I have discovered this,....is it reliable?
I don't know enough about the registry to tell you whether or not that hack is reliable. My guess is that even if it is, it'll also disable your
ability to download files.
However, and far more importantly, you really should NOT
mess with your registry unless you have enough proficiency to know EXACTLY
what you're doing. You could easily crash your computer and do a great deal of damage. (Please excuse the shouting, but making any kind of changes to your registry is a very serious matter.)
My best advice is that you follow the recommendations already given to you here by two very knowledgeable moderators.
