July 2026 Patch Tuesday was record-setting in so many ways. The sheer volume of security patches for almost every product in the Microsoft portfolio was the highest ever and, of course, well over 600 CVEs were identified in the Security Updates Guide. Interestingly, only two CVEs were reported as exploited zero-days and only one as publicly disclosed, but we’ll get back to that later in this article.
