Windows 11 Update Issues: Microsoft Releases Emergency Fix; iOS 2022 Users Get DarkSword iPhone Exploit Patch

Microsoft recently issued a series of emergency updates to resolve issues related to the March Windows 11 preview update, KB5079391. On April 1, Microsoft released `KB5086672` to fix installation problems stemming from a botched rollout (Microsoft Rolls Out Yet Another Fix for a Botched Update; Out-of-Band KB5086672 Is on Hand to Address Issues with KB5079391 ). The issue first emerged after Microsoft paused the KB5079391 preview update following reports of installation failures (Microsoft Pauses Windows 11 KB5079391 Preview Update Following Install Failures ).

In related news, Apple is taking action against a severe iPhone security exploit called DarkSword, which was made publicly available on GitHub on March 23. To protect users stuck on iOS 18, Apple is releasing a patch for the operating system, so those users can be safeguarded (Users staying on iOS 18 will get a patch for the worst iPhone attack vector we've ever seen ). This is an additional security measure, as Apple has already patched the exploit in the latest version of iOS, 26.3.

For MSFT investors, the repeated update incidents raise questions about quality assurance processes within the Windows engineering organization. The KB5079391 episode follows a pattern of Windows 11 patch complications over the past year, each requiring an out-of-band emergency fix that adds support cost and erodes consumer confidence in the platform's stability. On the Apple AAPL front, the out-of-band iOS 18 patch for DarkSword reflects Apple's continued investment in legacy OS support — a competitive differentiator in enterprise device management where iOS 18 remains broadly deployed and where any gap in security coverage could accelerate migration timelines or create enterprise IT risk discussions .
