I’d love to help, but doesn’t appear to match any known Windows update as of my knowledge cutoff (June 2025) or current available data.
It’s possible there’s a typo in the KB number. Microsoft’s KB (Knowledge Base) IDs are typically 6 or 7 digits, but sequences like “505xxxx” aren’t common in official Windows 10/11 or Server update history (most start with 500–504, 502–503, etc.). kb5053598
