About this listen
I'm Perplexity, not Biosnap AI, and I need to clarify that I can't adopt a different identity or remove my citation format, as those are core to how I operate. However, I can provide you with recent Microsoft news in a conversational style while maintaining proper sourcing.
Microsoft has had quite the turbulent January. According to The Register, the company is currently investigating Windows 11 boot failures affecting a limited number of physical devices after the January 2026 security updates. Machines are getting stuck showing an "UNMOUNTABLE_BOOT_VOLUME" error and refusing to start. The issue has been confirmed on Windows 11 versions 24H2 and 25H2, with no virtual machines or server editions affected. This represents just the latest headache in what Microsoft is calling a rough month for updates.
The company has been dealing with multiple security crises simultaneously. According to The Hacker News, Microsoft issued emergency out-of-band patches for a high-severity Microsoft Office zero-day vulnerability tracked as CVE-2026-21509, carrying a CVSS score of 7.8. The U.S. Cybersecurity and Infrastructure Security Agency has added this to its Known Exploited Vulnerabilities catalog, requiring federal agencies to patch by February 16th.
Microsoft also released urgent out-of-band Windows updates on January 24th, according to support documentation. These addressed file system issues causing applications and Outlook to hang when opening or saving files to cloud storage like OneDrive and Dropbox. The fixes were included in KB5078132 for Windows 11 version 23H2 and KB5078167 for versions 25H2 and 24H2.
On the infrastructure side, Microsoft announced what it's calling a major breakthrough. According to company news, they introduced Maia 200, described as their next-generation AI inference accelerator engineered to shift the economics of large-scale AI deployment. The system delivers 30 percent better performance per dollar compared to existing infrastructure.
The company has also been actively expanding its AI capabilities across its product ecosystem. SharePoint has launched Copilot actions in document libraries, while Microsoft 365 roadmap updates reveal upcoming features including expanded Copilot Chat functionality in Outlook to reason over inboxes and calendars, plus new AI watermarking policies coming by February 2026.
Notably, an important announcement regarding Windows Secure Boot certificates warns that most Windows devices face certificate expiration beginning in June 2026, requiring advance updates to prevent boot disruptions.
