    You surely tried to install the latest software updates that came straight out the gates at Redmond today, so let us show you what problems you could face while doing it.

    No, this update won’t brick your PC, but it will make it a bit harder than usual. And by that, we mean that you won’t be able to install KB5007651 at all.

    There’s no official response or workaround from Microsoft for the time being, so we’re just going to have to wait and see.

    Installation for KB5007651 fails with 0x80070643 error code

    Typically, your average Windows user will go ahead and install the latest Microsoft software when prompted to do so by the OS.

    Only this time, the situation isn’t as simple as we thought, because the Update Stack Package – (Version 922.415.111.0) refuses to cooperate.

    As far as we can tell this isn’t a problem that affects absolutely everyone, but a large number of users have reported dealing with this unfortunate situation.

    Pressing the Retry button located on the right side won’t help you this time, as the process itself is corrupted.

    This is not a new error code, as we have dealt with this situation in the past as well, so we can show you what you need to do in order to fix it.

    However, before trying to get rid of the update error 0x80070643, it’s worth considering the more likely causes of the issue:

    • Third-party antivirus software conflicts: Antivirus software might be conflicting with the Windows Update service
    • Missing, outdated, or corrupted .NET Framework installation: Updates fail to install because .NET Framework is corrupted or missing or you might need to install a newer version
    • Corrupted system files: You might have to repair corrupted system files causing the issue
    • Damaged Windows Update components: Some Windows Update components might be corrupted or incorrectly configured
    • Corrupted Windows Defender definitions: Error 0x80070643 can also arise because of corrupted Windows Defender definitions

    We will closely monitor the situation and keep you posted on further developments or changes that may appear as a result of this happening.
