Error code 0x8007043c can be encountered while updating Windows OS. The reasons for the appearance of this problem, as a rule, are the following:
- update incompatible with the version of the system;
- interference in the process of updating a third-party antivirus;
- damage to Windows system files.
Now that we have a closer look at the problem, let’s now try to get rid of it using several proven methods.
Method # 1 Run the troubleshooter (Win 10 only)
Some users claim that they managed to get rid of error 0x8007043c using the system’s Update Troubleshooter. It’s true, such a thing is already installed in your OS, so you don’t have to download and install anything.
To use this tool, you need to do the following:
- press on the Windows keyboard + R;
- write in a blank line ms-settings: troubleshoot and press Enter;
- click LMB on the item “Windows Update”;
- click on the “Run the troubleshooter” button that appears below;
- follow the instructions on the screen.
Once you apply the solution provided by the troubleshooter, restart your computer, and then try updating your system again.
Method # 2 Disabling antivirus
Antivirus is designed to protect your computer from various virus threats. However, in some cases, non-Microsoft antivirus software may interfere with the normal operation of Windows. If you have any third-party antivirus on your PC, then we strongly recommend disabling it and then trying to update Windows again. Perhaps the 0x8007043c error occurred due to an overly caring antivirus.
Method # 3 Running DISM and SFC
If none of the above methods helped you, then you can try using DISM and SFC tools on your system. To do this, you need to follow these steps:
- press Windows + R;
- write down the value cmd and press Ctrl + Shift + Enter;
- write command sfc / scannow and press Enter;
- wait for the command to finish and restart your computer;
- open Command Prompt again;
- write DISM / Online / Cleanup-Image / RestoreHealth and press Enter;
- wait until the end of the procedure and restart the computer again.
Try updating your Windows and see if error 0x8007043c occurs again.
