I’m still running Win98 on a couple of my computers. And XP on the rest, except for one Vista and one Win 7. I can’t tell the difference most of the time. It bothers me far more when they change the Office Suite.
I find Office 2010 difficult to navigate. They’ve moved and hidden all my favorite tabs. I like the 2003 version much better.
Install this:

Then hit Menu on that crappy Ribbon Menu, and Office 2003 all comes back like it was. On all Office Suite Products. Sweet.
