Go to your start menu. (click start, duh) Then click on Run. In the Run line type: services.msc /s then hit enter/return. (note, must have that space after msc) A block will pop up. Close that damn "Messenger Service" ad that just popped up again and, then in the block that opened, to the right, there will be a list of "services". Scroll down that list until you see 'Messenger'. Double click on that. In the block that opens there, There will be an area that says "Start up Type". Click the drop down arrow to the right of that and select DISABLE!!. Click on "Apply" down below, then "Ok". Close everything out and you are done! Those biatches are gone for good now!!
