Anyone know the difference between

SW_CD_NTRL_Windows_XPSP3_English_1_X14-60489.EXE (
SW_CD_Windows_XP_Professional_32BIT_English_32_XPs p3_MLF_X14-73974.EXE

One is Windows XP Professional Service Pack 3
The other is Windows XP Professional with Service Pack 3

Both are 500+MB.

I needed to redownload my media for that today and I did not have those
options before. Then again last time I downloaded that media SP1 hadn't
even come out...
