Enabling and Disabling the File Based Write Filter Using the Desktop Icons
For convenience, use the File Based Write Filter enable and disable icons present on the
administrator desktop.
• File Based Write Filter Enable Icon - (Green) Double-clicking this icon enables the
File Based Write Filter. This utility is similar to running the fbwfmgr /enable
command line option as described in
"Running File Based Write Filter Command Line
Options." However, double-clicking this icon immediately restarts the system and
enables the File Based Write Filter. The File Based Write Filter status icon in the
system tray is green when the File Based Write Filter is enabled.
• File Based Write Filter Disable Icon - (Red) Double-clicking this icon allows you to
disable the File Based Write Filter. This utility is similar to running the fbwfmgr /
disable command line option as described in
"Running File Based Write Filter
Command Line Options." However, double-clicking this icon immediately restarts the
system and disables the File Based Write Filter. The File Based Write Filter remains
disabled and can only be enabled using the File Based Write Filter Enable icon or
through the command line as described in
"Running File Based Write Filter Command
Line Options." The File Based Write Filter status icon in the system tray remains red
while the File Based Write Filter is disabled.
