistent &#8220;Activate Windows&#8221; watermark on your desktop, you won&#8217;t be able to personalize your desktop (wallpaper, colors, lock screen), and some features may be restricted. There are no time limits \u2014 unactivated Windows doesn&#8217;t expire.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What&#8217;s the difference between a digital license and a product key?<\/h3>\n\n\n\n<p>A <strong>product key<\/strong> is a 25-character code (XXXXX-XXXXX-XXXXX-XXXXX-XXXXX) that you enter manually to activate Windows. A <strong>digital license<\/strong> (also called digital entitlement) is linked to your Microsoft account and hardware \u2014 it activates Windows automatically without entering a key. If you upgraded from Windows 7\/8 for free or bought Windows from the Microsoft Store, you likely have a digital license.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Will I lose my files if Windows is not activated?<\/h3>\n\n\n\n<p>No. An unactivated Windows installation does not delete, lock, or restrict access to your files. All your documents, photos, and applications remain fully accessible. The only restrictions are cosmetic (watermark) and personalization-related. Your data is completely safe.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do I transfer my Windows license to a new computer?<\/h3>\n\n\n\n<p>Only <strong>Retail<\/strong> licenses can be transferred to a new PC. First, deactivate the old PC by running <code>slmgr \/upk<\/code> in an elevated Command Prompt. Then enter the same product key on your new PC. <strong>OEM<\/strong> licenses are tied to the original motherboard and cannot be transferred. <strong>Digital licenses<\/strong> linked to a Microsoft account can sometimes be reactivated via the Activation Troubleshooter after hardware changes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"get-a-product-key\">Need a Genuine Windows Product Key?<\/h2>\n\n\n\n<p>If your current product key is invalid, expired, or you simply need a new one, we offer <strong>genuine Windows product keys at affordable prices<\/strong> with email delivery and activation help under the published policy.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n\n<div class=\"wp-block-button is-style-fill\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/winprokeys.com\/shop\/\">Browse Windows Product Keys \u2192<\/a><\/div>\n\n<\/div>\n\n\n\n<p>Looking for more Windows help?
