Unable to assign any key combination on Mac side to CTRL+BREAK on Windows side

  • Parallels Desktop 7 for Mac Standard Edition

My Mac keyboard does not have a BREAK key, but I need CTRL+BREAK key in my Windows virtual machine.
In Parallels Desktop menu, when I go to Preferences → Keyboard and try to create an assignment, there is no option to assign something to CTRL+BREAK on Windows side.


Assigning key combinations to CTRL+BREAK is not supported by Parallels Desktop.

CTRL+BREAK will work when used from Parallels Desktop status bar.


  1. Stop your virtual machine
  2. Make sure there is a USB Controller device in your virtual machine Configuration → Hardware tab. Createitifnecessary;
  3. Go to the virtual machine Configuration  Hardware tab and click on Boot Order in the list on the left. In the Boot flags: field add the following string: 


 That will enable a virtual USB keyboard in your VM which does not distinguish between BREAK and PAUSE keys. Now you may assign some combination to CTRL+PAUSE and it will be triggering CTRL+BREAK inside the virtual machine.


Purchase a PC keyboard with a BREAK key.
