how to remove msxml4 without breaking stuff

Kaspersky scan says my two msxml4.dll files are vulnerable, one in SysWOW64 the other in NTI Media Maker's Program Files folder.

I thought that Windows Update was supposed to keep it updated automatically (right? wrong?)
But if WU won't keep them updated, I'd rather just ununstall them, but ... how can I tell who uses them, and what might break if I remove them.

Thanks

thank you, Jacee. I mainly wanted to figure out who depends on those particular versions so as to avoid breaking something, but I went ahead and uninstalled them via cpanel last night, and so far no problems. Thanks very much for the links.
