SwissSys has modest system requirements. Pretty much any computer running a full version of Windows from Windows 7 on up will do.
Note, however, that this rules out most Chromebooks which typically come with a reduced operating system.
Memory requirements are likewise minimal, as is storage space.
SwissSys will also run on the Mac, provided it has Windows emulation software installed, such as Parallels, or Apple's own BootCamp, which is free.
