In the defrag mode, there are 4 defragmentable areas indicated: my C drive, D drive, and E drive defrag properly, but the "system " will not defragment. Was 5%, then 6%, and is now 7% fragmented. What's going on? Anyone else have this proplem? What's the solution?

With my Windows 7 system, after entering defrag, I am given a window containing 4 possible disks to defrag:
It is this "system" disk that does not defrag when selected for such. I am baffled. Help?

The built-in defragmenter will not defrag system files because they are in use while windows is running.
The partition keeps getting more fragmented because as the system is used, it saves Volume Shadow Copies from which to restore. These fragment (like most files do in windows and other OS's as well) so you get more fragmentation.
To defrag the system files, you need to use a third party program that will do a "Boot Time" defrag. But be careful that you get a good third party program as I have seen where computers keep re-starting after an attempted boot time defrag gone bad.
Here is a Top 10 Reviews side-by-side comparison of the best third party defrag programs available:
