Hi
I am also a techi and majority of times its stop half the services (non microsoft) and 80% of startup items - maleware remove - done
PC works like new.
But there is the risk of disiabling something that the User does use! For eg A picture viewing client, banking software, driver related 3rd party.
So a good technician would actually take the time to individually clean and optimize a computer per customer. As it is a - Personal Computer.
All I wanted to say is.... wait for it.... AWESOME Software!!!
Thanks Piriform
