interrupt - Print Screen button seems to bug check Windows when debug boot option is enabled -


I am developing some drivers on my Windows machine and I was wondering why pressing the PrtSc (print screen) button My machine seems to hang on to take a screen capture, some platforms suggest that this happens when the DEBUG boot option is set in Windows and it is a panic / bug-check in the Windows kernel .

Is this a Windows bug? Or is it really useful in some way, such as in Linux where the PrattasC / SSL is actually a kernel interrupt key?

UPDATE # 1: I am using Windows 7 X64 Professional Build 7601.

You can disable the SYSRQ key by editing the registry. In the HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ i8042prt \ Parameter Registry Key, create a value named BreakOnSysRq and set it to DWORD 0x0. Then, restart the computer After restarting the computer, you can press the SYSRQ key on the keyboard of the target computer and it will not break in the kernel debugger.

This part of the circuit will be combination logic.
