Here's how to make a rock-solid Windows DAW:

1. Format hard drive
2. Reinstall Windows (From a legit copy)
3. Update Windows completely (DO NOT go to any website other than windowsupdate.microsoft.com)
4. Install all drivers, making sure all hardware is compatible (Only go to hardware manufacturers' websites if you need drivers, do not use a search engine)
5. Install Live (A legit copy)
6. Install any other applications you need. (NO BETAS OR PIRATED SOFTWARE)
7. Create a backup of the drive using your favorite software. Store in a safe place.
8. Take the network card out of the computer and never put it on the internet again.
