What are these programs?

hey guys

i was wondering if anyone could tell me what these programs are on my computer. i was going through my computer and removing old programs that i never use anymore and on the Add or Remove Programs list these 6 programs show up:

MSXML 4.0 SP2 (KB925672)
MSXML 4.0 SP2 (KB927978)
MSXML 4.0 SP2 (KB936181)
MSXML 4.0 SP2 (KB954430)
MSXML 6.0 Parser (KB925673)
MSXML 4 Parser

i was wondering if anyone knew what they are, and if i need to keep all of them.

thanks for any help
