How to upgrade Win10 Build 10061

If you have not received the Win10 Build 10061 update, first check if your computer has "Fast Ring" turned on. However, somehow, the testers of Windows 10 Build 10056 seem to have encountered problems that cannot be upgraded to Build 10061. Don't worry, here's the correct way to open it.
Specifically, because Windows 10 Build 10056 is originally only for the internal testing (leak) version of Microsoft employees, so you can only upgrade to the legendary Build 10066 (want to upgrade will undoubtedly).
To help these people who are deeply troubled by Windows Update successfully upgrade to Windows 10 Build 10061 through Windows Update, we have to sacrifice the omnipotent "Registry Dafa" again.
It should be noted that the following operations will also put you in the "Fast Ring":
• Run (WinKey+R) Registry Editor”, enter “RegEdit” and enter (requires UAC authorization);
• find "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsSelfHostApplicability";
• modify "BranchName" to "fbl_impressive";;
• will “ ThresholdRiskLevel”edited to “low”;
• Amend “Ring” to “WIF”;
• Change “ThreholdOptedin”(Dword value) to “00000001”.
Don't rush to restart, I haven't finished yet!
• Open the command prompt in admin mode (Start Menu -> Enter ‘cmd’->right click->‘ Run the administrator mode & rsquo;), then complete the following steps;
• execute “net stop wuauserv” (enter and enter, the same below);
• execute“net stop bits”;
• Execute “net start bits”;
• Execute "net start wuauserv”.
