Windows 10 build 15042: How to fix install issues

If you’re still trying to download the latest Windows 10 build, but you can’t because the install process hangs, there’s no need to panic. Microsoft has officially acknowledged this build install issue and posted a quick workaround on how to fix it.

The Redmond giant confirms that this issue affects only a small percentage of users, which is a good piece of news after all.

Windows 10 build install hangs

Issue: During the 15042 install, your PC may “hang” and become unresponsive at the Windows boot logo screen
Why: One of the required install processes may initialize but not complete or timeout, thus causing the “hang”
What to do: There are no lasting effects from this issue. Please see the workaround steps below to continue with your update

Fix: Windows 10 build install hangs

1. Manually reboot your PC if it “hangs” at the boot logo during the first attempt to install build 15042
2. Allow your PC to successfully roll back to your previous OS build
3. Log into your PC and open a Command Prompt (Admin) window:

• Click Start > type Command Prompt
• Right-click Command Prompt (desktop app) in the results list > select Run as Administrator
• Click Yes to confirm
• Paste these commands into the command prompt window > press enter after each line:

reg delete HKEY_LOCAL_MACHINE\system\setup\upgrade\nsimigrationroot /f

netsh int ipv6 set locality state=disabled

reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nsi\{eb004a01-9b1a-11d4-9123-0050047759bc}\28 /f

4. Close the Command prompt window
5. Reboot your PC
6. Re-scan for updates and re-attempt the install.

Unfortunately, some Insiders report that Microsoft’s solution doesn’t always work, and despite having performed the steps listed above, the build install process still hangs.

Trying to upgrade from Build 15031. My install hangs at 23% consistently. I tried running the above commands, rebooting, rescanning and upgrading. I removed an SD card I had plugged in, and also unplugged my keyboard as was suggested elsewhere. Still hangs at 23%.
