If your system is configured to block the unsigned drivers installation, you will receive the 
similar message prompting you to allow installation of these drivers. Click OK, otherwise 
Parallels Tools can not be installed at all. 

9  The wizard copies tools. When finished, Update Completed screen asks if you want to restart 

the virtual machine right now. Accept the selected option and click Finish.  

Note that the virtual machine should be restarted in order that Parallels Tools function 
properly. 

In Windows NT guest OS, readmes for continuing installation of the video and audio drivers 
will be opened. Close them since re-installation of the drivers is not needed. 

 

 

To uninstall Parallels Tools in all Windows guest operating systems except Windows NT, you 
should activate the same Parallels Tools  Installer as when installing. Do the following: 

1  Select Install Parallel Tools in the Actions menu.  

2  Parallels Tools Setup wizard performs the diagnostics of the operating system and asks "Do 

you want to completely remove the selected application and 

all of its components?

" Click Yes to begin the process.  

3  After the wizard removes the tools, the Uninstallation Completed window asks if you want to 

restart the computer now. Accept the selected option and click Finish. The virtual machine 
will be restarted.  

4  After the OS is started up, the System Settings Change screen asks "Do you want to 

restart your computer now?

". Click Yes. When the virtual machine is restarted 

once more, the tools are completely uninstalled.  

Note: After uninstalling Parallels Tools and restarting the virtual machine, the guest operating 
system may display a warning that it should be restarted once more. In this case restart the guest 
operating system one more time to ensure its correct functioning. 

In Windows NT Parallels Tools can be uninstalled using standard operating system techniques.
