This update was part of the March 2026 Patch Tuesday cycle, so it downloaded and installed automatically.In our tests, Windows Latest observed that the March 2026 Update is decent, and it doesn’t appear to break PCs, which is a great feat if you compare the results to the January 2026 update. The January 2026 Update was a disaster for Windows 11, as it broke PCs with BSODs, triggered BitLocker, and even affected gaming performance on Nvidia GPUs.However, Windows 11 KB5079473 (March 2026 update) isn’t a great update for everyone.Microsoft told Windows Latest that the March 2026 update broke sign-in to Microsoft accounts in apps like Teams, OneDrive, and even Outlook.If you are affected and open one of these Microsoft account-based apps, you will run into an error that says, “You’ll need the Internet for this. It doesn’t look like you’re connected to the Internet”.However, it’s not as widespread as you might think, according to Microsoft.“Please note this issue occurs when the device enters a specific network connectivity state, and may resolve on its own. However, if the device is restarted without an active internet connection, it might return to a connectivity state where the issue can occur again,” Microsoft noted in an updated support document.I’ve not personally experienced internet issues after installing the update, but one Windows Latest reader told me they are unable to access Teams for the consumer app even when their PC is connected to the internet. Changing DNS, connecting to VPN, or reinstalling the apps does not help, as the bug affects the Windows installation.Microsoft confirmed that other apps, such as MS Word, PowerPoint, Excel, and even the company’s favourite Copilot, are also affected. But that doesn’t mean it’s no longer possible to use PowerPoint or MS Word.The issue affects OneDrive/cloud sync in these Office apps, and some fonts may not download. You won’t be able to download templates either.Thankfully, Windows 11 KB5085516 emergency update addresses internet connectivity issues in these apps, and you can download it from Windows Update.The post Windows 11 KB5085516 released after KB5079473 breaks internet access in popular apps, says Microsoft appeared first on Windows Latest
