New Win 7 User

Ran CCcleaner and registry, then ran defrag again. Same problem exists. Here is one of the files: {3d5a846b-09f3-11e0-aac1-d485649ff36c}{3808876b-c176-4e48-b7ae-04046e6cc752} it tells be it has 8 fragments and is 1,643,936KB, located in C:/System Volume Information Please tell me more about turning on/off system restore

I've just run defraggler on my new Win 7 system. It tells me there are three files left, one as large as 1.6GB, in the system folder. Tried to defrag the individual file, nothing changes. The three files are in the system information folder, and have very long alpha numeric names. Anybody have any idea what they might be, and how to get rid of them? It stumps me how I could be 7% fragmented! I'm running version 2.00.230(64bit) Thanks in advance I may be new to Win 7, but have used Defraggler for several years.
