A:Answer It works with Windows 10 but Nikon users might have a few issues if working in Raw.
So Windows 10 will not read or let you preview NEF files, you do however have a few options......
*Right click image, hit open with, search and open file with LR, or PS. No preview on Windows but everything can be seen via LR or PS. *Another option which will allow you to preview files on Windows is using a NEF to DNG converter which you can download from Adobe's website for free.
I have tried both ways and prefer opening file using LR or PS. The NEF to DNG converter is more convenient but drastically reduces the resolution of the pictures.
