It suits new PC builds, upgrades from an older edition and clean reinstalls alike - one key, permanently tied to your device once activated.
This license is made for one job: moving an existing machine up to Windows 11 Professional - whether you are on Windows 11 Home and need Pro features, or on an aging Windows 10 install and want a clean jump forward.
