# Configuration: Enabling Kernel Mode Driver

To gain full access to system information and overcome potential permission restrictions, especially when trying to inspect protected system processes (like `csrss.exe`, antivirus processes) or dealing with modern Windows security features (Windows 11+), enabling System Informer's **Kernel Mode Driver** is often necessary and highly recommended.

1. **Download and Install:** Obtain the latest version of System Informer from the official source (`https://systeminformer.sourceforge.io/`). Ensure you download the setup or binary files, not just the source code.
2. **Run as Administrator:** **Always** launch System Informer with administrative privileges (Right-click -> Run as administrator). This is required to install and utilize the kernel driver and access all process information.
3. **Access Options:** Once running, navigate to the main menu: Hacker > Options.
4. **Enable Kernel Driver:** In the Options window, go to the *General* tab. Find and check the box labeled *Enable Kernel-Mode Driver*. Click OK.
5. **Restart System Informer:** Close the application completely and restart it again *as administrator*. The kernel driver should now load (you might see a brief UAC prompt or notification). If you encounter errors stating the driver couldn't load, it might be temporarily incompatible with a very recent Windows security update (developers usually update it quickly) or blocked by aggressive third-party security software.
