Windows 8 Task Manager RAM Usage Accuracy

memorywindows 8

The new Task Manager has a great UI in windows 8, however, there are some discrepancies in the data I can not account for:

Machine: 8 GB of total ram. (This is a physical machine, not a virtual)

The processes tab shows 45% of Memory utilized. The listed process do not add up to 3.5 GB of RAM, but instead add up to 0.948 GB. There is no "processes for all users" option.

The performance Tab Shows:

In use : 3.6 GB
Available: 4.4 GB
Committed : 4.1 /9.2 GB
Cached: 3.7 GB
Paged Pool: 376 MB
Non-paged pool: 135 MB

My reading of this says I have ALOT of "cloaked" processes running some where eating my ram.

How do I interpret this data and how do I verify it?
