Hello, I recently finished building my first gaming computer (yay!). Everything works fine except one thing. I installed Windows 7Professional on my 64GB Crucial M4 SSD and my SSD is almost full already. It's showing as 6.41GB of free space out of 59.5GB . From my understanding, Windows 7 can take up to 20GB. The only program I installed is McAfee Total Protection and I also installed some drivers. Does anyone know why my SSD is almost full? Is there anything I might be missing? I'm totally new with SSDs.
