I have a couple camera apps from the mid 'aughts that were written for Windows XP that still function fine under Windows 10. Same thing with an old photo scanner, that just only recently failed. My last SCSI dependent peripheral. Ran fine on Windows 10, on ancient software, using ancient TWAIN SCSI drivers, until the scanner itself failed. As I moved from XP -> 7 -> 8.1 -> 10, the first thing I did was load up all my old photo software to be sure it would work.
