Do you folks mean programs *on* the desktop, or just not Metro programs or applets or gadgets, or whatever they are?
By "desktop app" I mean traditional windowed applications that have been around for 20+ years, as opposed to crappy metro apps.
This applies to various file types, but I'll use jpg as an example.
Starting with Win8, double clicking a jpg takes you to a tablet-land Photos program. This is because Microsoft now thinks everyone is using a 4-10" phone or tablet. Your entire screen is now dedicated to looking at that one picture. There's no taskbar or X to close. You have to hit Win+D to get back to the desktop but since most people don't know any shortcut keys, they'll struggle to find their way back to where they were.
I carry mp3, gif, jpg, png, tif, avi, m2t, m4v, and wmv files on my flash drive so when I set up a new Win8 PC for someone, I can manually associate these file types with either the Windows Photo Viewer (thankfully they didn't actually remove it from Win8) or Windows Media Player. Installing Acrobat Reader or any other PDF viewer will take the association for PDF files away from Win8's useless "reader" app.
