“Perfect and simple Pros: This is the only sensible option for disabling/remapping ANY keys, although I use it for the NumLock key. No programming degree or registry editing required. Cons: I can't think of a con.
Summary: I Googled "disable Numlock" and could only find programming alternatives. I then tried searching with CNET. Bingo! Quick download and I literally had it working in under 45 seconds. [Key Remapper]”
