Microsoft has acknowledged that some users may experience desktop loading issues, specifically black screens, after installing the August 2026 preview updates and subsequent releases. This problem mainly affects Azure Virtual Desktop (AVD) hosts using FSLogix. Symptoms include a black screen post-sign-in and crashes related to Windows Explorer, which can be temporarily resolved by manually launching Windows Explorer through Task Manager. For enterprise customers, Microsoft has introduced a mitigation strategy via Known Issue Rollback (KIR), allowing IT administrators to reverse problematic updates by applying specific group policies. Additionally, Microsoft has addressed issues related to the loss of mouse and desktop settings on certain Windows 11 systems caused by the KB5120998 update.
