it may be one of the hotfixes you have listed there that executes MSNM at the end of the install. are any of the hotfixes for MSNM? and if you have MSNM installing or upgrading somewhere in that period of time, like a 13 min mark, make sure you have the right parameters. which you probably do. but actually, i don't know if in your case it actually hinders the install of other programs, because if it doesn't, you could just leave it up. even though i agree it would be annoying.
