  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.

    • 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:

      prl_cc.exe                     280 Console                    1     20,312 K

  4. Reboot your Virtual Machine and check the issue.

    if the issue still persists:

  5. Make sure 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
