Hey, I have an issue with the Windows 10 update. It fails for me. It is happening for a while and I would like to fix it as soon as possible. I get this Windows update error and the code 0x800705B3 presented when the problem occurs. I tried a few times to wait and launch it again. As the window said. No luck. Help!

Windows update error 0x800705B3 is occurring while the user tries to install the latest operating system upgrade. The pending update remains uninstalled the problem is not changing after some time. Users encounter a particular error for quite some time now. The issue can be related to particular driver issues, so the installation of updates cannot happen when those provided driver updates are not properly installed due to the existing issue.

The problem can be related to particular integrated webcam driver updates and Bluetooth adapter driver updates. There are different causes and each incident is unique with certain fixes. If the general inconsistency of the OS updates is responsible for the error, you might fix it with the update troubleshooter that indicates why the process is glitching. The common bug in the update itself leads to other system issues.

Sometimes disabled Windows installer service can lead to issues with the pending upgrade installation. The error code can occur when the process is failing every time. The Windows update error 0x800705B3 can occur too in such a scenario too. Enabling the service should easily solve the issue.

The most common triggers for various errors include system file corruption. When the particular piece of data is altered during the malware infection or due to the failure of other installation/ uninstallation, the error occurs when those files are needed. The particular file corruption affects system processes and built-in utilities. So the update error can also get triggered when the needed data is not accessible or stable enough to be launched.

You can solve these issues with system processes like SFC scan and repair those detected problems. However, there is a much easier way to check for and to solve system file corruption issues.
