Windows Exploit Suggester is a tool that analyzes a target's patch levels against the official Microsoft vulnerability database to detect missing patches. It also alerts users about available public exploits and Metasploit modules for the missing security bulletins.

This is an enhanced version of the original AonCyberLabs/Windows-Exploit-Suggester with modernized functionality and improved performance.

• Replaced xlrd with openpyxl: Supports modern .xlsx file formats.
• Switched to requests for HTTP downloads: More reliable than urllib.
• Improved error handling and logging: Provides clearer messages with alert levels.
• Fixed CSV parsing issues: Prevents IndexError crashes.
• Enhanced performance: Uses list comprehensions and optimized data handling.
• More readable and maintainable: Simplified function logic for better usability.

This updated script runs seamlessly on Python 3.8+ and can efficiently download and analyze the latest Windows security bulletins.
