Sometimes you might want to open a file with a specific program, but you don’t necessarily want it to open with that program every time. So what do you do?
Follow me, Windows 7′ers!
Just Right-Click on the program you’d like to use for limited file viewing (Notepad, in my case) and choose “Pin to Taskbar”.
This will put what is essentially a quick launch-like icon on your task bar. Now, locate a file you’d like to open, hold Shift, and drag it to the icon you pinned to your taskbar.
This trick also works in Windows Vista, although you won’t need to pin anything to the taskbar. Just make sure the program you want to use to open stuff is in your quicklaunch and follow the same steps.
