The default settings for the Unified Write Filter (UWF) servicing screen saver can be changed through the Windows registry to use custom text, title, font, and color settings.

The UWF servicing screen saver (UwfServicingScr.scr) is located in the \Windows\System32 folder.

Important

When UWF is installed on your device, when you right-click on the Desktop, and then click Personalize > Screen Saver, the UWF servicing screen saver will appear in the list of available screen savers in the Screen Saver Settings dialog box.

Do not select UwfServicingScr as the screen saver and then click Preview, as you will not be able to exit the UWF servicing screen saver by moving the mouse or pressing a key. The only way to exit the UWF servicing screen saver in this case is by pressing the Ctrl+Alt+Delete keys.

Modify the default registry settings for the UWF servicing screen saver

  1. To modify the default registry settings for the UWF servicing screen saver, from the example shown here, change the values in a text editor, and then save as a .reg file (for example, Overridescreensaver.reg).

    Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows Embedded\ServicingScreenSaver]
"ColorBackground"=dword:000000ff
"ColorText"=dword:0000ff00
"ColorProgress"=dword:00ff0000
"ScreenSaverTitle"="Device"
"ScreenSaverSubTitle"="Servicing device…"
"HideScreenSaverText"=dword:00000000
"HideScreenSaverProgress"=dword:00000000
"Font"="Algerian"

  2. On the device, open a command prompt as an administrator. For Windows Shell, to open a command prompt, do the following:

    1. In Windows Explorer, move to \Windows\System32, right-click cmd.exe, and then click Run as Administrator.
    2. Accept the UAC prompt.

  3. To apply the custom registry settings for the screen saver to the device, type the following command:

    regedit.exe /s overridescreensaver.reg

The next time the device enters UWF servicing mode, the UwfServicingScr.scr screen saver will use the custom settings.
