System administrators are deeply troubled by specific blue screen errors. Recently, an automated repair method has emerged, which can indeed save a lot of manpower and time.
Root cause and impact of the problem
Recently, blue screen errors caused by specific driver files (C-.sys) have been frequently seen on many Windows 11 computers. This error prevents the system from entering the desktop normally, but is stuck in the recovery interface. This seriously affects the normal work of different users of enterprises and individuals. Manual processing one by one is inefficient. When there are a large number of devices or they are widely distributed, this work is almost difficult to complete in time. Therefore, looking for a solution that can perform batch and automated deployment has become an urgent need for IT administrators.
The core idea of automated patching
The core idea of the new approach is to contain the repair operation into a bootable pre-installation environment (WinPE) image. The specific operation method is to use script commands to automatically find and remove the C-.sys file causing the problem when WinPE starts. In this way, the administrator does not need to log in to the problematic systems one by one to perform manual operations. The essence of this idea is to transform a complicated manual repair process into a standardized boot image that can be run automatically.
dism /Mount-Wim /WimFile:"C:PathToWinPE.wim" /index:1 /MountDir:"C:PathToMountDir"
Preparation and environmental requirements
To implement this method, you need a basic environment, which is the Windows Assessment and Deployment Kit, also known as ADK. Administrators need to download and install the ADK from Microsoft's official website to obtain the necessary toolset, especially the deployment image service and management tools, also known as DISM tools. At the same time, you must prepare the original WinPE image file, which is WinPE.wim, and plan the working directory path used to mount and modify the image.
cd "C:PathToMountDirWindowsSystem32"
Specific steps to modify the WinPE image
del C:WindowsSystem32driversCrowdStrikeC-00000291*.sysexit
Use the DISM command to mount the original WinPE.wim image to the specified working directory. Then, create a batch file, that is, a .cmd file, in the mounting directory. The contents of this file must include deletion of C – *.sys file command, after creating and saving the .cmd file, use the DISM command again to uninstall the image, and the system will save all modifications on its own. At this point, a new WinPE boot image integrated with the automatic repair script is complete.
Batch network deployment via PXE
dism /Unmount-Wim /MountDir:"C:PathToMountDir"/Commit
For organizations with a large number of computers that need to be repaired urgently, the most effective method is to deploy a network boot (PXE) server, place a modified WinPE image on the PXE server, and configure the boot service properly. All affected computers were then set to boot from the network so that they would automatically load this "repaired" version of WinPE from the server. After startup, the preset script will automatically perform the deletion operation. After the operation is completed, the computer can restart normally and enter the system.
Extension methods for handling encrypted devices
If the affected computer has encryption features such as BitLocker turned on, the above process may need to be adjusted. After WinPE starts, you can first use the manage-bde command with a recovery key or password to unlock the encrypted system volume. After unlocking and accessing the partition where the system files are located, then navigate to the system directory and execute the command to delete the problematic files. This adds a few steps, but makes the solution also effective for encrypted devices.
