I've decided (currently) not to install it. I was told that disabling certain background services could lead to system instability, depending on when and if those disabled services were called upon during it's use.
However, I've also been told that the application can be configured to selectively pause bgd services. I don't know if this would be any different than disabling them... so the jury is still out as far as I'm concerned.
Just my opinion. I don't consider myself particularly "computer-savvy", but know enough to possess a healthy dose of paranoia. lol. ;)
Bottom line for me: I still haven't learned enough about it to trust that it would be consistently effective, and not cause longrange headaches. Besides that, I don't think that it would help with any of the server issues that have yet to be acknowledged/addressed.
