<span dir="auto" style="vertical-align: inherit;"><span dir="auto" style="vertical-align: inherit;">To activate Windows legally, you can use a digital license that's linked to your Microsoft account, enter a 25-character product key you bought from Microsoft or an authorized reseller, or&mdash;if you're in an organization&mdash;use volume licensing managed by your IT team. Open Settings &rarr; Activation (or Update & Security &rarr; Activation on older Windows), then either sign in with the Microsoft account that holds your digital license or click Change product key and enter the key. If activation fails after a hardware change, use the Activation troubleshooter and the &ldquo;I changed hardware on this device&rdquo; option to reactivate via your Microsoft account.</span></span>

<span dir="auto" style="vertical-align: inherit;"><span dir="auto" style="vertical-align: inherit;">Microsoft Office activates either by signing in with the Microsoft account tied to a Microsoft 365 subscription or by entering a product key for one-time purchases (Office 2019/2021). Open any Office app, go to File &rarr; Account (or Office Account), and sign in to automatically activate if your subscription is linked. For product-key installs you can use office.com/setup or the change product key option inside older Office versions. Business editions use volume licensing (KMS/MAK) handled by IT.</span></span>

<span dir="auto" style="vertical-align: inherit;"><span dir="auto" style="vertical-align: inherit;">If activation repeatedly fails, sign out and sign back in, run the built-in troubleshooters, or contact Microsoft Support for help. Avoid unofficial activators or &ldquo;cracks&rdquo;: they violate Microsoft's license, often carry malware, and can break updates or support. If cost is a concern, use Office for the web (free at office.com) or free alternatives like LibreOffice.</span></span>
