Using XP Media and MS word 2003

When I open My Documents, normally each file has to the left of the file name a sheet of paper with a Blue W.

I was trying to clean out some junk software which came with my Dell computer. Removed: Sonic Encoders, Viewpoint Media Player, WebcyberCoach, Wild Tangent Wed Driver, and Word Perfect.

Now when I open My Documents, to the left of each file name, I do not have the sheet with the Blue W, I have a note pad, with red A.

Opened several of the files and they look the same, but this change in designation from W, which presumably stands for Word, to A, bothers me.

Did I do something wrong to cause this change? How do I get my Blue W back?
