Windows Update Failed to Install With Error 0x80070643
By Timothy Tibbetts |
Windows error code 0x80070643 is an error that can appear when trying to install Windows Updates. Here are a few possible steps that should solve your problem.
1: Delete Pending Windows Updates
One of the best tricks anytime Windows Updates won't install, or gets what we called stuck, is to delete pending Windows Updates by deleting or renaming the Software Distributions folder. By removing this folder, Windows will recreate it after a reboot and begin to download any pending Windows Updates.
If you prefer, here's a step-by-step video guide on deleting pending Windows Updates.
Follow the steps at How-To Delete Pending Windows Updates. However, we're going to delete an additional folder for this particular error.
Once you've removed the Software Distribution folder, we also want to delete the catroot2 folder located at C:\Windows\System32.
Open an elevated Command Prompt or PowerShell and type each of these followed by enter.
net stop cryptsvc
md %systemroot%\system32\catroot2.old
xcopy %systemroot%\system32\catroot2 %systemroot%\system32\catroot2.old /s
Now delete the catroot2 folder and type in net start cryptsvc and reboot.
2: Run the Windows Updates Troubleshooter
The Windows Update Troubleshooter should be located under Control Panel > Update & Security > TroubleShoot > Windows Updates. If you don't see it, you can download it from MajorGeeks here.
Just run the Windows Updates Troubleshooter and follow the prompts. Typically, it's quick and asks for a reboot if problems are found.
3: Update From Safe Mode
By now you should have solved the problem, but if not we have one last Hail Mary to try. Just in case a third-party program is causing your error, let's reboot into safe mode and try running Windows Updates from there. Be sure to select Safe Mode With Networking.
