Windows 7: Bloat

I used to use Virtual XP on my Windows 7 OS. Found out I didn't need it so uninstalled it.
However, there are some files that I don't know if I should keep or not. Maybe you guys can help me.
They are:



Group One
MSXML 4.0 SP2 KB 973688
MSXML 4.0 SP2 Parser and SDK
MSXML 4.0 SP3 Parser
MSXML 4.0 SP3 Parser and KB 973685

Group Two
MS Visual C++ 2005 Redistributal
MS Visual C++ 2008 ATL Update KB973924-X86 9.0.307294148
MS Visual C++ 2008 Redistributal -86 9.0.30729017

Group Three
MS Network Monitor 3.4
MS Network Monitor or Parser 3.4

Thanks
