Windows 10: 21H2 update failure

Speedrunner_349 · Aug 24, 2021

"We couldn't complete the updates. Undoing changes." -Windows 10 when updating to 21H2You heard that right. Every time I try to update my computer to 21H2, it always says that. This computer runs Windows 10 very fast. The CPU is Dell OptiPlex 790, running Windows Insider Program: Release Preview Channel. I don't know the cause, or it might be a sequel to what happened to the "Clover Trail" processors or something. Specsevice name GAMER-PC Processor IntelR CoreTM i5-2400 CPU @ 3.10GHz 3.10 GHz Installed RAM 4.00 GB 3.88 GB usable Device ID 6E7A5765-53FC-4339-892A-557149D016FB Product

Microsoft introduces the next feature update to Windows 10: 21H2

While we are excited for the next generation of Windows with Windows 11, we are also focused on supporting the more than 1.3 billion monthly active devices on Windows 10. Today, we are introducing the next feature update to Windows 10: Windows 10, version 21H2. Windows continues to play an important role in people’s lives as they continue to work, learn and have fun in hybrid and remote environments. Our goal is to provide new features and functionality via a fast and reliable update experience to help keep people and organizations protected and productive. Version 21H2 will continue the recent feature update trend of being delivered in an optimized way using servicing technology. Today I will share details on scope, how we plan to service the release and next steps.

Updated features delivered in a fast, familiar way

Windows 10, version 21H2 will have a scoped set of features focused on productivity and security, prioritized to meet our customers’ needs based on feedback. New features focused on productivity, management and security include:

Adding WPA3 H2E standards support for enhanced Wi-Fi security

Windows Hello for Business supports simplified passwordless deployment models for achieving a deploy-to-run state within a few minutes

GPU compute support in the Windows Subsystem for Linux (WSL) and Azure IoT Edge for Linux on Windows (EFLOW) deployments for machine learning and other compute intensive workflows

Given the continuation of increased PC engagement for remote and hybrid play, learning and work, we will deliver Windows 10, version 21H2 using servicing technology (like that used for the monthly update process). For consumer or commercial users with devices running version 2004 or later, the Windows 10, version 21H2 update will have a fast installation experience. As this Windows 10 release is targeted for the second half of 2021, Home and Pro editions of version 21H2 will receive 18 months of servicing, and Enterprise and Education editions will have 30 months of servicing. In addition, we will also launch the next version of the Windows 10 Long-Term Servicing Channel (LTSC) based on version 21H2 at the same time, and it will have five years of servicing as announced in February. More information can be found in my recent Windows lifecycle and servicing update, and we’ll have more news on future updates at a later date.

Next steps

Our launch approach for version 21H2 continues to fully leverage the Windows Insider Program to obtain user feedback and data insights on quality. Today we will begin releasing 21H2 builds to Windows Insiders who were moved to the Release Preview channel from the Beta channel because their specific devices did not meet the hardware requirements for Windows 11. This enables them to instead experience the latest innovations and enhancements in Windows 10 (note Insiders will not see new features noted in this blog right away, but in future Insider builds as they are ready). Broad availability of Windows 10, version 21H2 will begin later in the second half of this calendar year. We will provide more information on this release and the next Windows 10 LTSC release (including the next IoT Enterprise LTSC release) in the near term. You can always find the latest Windows servicing and update information on the Windows release health hub, now available in 10 languages. We look forward to hearing your feedback.

Windows Updated(16299.309).KB4088776 Restart is required to complete.

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.

And thanks for the tip of that program, I'll have it on my list.

Windows Update failure with error 0x80070002

Thanks Jessen,

I have tried all the steps suggested to no avail as I have been browsing all similar failures and tried the suggested solutions. The Windows Update service appears to work ok as all other updates are ok.

It may help if I someone could explain the meaning of the failure message.

When I tried the USB method it failed in a similar way suggesting that there was something wrong with the Windows Product Key. It may help that at sometime in the past the system was restored after a failure. On some forums I have seen comments that if the
key is not perfect then the upgrade will not work.
