If you already have a COA then this is perfect, when it asks you for your number type it in (it may be stored in your BIOS too); It must be for Windows 7 Pro or Windows 10 Pro - any other code will not work and the Windows 7 codes may not work for much longer, that is up to Microsoft.If you need any other OS please do not hesitate to get in touch as we can supply up to date installation DVD's or Pen-drives.
