I always set up keyboard shortcuts for programs I use constantly. Windows has natively supported this since at least XP; you just have to go into the shortcut properties and set a Ctrl+Alt+x shortcut.
I have Firefox, my documents folder, Photoshop, Illustrator, Steam, Skype, Minecraft, my 3D printer's control program, the recycle bin, and probably a couple others all on shortcuts. Super fast and easy to open.
