How to Fix 0x80070643 Error Preventing Windows 10 Users from Installing KB5043064: Workaround Solutions
Microsoft has recently issued KB5043064, the cumulative update for Windows 10 version 22H2. While the installation of this patch is mandatory, it has led to numerous issues for users following its release.
Initially, the 0x800f0831 error code prevented the KB5043064 update from being installed on Windows 10 devices, but fortunately, a fix for this bug is now available.
However, it appears that the cumulative update has encountered another problem. The 0x80070643 error is also hindering the installation of KB5043064 on Windows 10. Many users have reported struggling with this issue on Windows forums for over a week.
While some users attempted the standard sfc /scannow command to correct the issue, it did not yield any positive results.
So, how can you resolve the 0x80070643 error, which is preventing the installation of KB5043064 on Windows 10? There is a viable solution that involves repairing your device.
Here’s what you need to do:
- Download the Windows 10 Media Creation Tool (MCT) from Microsoft.
- Launch the Media Creation Tool.
- Agree to the license terms.
- Select Upgrade this PC now, and follow the on-screen instructions to complete the repair installation.
This process will repair your Windows 10 installation without deleting your personal data. Ensure you select the option to Keep personal files and apps.
The 0x80070643 error has been a recurring issue when installing updates for both Windows 10 and Windows 11. If the above solution doesn’t resolve the problem (which is unlikely), you may want to explore additional fixes for this frustrating error.
I have been trying to install this update for over a week. I have tried several suggestions, but all I get is the update reaching 20% sometimes and 100% the other but then failing to install.
