Anyone remember when we used to use the K-lite Codec pack? Anyone remember the issues installing all those codecs would give your machine? (If you've only ever used VLC, you don't remember.) Driver programs are similar. There might be some out there that do what they say, but it's a risk I would really not take. Not when you can just go to the manufacturer's webpage and just install any needed driver. Why install a program and blindly hope it's doing the right thing? If it works for you, great. But I personally would NEVER suggest to someone to install a program like that on their machine.

Keep in mind they need to make money somehow. If you want pop ups for something you could have done for free that's your call. Again, I'd never suggest using one. (This might not be the same program you use, but this is common for that type of program.)
