Welcome to the windows_instrumentation_callback project! This application demonstrates how to intercept transitions from the kernel to user mode. It’s an easy way to see how system calls, asynchronous procedure calls (APCs), and exceptions work under the hood.
Before you start, make sure your system meets these requirements:
- Operating System: Windows 10 or newer
- Architecture: 64-bit processor
- Disk Space: At least 100 MB free
- RAM: Minimum 2 GB
- Permissions: Administrator rights may be required
To download and install the application, follow these steps:
-
Visit the Releases Page: Go to this link. You will see a list of available versions.
-
Choose the Version: Select the most recent version. Look for the latest stable release.
-
Download the File: Click on the link to download the installation file. The file will usually have an extension like
.exe. -
Run the Installer:
- Navigate to your Downloads folder.
- Double-click the downloaded file to start the installation.
- Follow the on-screen instructions.
-
Permission Prompt: If prompted by User Account Control, click "Yes" to allow the installation to proceed.
-
Launch the Application: Once the installation completes, find the application in your Start Menu. Click on it to open.
After launching the application, you will see a simple user interface. Here's how to use it:
-
Select Options: Use the provided menu to choose what you want to observe. You can monitor different types of events, such as:
- System calls
- Asynchronous Procedure Calls (APCs)
- Exceptions
-
Start Monitoring: Once you select your options, click the "Start" button to begin monitoring. The application will gather data and display it on the screen.
-
Stop Monitoring: To stop collecting data, click the "Stop" button. You can review the collected information in the main window.
-
Export Data: If you want to save your findings, click on "Export." You can choose a format to save the data for later analysis.
The application provides insights into how various calls and exceptions work in your system. Here’s a brief overview of what you will see:
- System Calls: These are functions that allow your applications to interact with the operating system.
- APCs: These are a special kind of procedure that can be executed at a specific point in time.
- Exceptions: These indicate events that disrupt the normal flow of execution, which can be caused by software bugs or hardware failures.
The data is intended for educational purposes, helping you understand Windows internals more clearly.
This is a process where your computer switches from executing kernel-level code to user-level code. It happens during system calls and can affect how applications run.
No. The application is designed for everyone, regardless of technical background. Follow the instructions, and you will be able to explore system calls.
No, the application only works on Windows 10 or newer versions.
Make sure your operating system meets the requirements. If problems persist, consider running the application as an administrator.
