Windows 10 Insider Preview Troubleshooting: How to Fix Update Problem from Build #16251 to #16257

Scenario: 

We are using Windows 10 Insider Preview Build #16251 and we are a Fast Ring user. Found Insider Preview Build #16257 started downloading but it never got updated to #16257 and again it switched back to #16251.

 

How To Fix :

  • If you’re having problems with Windows Update, make sure you're connected to the Internet and then download and run the Windows Update Troubleshooter .
  • If the above doesn’t fix the issue then try the following:
  • Type msconfig in Start Search box and hit the Enter key. Put a check mark against Safe boot under the Boot tab.
  • Click OK or Apply.
  • Reboot your system.
  • Boot into Safe mode.
  • Now locate C:\Windows\SoftwareDistribution
  • Select all the contents under SoftwareDistribution and delete them.
  • Once again type msconfig in Start Search box and this time uncheck the box against Safe boot under the Boot tab.
  • Reboot
  • Click Settings
  • Click Update & Security and now try to update to #16257.

Advantages of the above process:

  • You don't need to stop or start Windows Update process via elevated cmd using the following commands:

net stop wuauserv

net start wuauserv

  • As you are using Safe Mode there is no need to take ownership rights for SoftwareDistribution folder separately.
