Windows 11 Update KB5083769 Causes BITS Failures and System Freezes

The April 2026 cumulative update KB5083769 for Windows 11 has led to widespread issues with the Background Intelligent Transfer Service (BITS) and SOAP downloads. Users report that after installing the update, their applications experience download timeouts and the bitsadmin command freezes. Affected users have confirmed that both download methods fail, with the only temporary fix being a system reboot. However, the problem reoccurs after the system is idle for a period of time. Uninstalling KB5083769 resolves the issue entirely. Reports indicate that this problem is not isolated, affecting multiple users across different hardware configurations. Microsoft has not yet acknowledged the issue, and users are seeking guidance on how to address it. The situation mirrors past BITS-related issues that were later resolved by Microsoft.

Key Points: • KB5083769 update causes BITS and SOAP download failures on Windows 11. • Affected users experience system freezes and timeouts with the bitsadmin command. • Uninstalling the update resolves the issues, but Microsoft has not acknowledged the defect.
