though if its the earlier version (msn messenger) you want to remove then you have to click on "add or remove windows components" at the left on the add remove programs window and remove that from there
Thanks ChuckFickens, could it be windows live essentials. I have uninstalled the earlier version now, like you said. The reason I want to do this is I can no longer use my webcam since updating to the new version so I thought if I uninstalled and started again it might resolve the problem.
