Pressing Printscrn when the driver isn't loaded (or has been unloaded) freeze the guest OS.

yes this is a well known problem: some of the debugger logic needs to be copied into KDCOM: when you press PrintScr, an INT3 is executed in the kernel: KDCOM should detect this, skip the hardcoded breakpoint and resume execution. And it should do this only when BugChecker is not loaded.
