The F8 key is a function key that is commonly used to enter the Windows startup menu. In some instances, the F8 key is used to enter Windows safe mode.
At times, the F8 key is used to access the Windows recovery system. Using the F8 key to access the recovery system may require a special installation disc if the computer doesn't have the function automatically installed. In a Mac OS system, the F8 key displays a thumbnail image for all workspaces. The F8 key does not have a specifically assigned Windows default function, and the function varies by the user's preference.
