Microsoft has acknowledged that recent Windows updates, including August 2026 preview builds and this month's Patch Tuesday releases (KB5120996, KB5120998, KB5124008, KB5122880), can cause black screens after sign-in and Windows Explorer crashes. The issue mainly affects Azure Virtual Desktop hosts using FSLogix profile software. Microsoft has issued a Known Issue Rollback fix for enterprise admins and suggests manually relaunching explorer.exe as a temporary workaround for individual users.
