Microsoft has released an emergency update to fix some bugs that it accidentally introduced through the regular Windows update.

On June 14, the company released KB5014697, a cumulative update that fixes several known Windows issues. However, the patch also introduced new flaws, namely issues with the login process for Azure Active Directory as well as Microsoft 365 on Arm devices.

Additionally, the patch broke Wi-Fi hotspot (opens in a new tab) functionality on some devices and prevented some .NET applications from opening.

Out-of-band (OOB) updating now fixes the issue for Windows 10 and Windows 11 devices. It will automatically download and install via Windows Update, but users can also do it manually via Update Catalog, it has been clarified. .

Fixes and mitigations

"Addresses a known issue that only affects Windows Arm devices and may prevent you from signing in with Azure Active Directory (AAD)," Microsoft said in its advisory (opens in a new tab). "Applications and services that use AAD to connect, such as VPN connections, Microsoft Teams, and Microsoft Outlook, may also be affected."

Fixed one version of Windows 11 (21H2) and three versions of Windows 10 (21H2, 21H1, and 20H2).

“This OOB update is cumulative. If you are using updates released before June 14, 2022, we recommend that you install this OOB update instead of the June 14, 2022 security update,” the society says again. "If you have installed previous updates, only the new updates contained in this package will be downloaded and installed on your device."

As usual, sysadmins who can't fix it so quickly can apply a workaround: switch to web versions for certain applications.

"To mitigate the issue, you can use web versions of affected apps, such as OneDrive, Microsoft Teams, and Outlook.com," Microsoft said.

For .NET Framework issues, Microsoft recommends re-enabling the tool, while for Wi-Fi, the company suggests disabling the Wi-Fi hotspot feature.
