Write Filter Enable and Write Filter Disable Desktop Icons
For convenience, the Write Filter Enable and Write Filter Disable icons are present on the
Administrator desktop. Depending on which icon you use, you can either enable or disable
the Write Filter.
• Write Filter Enable Icon - Double-clicking this icon allows you to enable the Write
Filter using the Write Filter Control dialog box. This utility is the equivalent of running
the wtflush.exe \e command line option as described in “Write Filter Command
Line Control” on page 44. The Write Filter is enabled and the system will automatically
restart. You do not need to flush the cache first as the Write Filter is currently disabled.
The Write Filter status icon in the taskbar system tray is green when the Write Filter is
enabled.
• Write Filter Disable Icon - Double-clicking this icon allows you to disable the Write
Filter. This utility is the equivalent of running the wtflush.exe \d command line
option as described in “Write Filter Command Line Control” on page 44. This flushes
the cache and disables the Write Filter. The Write Filter remains disabled after the
system start and can only be enabled using the Write Filter Enable icon or through the
command line as described in “Write Filter Command Line Control” on page 44. The
Write Filter status icon in the taskbar system tray remains red while the Write Filter is
disabled.
Note
A message will remain on the desktop until the Write Filter disable process is
complete. Do not use the system during this time; the Thin Client will reboot
automatically when it is finished disabling the Write Filter. When the disable
action is complete, the Thin Client will boot with Write Filter disabled and be
ready for permanent changes to flash.
