I found a useful utility yesterday, SSnap.

Sometimes a utility like this one is the best way to find out how a setting on Pocket PC is really configured and changed.

The program takes a snap-shot of the state of PPC that is useful for monitoring of changes on PPC, e.g. those made during installation of programs.
To compare snaps of two different PPC states it is possible to use the utility iDiffCE on your PPC or any other utilities for comparison of text files on desktop PC.

What is saved in a snap:
- Contents of the registry (keys and valuess);
- Listing of the file system (folders and ffiles; for files their dates and sizes are saved, the control sum is counted up);
- State of system databases (the list, the size, number of records, date of the last update).
