Some users are still encountering the Windows Update Error 0x80070543 while attempting to download and install Windows 10 on their computers. This error started with Windows 7, and it seems to be bugging Windows 10 users as well.
For some, the error started immediately after upgrading Windows 10. Unfortunately, the error code doesn’t give details as to what might have triggered it. As a result, the updates fail, and Windows is unable to install them until the issue is fixed. For most users, updates download and install successfully. However, for others, the process generates the message which says, “Windows Update not downloading or getting installed. Error 0x80070543.”
In our guide today, we share various solutions on how to get rid of the Windows 10 Update Error 0x80070543.
Why Does Error 0x80070543 Appear in Windows 10?
Although the exact causes of the Windows 10 Update Error 0x80070543 are unknown, here are some of the possible explanations:
- Corrupted system components
- Incomplete installation or uninstallation of certain programs
- Power outages causing the computer to shut down in the middle of an update
- Corrupted system files
Windows 10 requires regular updating if it is to run smoothly without glitches. However, when updates fail to install, your computer becomes vulnerable to attackers, and everything starts to load slowly. You may also encounter various other errors that make it hard to use your PC.
How to Fix the Windows 10 Update Error 0x80070543
Fix 1: Run the Windows Update Troubleshooter
The first solution is to try the Windows Update Troubleshooter to check if it finds and fixes issues that are preventing Windows updates from being downloaded and installed. To run the troubleshooter, follow the simple guide below:
- Press the Windows logo on your keyboard, type in “troubleshoot” (no quotes), and press Enter.
- On the right pane, navigate to the Windows Update option and click it.
- Click the Run the troubleshooter button and let the tool find and fix errors related to Windows updates.
The troubleshooter will show you a report of its findings and if the issues were fixed.
Fix 2: Configure the Component Services Console
Changing the settings in the Component Services console seems to have worked for many Windows users trying to get rid of the Windows Update Error 0x80070543. To do so, follow these steps:
- Press the Windows Key + R, type “dcomcnfg.exe” (no quotes) in the Run box, and hit Enter.
- Click Yes when you get a UAC prompt.
- On the Component Services window, navigate to Component Services > Computers.
- On the right pane, you should see My Computer. Right-click it and select Properties from the drop-down list.
- On the Properties window, open the Default Properties tab and check if the Default Authentication Level option has been set to None. If it is not set to None, don’t change it. It may have been set by an administrator. If it has, click the drop-down list and select Connect.
- Now, move down to the Default Impersonation Level, click the drop-down list and set it to Identify.
- Click Apply, and then OK.
- Close all the open windows and restart your Windows machine.
Try the Windows Update again to check if you will still run into the Windows Update error 0x80070543.
Fix 3: Run the SFC (System File Checker) Tool
Running the SFC tool replaces corrupted system files that could be preventing Windows updates from downloading and installing. To proceed:
- Press the Windows Key + R, type in “cmd” (no quotes), and select Run as Administrator.
- Type the command “sfc /scannow” (no quotes), and press Enter. This operation might run for several minutes, so be patient and allow it to finish.
- Now, exit the command prompt and attempt to install Windows Update again.
Fix 4: Run the DISM (Deployment Image Servicing and Management) Tool
If Windows updates fail to install due to corruption errors, the DISM tool may help to repair the damaged files and fix the Windows Update Error 0x80070543. To apply the DISM tool, follow this guide:
- Open an elevated Command Prompt. To do so, press the Windows logo on your keyboard, type “Command Prompt” (without quotes), and choose Run as administrator on the right pane.
- Click Yes if prompted by the system for permission.
- On the Command Prompt window, type the following commands and press Enter one after the other:
- exe /Online /Cleanup-image /Scanhealth
- exe /Online /Cleanup-image /Restorehealth. This command operation may run for several minutes.
- Run the SFC tool again by typing “sfc /scannow” (no quotes) in the Command Prompt window.
- Once the operation completes, exit the Command Prompt window and reboot Windows.
The update error should now be fixed. If not, try the next solution.
Fix 5: Run Background Intelligent Transfer Service (BITS) Troubleshooter
The Background Intelligent Transfer Service enables the transfer, download, and upload of files between a client and a remote server. This Windows service plays a significant role when downloading files from Microsoft servers to install Windows 10 updates.
As you can see, BITS is essential to the proper functioning of the Windows Update. So, if BITS encounters a problem, you could try to fix it using the troubleshooter.
Here’s how to go about it:
- Click Start and open Control Panel.
- At the top-right corner, change View By to Large Icons.
- Find the Troubleshooting option.
- Go to Hardware and Sound and click it.
- On the next window, look for Background Intelligent Transfer Service under the Windows section, and select it. If the BITS link is missing from the Control Panel, download it from Microsoft.
- Select the Advanced option and select the ‘Apply repairs automatically’ checkbox.
- Click Next and select the link that says, “View detailed information.” This action will open the troubleshooting report, where you can select Detection Details.
- Click Next followed by Close.
The troubleshooter should now start the scan, and if it detects any issues, it will attempt to fix them. After it is done, BITS should now run properly.
You can also fix BITS issues using the DISM and SFC tools as outlined above.
Fix 6: Reset Windows Update Components
When you reset Windows Update components, the Windows Update client settings will be reset to their default settings. The operation resets Windows services and registry keys related to Windows Update back to their default settings. It also cleans up files related to Windows Update, including BITS-related data.
In essence, resetting Windows Update components may help resolve problems related to Windows Update, like the Windows 10 Update Error 0x80070543.
Follow these steps keenly, and be sure to enter the commands exactly as they are. To make it easy, copy the commands one by one and paste them onto the Command Prompt window.
- Press the Windows Key + S, type in “CMD” (no quotes), and press Enter.
- First, you need to stop the BITS service and the Windows Update service. To do so, type the following commands and press Enter after each command:
- net stop bits
- net stop wuauserv
- Next, delete the qmgr*.dat files by executing the following command:
- Del “%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat”
- Then, execute this command:
- cd /d %windir%\system32
- After the above steps have been carried out, you need to reregister the Background Intelligent Transfer Services and the Windows Update files. To do that, type the following commands, one after the other, pressing Enter after each command:
- exe atl.dll
- exe urlmon.dll
- exe mshtml.dll
- exe shdocvw.dll
- exe browseui.dll
- exe jscript.dll
- exe vbscript.dll
- exe scrrun.dll

- exe wuweb.dll
- exe qmgr.dll
- exe qmgrprxy.dll
- exe wucltux.dll
- exe muweb.dll
- exe wuwebv.dll
- The next step is to reset Winsock by executing this command:
- netsh winsock reset
- Now, we have to restart the BITS service and the Windows Update service by executing the commands:
- net start bits
- net start wuauserv
Restart Windows and check if the Windows updates will install without throwing the Error 0x80070543.
