Would just like show everyone a workaround that requires no extra software:
Open chrome dev tools (ctrl shift i) and navigate to sources tab, expand scripts on the left and open 'main.js'
Navigate to line 52885 and paste this code on that line:
var codes = ['ctrl', 'alt', 'del'];
MKSService.sendKeys(scope.moid, codes);
press ctrl+s to save the document, it will freeze for 30 seconds, then while the VM monitor is open, click on the fullscreen icon and ctrl alt del will fire.
after doing this, install vmware tools then use the other ctrl and del option under actions
