I've been using Windows 7 for 10 years, but with support ending (and the computer being 10 years old) I've dug into the pocket, and bought a new desktop, running Windows 10. I doubt, though, that the software I use for photo manipulation (an ancient thing called Arcsoft Photo Studio, that came with a Canon digital I bought in 2005) will work with Win 10. I need to replace this - very cheaply, or for free. Is GIMP any good? I also have to get my Canon film scanner working with Win 10.
