Using an INF file to uninstall a file system filter driver

Note

For optimal reliability and performance, use file system minifilter drivers with Filter Manager support instead of legacy file system filter drivers. To port your legacy driver to a minifilter driver, see Guidelines for Porting Legacy Filter Drivers.

Starting with Windows 10 version 1903, the DefaultUninstall and DefaultUninstall.Services INF sections are prohibited (with exception).

In Windows 10 prior to version 1903, the DefaultUninstall and DefaultUninstall.Services sections were optional but recommended if the driver could be uninstalled. For these OS versions, you can uninstall your filter driver by using the command line, PowerShell, or a batch file to execute these INF file sections, or a user-mode uninstall application.

There's no "right-click uninstall" option.

Command-Line or Batch File Uninstall

To execute the DefaultUninstall and DefaultUninstall.Services sections of your INF file on the command line, type the following command at the command prompt, or create and run a batch file that contains this command:

RUNDLL32.EXE SETUPAPI.DLL,InstallHinfSection DefaultUninstall 132 path-to-uninstall-dir\infname.inf

For more information, see Rundll32 and InstallHinfSection.

PowerShell Uninstall

Type the following command at the PowerShell command prompt:

Get-CimInstance Win32_SystemDriver -Filter "name='your_driver_name'" | Invoke-CimMethod -MethodName Delete

Fore more information, see CimCmdlets.

Uninstall Application

You can also execute the DefaultUninstall and DefaultUninstall.Services sections of your INF file from an uninstall application, as shown in the following code example:

InstallHinfSection(NULL,NULL,TEXT("DefaultUninstall 132 path-to-uninstall-dir\infname.inf"),0);

If you use an application to uninstall your driver, observe the following guidelines:

• To prepare for eventual uninstall, a setup application should copy the driver INF file to an uninstall directory.
• In the DefaultUninstall.Services section of the INF file, the DelService directive should always specify the 0x200 (SPSVCINST_STOPSERVICE) flag to stop the service before it's deleted.
• If a user-mode application was installed with the driver, this application should be listed in Add or Remove Programs in Control Panel so that the user can uninstall it if desired. Only one item should be listed, representing both the application and the driver. For more information about how to list your application in Add or Remove Programs, see "Removing an Application" in the Setup and System Administration section of the Microsoft Windows SDK documentation.
• An uninstall application shouldn't delete the INF file (or its associated PNF file) from the Windows INF file directory (%windir%\INF).
• Some filter driver files can't safely be removed when the application is uninstalled. These files shouldn't be listed in the DefaultUninstall.Services section of the INF file.
