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 opera-
tions and redirects them to a special storage cache. By rebooting the operating system on the WMT,
all savings and changes will be deleted. For permanent 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. Write protection is provided only for the C: partition, the D: partition is always
excluded from write protection.
