This article explains how to install Parallels Tools in Windows virtual machines.
To install Parallels Tools in Ubuntu virtual machines, see KB 113394.
If you chose Express installation mode in the Virtual Machine Wizard, Parallels Tools were installed automatically after initial Windows installation.
If you opted not to use Express installation mode or if you previously uninstalled Parallels Tools, you will need to install Parallels Tools manually:
Start your virtual machine
In Mac menu go to Actions > Install Parallels Tools. In previous versions of Parallels Desktop, go to the Virtual Machine menu > Install Parallels Tools.
You will be prompted to click Continue to start the installation process.
Select Install Parallels Tools.
Click "Yes" in the User Account Control dialog box.
Installation will now start and you will see the progress bar
When installation is finished, restart your virtual machine.
