Microsoft releases not one, but two previews of Windows 10 (build 10158 and 10159) to the Fast ring of updates in less than two days, and both builds packed a significant number of changes and improvements. Windows 10 build 10158 includes various improvements and visual changes, while build 10159 only brings at the most two visual changes: a centered login screen and the new Windows 10 “Hero” image, and around 300 bug fixes under the hood.

As such, it’s has been an exciting week for Windows Insiders, but unfortunately, not everyone is having a smooth upgrade experience, and this is not because there is a problem with the new build, instead many users are reporting issues trying to get the new preview. So, if you find yourself in this situation, there are a few things you can do to successfully upgrade to Windows 10 build 10158-10159:

Sign in with a Microsoft Account

Make absolutely sure that you’re signed in with your Microsoft Account that is registered in the Windows Insider program. Since Windows 10 build 10130 and moving forward you must be logged in with a Microsoft Account before upgrading to a new build. After the upgrade completes, you can go back to use a local account – Microsoft needs to do this to process the licensing of the operating system. You won’t see build 10158 or build 10159 on Windows Update, if you’re not singed in with a MSA.

If you know you’re signed in, but you don’t see the new build, make sure to open settings, navigate to Accounts and click the Verify button. If the buttons isn’t there, it means everything is good. In this case, restart your PC and try again.

Fix the Microsoft Account in question

It could be the case that even though everything is correct with your Microsoft Account, the upgrade won’t show up in Windows Update.

If this is the case try going to Settings, and navigate to Update & Security, click the Advanced Options link and chances are you’ll see a Fix me button. Click the button, wait a few moments, and then restart your PC and try again.

Choose the Fast ring

This may sound obvious, but most of the builds that Microsoft has released had been rolled out to the Fast ring of updates, including Windows 10 build 10158 and Windows 10 build 10159. The default configuration when installing a preview is the Slow ring, and if you changed the settings to Fast, it could also be the case that the configuration didn’t save, as such make sure to go to the advanced update options and change your settings to Fast.

Force Slow to Fast ring

If after changing the settings and selecting Fast will not save the configuration, you probably encounter a bug, and to fix this you need to change your registry settings.

Simply open the Command Prompt as an administrator and type the following command and press Enter:

reg flags HKLM\Software\Microsoft\WindowsSelfHost\Applicability set DONT_VIRTUALIZE

Then restart your PC and try again.

If the update is stuck, errors occur, or update won’t show up

There could be the case that you will get stuck at “Downloading Updates 0%”, or you could start seeing different error codes, or if you’re running a 32-bit version of the operating system the upgrade will simple not show up. In these scenarios you can try restarting the Windows Update service, which will also work for many other cases as well.

To restart the Windows Update service:

  1. Right-click on the taskbar, and open the Task Manager

  2. Click the “More details” button

  3. Navigate to the Service tab

  4. Find the wuauserv, right-click the service, and click Restart

You don’t need to restart, simply to do the upgrade again.

Last resource 

If you have tried all the instructions mentioned above, you could wait until Microsoft releases a fix for the issue, or you can opt to roll back the operating system and start over, or you could wait for build to be available through the Slow ring of updates, or you could try searching and finding the ISO files for Windows 10 unofficially – highly not recommended, but if you don’t have other choice, this could be the way, but try it at your own risk.

Wrapping things up

Microsoft is scheduled to release Windows 10 RTM on July 29th, but it appears that will see a few more builds before the end of the month, as such if you encounter an issue these instructions may help you.

If you encounter another issue and you have resolved it, don’t forget to tell us how you’d fix it in the comments below.
