Virtual Machine technology is increasingly used in daily work. Especially in the software development industry, virtual machines are used more extensively. developers generally use virtual machines in the VMware series, however, during use, we are often troubled by a problem, that is, if the virtual machine is installed on a Windows operating system, generally, you need to press CTRL + ALT + DEL to enter the user name and password before entering the system, and then enter the system. We know that if the virtual machine is installed on a Windows operating system, when the three keys are simultaneously pressed in the virtual machine, the event will be first intercepted by the external operating system, in this way, the system will first enter the locked prompt interface. Of course, you need to click "cancel" to return to the system interface. After you click "OK", the above prompt box will be removed, then you can enter the user name and password, and then enter the operating system. In this way, I feel a little uncomfortable. Is there any other good solution? Of course, it is very simple to know. In fact, this function is available in the menu of VMware, select "VM-> send CTRL + ALT + DEL" in the menu bar of VMware. Try it.
