1、如果你已经修改了你的注册表，可以通过以管理员身份运行命令提示符恢复，按下组合快捷键“win+R”，打开“运行”窗口，输入“cmd”命令，打开命令提示符框。
2、将下列代码贴贴到命令提示符中。输入完后按下回车键。
reg add "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsSelfHostApplicability" /v "BranchName" /d "fbl_release" /t REG_SZ /f
reg add "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsSelfHostApplicability" /v "ThresholdRiskLevel" /d "low" /t REG_SZ /f
reg delete "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsSelfHostApplicability" /v "ThresholdInternal" /f
