Affected users can manually relaunch Windows Explorer via Task Manager as a workaround. Microsoft has released Known Issue Rollback (KIR) group policies (KB5124006 for 26H1, KB5124010 for 24H2/25H2) that IT admins can deploy to mitigate the bug on enterprise devices until a permanent fix ships. ## Full article daily.dev links to this article rather than hosting it.
