KB5016138 and KB5016139 fix the login bug in Windows on ARM

Earlier this month, Microsoft released the cumulative patches for all supported Windows versions. But along with fixes, Patch Tuesday introduced two bugs, the broken Hotspot and sign-in process for Microsoft 365 and Azure Active Directory. New out-of-band patches KB5016138 and KB5016139 aimed to fix the login bug.

The patches come with the following statement:

Microsoft is releasing Out-of-band (OOB) security updates today, June 20, 2022, only for Arm-based Windows devices. This update addresses a known issue that only affects Windows Arm-based devices and might prevent you from signing in using Azure Active Directory (AAD). Apps and services that use AAD to sign in, such as VPN connections, Microsoft Teams, and Microsoft Outlook, might also be affected.

Important This issue only affects Windows devices that use Arm processors. No other platforms will receive this out-of-band update. This OOB update is cumulative. We recommend that you install this OOB update instead of the June 14, 2022 security update for affected devices.

Microsoft has released the patches via Windows Update, so Windows on ARM users will receive them automatically.
