Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Office Home and Student 2007 cannot be used on Windows 11 because Office 2007 and earlier versions are not compatible with Windows 10 or later.
Since the original Office 2007 disc and product key are lost, they cannot be recovered from the new Windows 11 PC. The product key for Office 2007 is normally only available from the original packaging, Certificate of Authenticity, or the confirmation email from the original purchase. Without that key and media, Office 2007 cannot be reinstalled.
To use Office on the new Windows 11 computer, install a supported version of Office instead (for example, a current Microsoft 365 subscription or a newer perpetual Office version) that meets the system requirements for Windows 11.
