I have some family members that call me for "tech support" on their windows PCs. I am running W7 64; they are running W7, W8 and Vista
Years ago, I used to use Windows' built-in "little green man" to take control of their PCs, but as I recall, if they were behind a router, that often caused problems. Don't know whether that is still the case.
What are you gurus using to support your friends/families that need you to take control of their windows PCs remotely and pros/cons?
