I needed to know what kind of information was stored into the RAM of my server when users were logged in. Accessing the content of the entire memory at a specific time is possible for example when Windows crashes.
So, how to make Windows XP crash ?
I first thought about coding some weird and ugly stuff which would make the system hang out and crash but...it's harder than I thought : )
Eventually, I came upon a Microsoft KB article
for activating a feature called 'Crash on Control Scroll'. This feature allows a user to manually crash the system, thus triggering the blue screen of death (also known as BSOD) and memory dump generation.
To enable that feature on a USB keyboard:
- Start the registry editor (regedit.exe)
- Locate the following key if you have a USB keyboard: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServiceskbdhidParameters
- Locate the following key if you have a PS2 keyboard: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesi8042prtParameters
- In the Edit menu, click Add Value and add the following registry entry: Name: CrashOnCtrlScroll
Data Type: REG_DWORD
- Exit the registry editor, then reboot.
After the reboot, you can now manually trigger a crash by pressing the SCROLL keyboard key twice while pressing the right CTRL key.
