You heard Microsoft released a new preview of Windows 10 (build 10041), you rushed to Windows Update, after changing your update settings to get builds faster, and after clicking “Check for updates”, the operating system doesn’t seem to find the build 10041. Now this is a problem…

If you’re already in the Fast ring and checking for updates doesn’t seem to find the update, one thing that is recommended is to make sure the Flight Registry Settings are correctly set. Sometimes, these settings will not get configured correctly and you won’t be able to download new builds, but luckily there are two options: the first option involves on installing KB3038930 or, if you still have the same issue, option number two is to manually edit the registry to fix the problem.

Fix Windows Update when it can’t find build 10041

Option 1: Install the Windows Update that will reset your Flight Registry Settings

You can download the update directly from the Microsoft Update Catalog: 

  • At the Microsoft support page download update KB3038930 (32-bit or 64-bit).
  • Use the Windows key + I keyboard shortcut to open the Settings app.
  • Click Update & security.
  • Click Windows Update.
  • Click the Advanced options links.
  • Make sure your PC is in the Fast right.
  • Go back to Windows Update and click Check for updates again.

Option 2: Edit the Windows registry

If for any reason, you’re unable to install the update, you can edit the registry manually:

At the Microsoft support page download update KB3038930 (32-bit or 64-bit).

Use the Windows key + I keyboard shortcut to open the Settings app.

Click Update & security.

Click Windows Update.

Click the Advanced options links.

Make sure your PC is in the Fast right.

Go back to Windows Update and click Check for updates again.

  • Open the Start menu, do a search for regedit and open the registry as an administrator.
  • Browse the following path:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability
  • Make sure the following values exist: {value name}, {value type}, {value data}
  • BranchName, REG_SZ, fbl_impressive
  • ThresholdOptedin, REG_DWORD, 1
  • ThresholdRiskLevel, REG_SZ, low
  • Delete all other values
  • Use the Windows key + I keyboard shortcut to open the Settings app.
  • Click Update & security.
  • On Windows Update, click Check for updates.

Keep in mind that option one should be enough to get Windows 10 build 9926 to see build 10041, but there is always a chance that the update to fix the issue may not work. If that’s the case, option two should fix the problem.

Open the Start menu, do a search for regedit and open the registry as an administrator.

Browse the following path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability

Make sure the following values exist: {value name}, {value type}, {value data}

  • BranchName, REG_SZ, fbl_impressive
  • ThresholdOptedin, REG_DWORD, 1
  • ThresholdRiskLevel, REG_SZ, low

Delete all other values

On Windows Update, click Check for updates.
