My recommendation is that if you don't feel comfortable using Google, Registry editing and service starting and stopping, you might want to read a lot of messages here on this forum.
Registry tweaking and service process modification is not for the faint of heart.
Unless of course you have created a good restorable image of your Operating System boot drive.
And of course backing up any documents, pictures or other data that you would shed tears if you lost them.
