i was checking out the new critical update last night @ window's update and i saw that there were 2 critical update availabe to dl.. one is the ie6 update and the other one is the windows messager 4.6 connectivity update.. since both of these updates are being placed in the critical update category, so i dl'ed and installed them.. after my computer reboots, windows message shows up when i logged into windows.. i have previously uninstall windows message already, but it was installed again in the latest windows update.. is it ok to uninstall it again, since i don't use windows messager? will it affect any other windows application?
