EWF: Enhanced Write Filter
The Enhanced Write Filter (EWF) protects a volume from write access. The C:
volume of TOUCH/PPC is protected by EWF of Windows XP Embedded.
When you will setup Windows, install programs or write files on C: volume,
new data will be stored in EWF volume not in C: volume.
If you will restart TOUCH/PPC, old data will be restored in C: volume.
If you want to save new data, you must run EWF commit. Then the
TOUCH/PPC will be restart and new data will be saved.
After installing program, run EWF commit without reboot. If you
don’t, installed program will be removed.
After change Windows configuration, run EWF commit. If you don’t,
changed configuration will be removed.
After creating new files or folders, run EWF commit. If you don’t,
new files or folders will be removed.
