By checking for new hardware and updating drivers, you can often resolve the UNEXPECTED KERNEL MODE TRAP error in Windows 10/11.
python
import os
import subprocess
def analyze_event_logs():
# Clear the existing event logs
subprocess.run(['wevtutil', 'cl', 'System'])
# Trigger a BSOD unexpected kernel mode trap error
# This is just a sample method to simulate the error for demonstration purposes
trigger_bsod()
# Retrieve the event logs related to the BSOD error
subprocess.run(['wevtutil', 'qe', 'System', '/q:"*[System[Provider[@Name=\'Microsoft-Windows-Kernel-Power\'] and (EventID=41)]]"'])
# Analyze the event logs to identify potential causes
def trigger_bsod():
# Sample method to simulate a BSOD error by dividing by zero
x = 1 / 0
# Call the function to analyze event logs
analyze_event_logs()
Please note that this code is just a basic example and may not cover all possible scenarios or be a complete tool. Additionally, triggering a BSOD error intentionally is not recommended on a production system. This example demonstrates the usage of the `wevtutil` command-line tool available in Windows for querying event logs.
