Microsoft recently addressed several bugs related to the Windows 11 January 2026 Update. The company acknowledged a total of three major issues affecting users, primarily concerning Remote Desktop connections, shutdown functionalities, and Outlook performance.
Key Issues with Windows 11 January 2026 Update
- Remote Desktop Connection Failures: Users reported failures when attempting to connect via the Remote Desktop feature from the Windows App, specifically after installing Windows 11 25H2 updates.
- Shutdown Bug: Some older PCs running Windows 11 version 23H2 with Secure Launch enabled experienced issues where attempts to shut down or hibernate resulted in unexpected reboots.
- Outlook Crashes: A significant bug was identified that caused Outlook Classic to crash when using POP accounts, yet this issue remains unaddressed in the latest fixes.
