This surge brings the company's total number of patches for the year to 2,760, more than doubling the volume recorded in the previous year.
The rapid increase in security fixes highlights an escalating "arms race" in AI infrastructure security.
Tech industry leaders, including OpenAI and Amazon Web Services, recently warned that AI-assisted tools are making it significantly easier for attackers to find and exploit software weaknesses.
By aggressively patching vulnerabilities now, Microsoft and its peers aim to secure systems before a predicted wave of automated, large-scale cyberattacks can take advantage of these openings.
Among the most urgent fixes are two "zero-day" vulnerabilities—flaws discovered by attackers before a fix was available—affecting core Windows services.
Security researchers also identified over 20 "wormable" bugs, which are particularly dangerous because they can spread automatically from one computer to another without any user action.
As AI-driven bug hunting becomes the new standard, IT professionals and everyday users face a more demanding maintenance schedule to keep their digital environments protected.
