若註冊表更新通道設定錯誤導致無法接收更新，以管理員身分執行命令提示字元，貼上以下指令恢復預設值：

reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability" /v "BranchName" /d "fbl_release" /t REG_SZ /f
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability" /v "ThresholdRiskLevel" /d "low" /t REG_SZ /f
reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability" /v "ThresholdInternal" /f
reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability" /v "ThresholdOptedIn" /f

還原後註冊表應如圖所示。恢復預設可提升系統穩定性、修復更新問題。
