How to Fix Windows 10 Update Error 0x800705B3

We agree; installing Windows updates is no fun. And the process becomes even more daunting when your screen displays unknown errors every time you try to install the latest updates.

One such frustrating error that pops up when users attempt to install the latest webcam driver and Bluetooth adapter driver updates is the Windows 10 Update error 0x800705B3. 

This issue can be caused by a number of reasons, including corrupt system files, broken Windows Update components, TCP / IP inconsistency, and generic Windows updates inconsistency. 

If you are facing a similar issue, you are in the right place because in this guide, we are going to walk you through the relevant troubleshooting steps in detail. 

Let’s get started.

1. Run the Windows Update Troubleshooter. 

If your screen displays the Windows 10 update error 0x800705B3 upon your attempt to install a pending Windows update, then the first thing that you should do is run the Windows Update Troubleshooter. 

It is common for updates to fail to install because of bugs and corruption errors within the operating system. The troubleshooter will not just help you identify the issues but will also resolve them with little to no user input. 

Here is what you need to do:

  1. Press Windows + R keys simultaneously on your keyboard to open a Run dialogue box.
  2.  Inside the text field of the dialogue box, type control.exe and hit Enter.

  2.   Checkmark the box against Apply repairs automatically, and then click on Next.

  1.  Now, wait for the troubleshooter to complete the scanning. If the troubleshooter detects any issues, it will suggest fixes. Click on Apply the fixes to complete the process.

That’s it. 

If a corruption error or a bug within the system was causing the issue, troubleshooting will resolve it. We also have listed another easy method of removing corruption errors from your system in Method 6. Check it out if the troubleshooter fails to detects issues.

2. Install Pending Update Manually. 

There are times when the Windows Update components start acting up due an inconsistency within the system. This prevents the users from installing drivers updates and hence, the error. 

An easy way to fix this issue is to install the required update manually using the Microsoft Update Catalog. 

This method will take some time, but several users managed to escape the error at hand by installing the updates manually, which is why we suggest giving it a shot. 

Here is what you need to do:

  1. Visit the Microsoft Update Catalog website and search for the update that you want to install. 
  2. To install the update, click on the Download button against your required update and wait for the process to complete. 
  3. Once the file is successfully downloaded, open it and follow the on-screen instructions to complete the installation process.

Doing so will help you install the update without any problems. 

3. Run SFC and DISM Scans.

Like the Windows Troubleshooter, there are several other built-in troubleshooting utilities that allow the users to scan their system and fix potential issues. 

Two such easy-to-use utilities are the System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tool. 

As the name suggests, SFC scans the system’s protected files for issues while DISM looks for issues within the whole operating system. If any issues are identified, these tools will resolve them, leaving Windows error-free. 

Here is how you can run the SFC and DISM scans on Windows 10:

  1. Type cmd in the search bar and click on Run as administrator to launch elevated Command Prompt. 
  2. Inside the Command Prompt window, type the command mentioned below and hit Enter to execute it. 
sfc /scannow
SFC command DISM
  1. If the System File Checker detects issues, it will resolve them. However, if you are still facing the error, open Command Prompt by following the first step again. 
  2. Now type the command mentioned below in the elevated Command Prompt and hit Enter to execute it. 
DISM /online /Cleanup-Image / ScanHealth
Scan Health of Windows
  1. Next, execute the following command. 
DISM /Online /Cleanup-Image /RestoreHealth
Fix: DISM Error 87 on Windows 10
  1. Once done, restart your PC and check if doing so resolved the issue. 

Hopefully, running SFC and DISM scans will resolve the error at hand on Windows 10. 

4. Enable Windows Installer Service. 

If you aren’t able to install any pending downloads on your PC, then there is a possibility that the Windows Installer service on your operating system is disabled. 

This service is designed to manipulate all the pending updates on your PC and if due to any reason it stops working, you will not be able to install the updates. 

The easiest solution to this issue is to check if the Windows Installer service is disabled and if it happens to be, enable it. 

Here is how you can do that:

  1. Press Windows + R keys simultaneously to open a Run dialogue box. 
  2. Inside the text field of the dialogue box, type ‘services.msc‘ and hit Enter. Doing so will take you to the Services window. 
  1. Inside the Services window, locate Windows Installer and right-click on it. 
  2. Select Properties from the list of options available and go to the General tab.
  1. Under Service status, hit the Start button and click on Apply.

  1. Finally, restart your PC. 

In case the Windows Installer service was disabled, enabling it will resolve the issue. If you want to disable this service in the future, simply follow the steps above again and click on Stop in the 5th step.

5. Reset Winsock. 

The Windows 10 update error 0x800705B3 can also be caused by network inconsistencies within the operating system. 

Sometimes, the entries in the Winsock catalog become corrupt or are incorrect. This can result in various issues, including the one under discussion. You can resolve the issue by resetting Winsock, as doing so will revert it to its initial, error-free state. 

Here is how you can do that:

  1. Type cmd in the search bar and click on Run as administrator to launch elevated Command Prompt.
  2. Inside the Command Prompt window, type the commands mentioned below one by one and hit Enter after each to execute them.
nbtstat -R
nbtstat -RR
netsh int reset all
netsh int ip reset
netsh winsock reset
  1. Once all the commands are executed, restart your PC. 

You should now be able to install the pending updates without any issues.

6. Try Using CleanMyPC.

Another easy way to get rid of the corruption errors within the system is by eliminating the junk, unwanted files that are no longer of any use.

It is common for these junk files to get corrupt over time, and cause serious issues within the PC. The easiest way of getting rid of them is by using an efficient PC cleaner that can handle all your PC-related problems, as it will save both your time and energy. CleanMyPC is the perfect tool for this purpose because it is a one-stop-shop for everything you need to maintain your system’s performance.

7. Reset Windows Update Components. 

If none of the methods mentioned above works for you, then we encourage you to go ahead and reset the Windows Update components on your operating system. 

As we mentioned earlier, Windows Update components can get corrupt and fail to perform required operations. The only way to fix bad components is to reset them, in case the troubleshooting utilities fail to eliminate the errors. 

Don’t worry, the method is not as complex as it sounds, and will not take much of your time. Worst-case scenario – if even resetting does not fix the issue at hand, then this implies that the issue is with your Windows and not its components. In this case, we suggest reinstalling Windows.

This brings us to the end of our guide on fix Windows 10 Update error 0x800705B3. We tried walking you through all the steps in detail and hope that one of the methods did the trick for you.
