Symptoms

Unable to hide the taskbar in Windows when the Virtual Machine is running in Coherence mode.

Show / Hide Windows Taskbar option is greyed out under View menu.

Cause

One of Parallels Tools components (prl_cc.exe, Parallels Control Center) hasn't been launched with Windows start or DesktopUtilities.dll was not loaded.

Resolution

  1. Reinstall Parallels Tools:

    • In Windows, right-click on Start Menu (bottom left of the screen) -> Apps & features (in Windows 7: Start Menu -> Control Panel ->  Programs & features)
    • Locate Parallels Tools in the list of installed programs.
    • Click Uninstall Button to uninstall Parallels Tools.
       
    • Once the uninstallation is complete, please, reboot your Windows virtual machine.
    • Once Windows is rebooted install Parallels Tools.

  2. Check that Parallels Tools are not blocked by an antivirus or firewall software installed in Windows (if any). Add Parallels Tools to the "white list" of your antivirus/ firewall.

  3. Make sure prl_cc.exe is started and works properly:

    • Go to C:\Program Files (x86)\Parallels\Parallels Tools and start prl_cc.exe (right-click on the file -> run as administrator).

    • Check that is was started by executing tasklist | findstr prl_cc.exe in command line:

      Go to Start -> in the search type in CMD -> start CMD (command line) -> type the following and hit Enter/Return:

      tasklist | findstr prl_cc.exe

      The output should look like this:

  4. Reboot your Virtual Machine and check the issue.

    If the issue still persists:

  5. Make sure that Parallels Control Center (prl_cc.exe) is loaded on Windows startup:

    • create a shortcut of the prl_cc.exe (located in C:\Program Files (x86)\Parallels\Parallels Tools)
    • copy created shortcut to C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup directory
