For information on Windows update terminology, see the different types of Windows software updates.

General Purpose

This OOB update includes quality improvements. This update is cumulative and includes security fixes and improvements from the January 13, 2026, security update (KB5073455) and the out-of-band update (KB5077797) from January 17, 2026, in addition to the following:

After you install the January 2026 Windows security update (KB5073455), you might experience the following issues, which are resolved by this OOB update:

[File System] Fixed: After installing the Windows update released on and after January 13, 2026, some applications became unresponsive or encountered unexpected errors when opening files from or saving files to cloud-based storage, such as OneDrive or Dropbox. In certain Outlook configurations that store PST files on OneDrive, Outlook may hang and fail to reopen unless the process is terminated or the system is restarted. Users may also see missing sent Items or previously downloaded emails being re-downloaded.

General Sentiment

This OOB update is meant to address several major issues that were introduced by the previous emergency updates KB5077744 and KB5077797. While those updates were intended to fix problems, they ended up causing further disruptions for many Windows 11 and 10 users.

The new KB5078132 update aims to resolve the file system and cloud storage related problems that emerged after the January 13th security update. This should help restore stability and functionality for affected applications and services like Outlook.

However, the update does come with a known issue on Windows 11 where the password icon on the lock screen may be missing or invisible. Microsoft has provided a workaround for this, but it's still an inconvenience that some users may encounter.

Known Issues

• Some devices with Virtual Secure Mode enabled might fail to shut down or hibernate
