I have Office and several Adobe programs and financial management installed, plus the usual gaggle of utilities. I am not a gamer. My C partition on an SSD is 180 GB, with about 60 GB free.I recently raised my minimum disk size for Window 10 to 100GB. But that's really tight. After Office. Windows 10 needs at least 20G of free disk space now for updates.
This is a far cry from what was required for Windows 10 when it was released.
