What if Microsoft’s email system suddenly categorized genuine emails as phishing attempts? It happened this week, disrupting businesses. Plus, 4,000 Microsoft accounts got hacked through a genuine Outlook add-in from the official Store, and we’ll reveal how attackers pulled that off. And Microsoft’s building a brand-new mini-OS in Rust to keep bad code in a cage.

This week in IT, Windows 11 adoption just jumped past 62 percent — after months of going nowhere. At the same time, Microsoft admits that barely 3 percent of Microsoft 365 users are paying for Copilot. And Redmond has reassigned senior leadership to focus on quality and security.

Administrator Protection—meant to lock down Windows 11 —was hacked in testing and forced Microsoft to rethink the design before it even ships. At the same time, Kerberos is finally saying goodbye to RC4, with enforcement deadlines that could break legacy auth if you don’t prepare. And Microsoft just gave admins a first‑party way to manage configuration drift across Microsoft 365 with new Graph UTCM APIs.

Nvidia is about to crash the Windows‑on‑Arm party. Its first PC chips could arrive with a special Windows 11 build just for new silicon. At the same time, Mandiant just made it trivial to crack a decades‑old protocol that some companies still run in production. And a new class of AI bugs shows how MCP servers can be turned into cloud‑credential vending machines.

Windows 11 just got heavier — literally. A new security update is doubling the size of critical OS files and Microsoft says it’s absolutely necessary. At the same time, the Microsoft Deployment Toolkit is quietly being killed off, pushing IT departments toward modern deployment, and this month’s Patch Tuesday unleashes 113 fixes, including a fresh zero-day already under attack.

Microsoft is bending its own rules with a special Windows update only for new AI-powered. Plus, Teams is about to start auto-blocking malware and phish by default for everyone, and if you’re migrating from Slack to Teams, Microsoft’s rolling out a new tool to make it seamless.

Meanwhile, the Windows Clipboard may soon convert anything you copy into the format you need, and Windows 11 authentication is getting a WebView2 makeover.

Could your boss soon track your every move? Microsoft is quietly rolling out a location‑tracking feature in Teams that uses Wi‑Fi and peripherals to map your office whereabouts. Microsoft is also turning up the security dial across Microsoft 365 with a new baseline that blocks legacy protocols and restricts risky file types. And if patch management keeps you awake at night, Windows Autopatch just added a CVE dashboard that shows every vulnerability and which devices remain at risk.

This Week in IT, a hidden Windows shortcut flaw exploited for years finally gets patched, but how did attackers sneak their malware past security teams? Microsoft 365 E3 and E5 customers are about to get powerful Intune tools like Remote Help and just‑in‑time admin rights—but there's a price hike on the way. And by March 2026, frontline workers will lose access to Exchange Web Services.👏 Thanks to  @Cayosoft  for sponsoring this episode of This Week in IT!#windows11 #microsoft365 #intune 🔗 Links and resources: https://petri.com/podcast/windows-shortcut-exploit-finally-patched-heres-what-it-pros-need-to-know/⌚ Time stamps00:00 - Start00:46 - Windows shortcut flaw05:09 - Intune upgrade for M365 E3 and E5 customers07:40 - EWS retirement for frontline workers
