First of all, it won’t look exactly the same. But you can make it look a lot more like QuickBooks 2012 (or prior) than it does by default, which looks like this:
Some (many?) folks don’t like the monochromatic look that was one of the most obvious changes in the 2013 version.
To make it look more like it used to, first of all make sure that you have R6 update (or later) installed. Prior to R6, you were pretty much stuck with the black/white/gray mode. To check for updates, just click Help / Update QuickBooks… and let it check for more current updates than you currently have installed.
So after getting R6 or later installed, click Edit / Preferences. Click Desktop View in the left pane. You’ll see this:
Click the checkbox for “Switch to colored icons/light background on the Top Icon Bar” and then click OK.
Now click View, and click “Top Icon Bar”.
Voila! This is what your QuickBooks desktop will then look like:
It’s a beauty, ain’t it? Nice, colorful icons up top, just like you’re used to. They changed the graphics for the icons, and I think the font is a little different, but it’s a lot more like the look you had in 2012 and prior versions.
