How to display current value of a specific variable which is located in particular _KTHREAD object?
In Windows, you can display the current value of a specific variable that is located in a particular _KTHREAD
object using kernel debugging tools such as WinDbg or KD.
Here are the steps to display the current value of a specific variable in a _KTHREAD
object using WinDbg:
Launch WinDbg and attach it to the target process or kernel using the
File -> Attach to a Process
orFile -> Kernel Debug
menu option, respectively.Load the appropriate symbol files for the target operating system and any relevant kernel modules using the
File -> Symbol File Path
menu option.Switch to the
Processes
orThreads
view using theView -> Processes
orView -> Threads
menu option, respectively. Locate the desired_KTHREAD
object in the list.Right-click on the
_KTHREAD
object and selectProperties
from the context menu.In the
Properties
dialog box, switch to theVariables
tab. Locate the specific variable you are interested in and select it.The current value of the variable will be displayed in the
Value
field. You can also modify the value of the variable using this dialog box.
Note that kernel debugging requires advanced knowledge of Windows internals and should be done with caution. It is intended for use by developers and system administrators who are familiar with the debugging tools and techniques involved. It is also important to note that kernel debugging may affect the stability and performance of the system being debugged, so it should be used only in controlled environments.
