I was just wondering what the best converter is for video, picture and audio files to any other format? I don't just mean freeware programs, commercial programs too. What's the best program to remove drivers as well?
Wow, very broad question. With a little research, you'll find there are plenty of encoders available for both audio and video. Asking such a question will only result in a list of different ones, and no clear favorite. So, check them out yourself and find what works best for you.
As for the driver removal tools, you don't need one. Uninstalling drivers properly can be done inside of Windows.
