How to fix "Realtek Semiconductor Corp - Extension" keeps showing up in Windows?

Issue: I have a problem with Windows updates, or rather – driver updates. Whenever I check the Windows updates section, it says Realtek Semiconductor Corp – Extension Driver update has been installed. Every time I initiate this process, I receive the same message that the driver has been installed. However, if I check the Reliability Monitor, I see numerous messages with the “Failed Windows Update” notification. This is pretty annoying, and I wonder if this could be solved. I really appreciate any help you can provide.

Solved Answer

Windows updates are regular occurrences that all users with Windows systems are accustomed to. Microsoft usually ships updates every second Tuesday of every month and can include all types of improvements. This process is often referred to as “Patch Tuesday” and can include all sorts of updates, including security, feature, quality, and more.

Drivers are particularly important to any Windows operating system, as they allow hardware and software to communicate properly, allowing users to achieve the maximum potential of their machines. Once installed, drivers can serve for a long time before they need to be updated, although this highly depends on the system component and what the users are using their computers for. That being said, it is recommended to update drivers whenever possible.

In order to provide users with as much convenience as possible, Windows also offer driver updates, although they are shown as optional, so users have to install them intentionally. Realtek drivers are among the most common sound (and other) drivers that can be offered for users, and those who have trouble with sound should make sure that their drivers are up to date.

Many users have reported that whenever they tried to install Realtek Semiconductor Corp – Extension Driver, the process failed, usually with errors such as 0x80070103. In other cases, people said that the installation process was completed successfully, only for them to see it being repeated over and over again. In this case, the warning about failed Windows update was also reported. The driver version, such as 6.0.9366.1 or 6.0.9369.1, is also present in the message.
