File-Based Write Filter (FBWF) / Unified Write Filter (UWF)
FBWF (Windows 7 Embedded) / UWF (Windows 10 IoT) is a Microsoft driver that
saves all I/O operations and redirects them to a special storage cache. By rebooting
the operating system on the WMT all savings and changes will be deleted. For per-
manent savings it is needed to disable the FBWF/UWF. Switch dropdown to „disable”
then click on save and restart the WMT.
Exceptions causing loss of savings / changes are possible by choosing a folder which
will not get affected by the FBWF. By default is „C:\DATA” not affected. For adding a
new / additional folder or file click on „Add folder” / „Add file”.
