外媒对Win10技术预览版深入挖掘后发现只需要简单修改注册表项就能获得更多更新选项，允许用户访问和下载还未正式公布的系统版本。今天微软最新任命的Windows Insider预览项目负责人Gabriel Aul今天在推文中表示一旦进行修改，你的设备将不会接受未来的版本更新。
在推文中Aul引用了外媒NeoWin对注册表内容修改的文章报道，推文中写道：“贴士：如果任何人在Windows10上做了这样的修改，事实上就是关闭了设备获得更新的能力。”
如果你希望恢复你的注册表，微软Answer论坛提供了相应的解决方案：
If you did change the registry keys a refresher on what they should be is as follows:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability
BranchName = fbl_release
ThresholdRiskLevel = low
ThresholdInternal =
ThresholdOptedIn =
You can use these commands from and Admin Command prompt (Windows Key + X, select Command Prompt (Admin))
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
