Tracked as CVE-2021-34484, the “zero-day” flaw enables hackers to breach all versions of Windows (including Windows 10, Windows 11, and Windows Server 2022) and take control of your computer.
Microsoft mistakenly thought it had patched the vulnerability (which was first found in August) when it was publicly disclosed in October. But the fix itself was found to be flawed, something the company admitted, and this drew even more attention to the vulnerability. Microsoft subsequently promised to “take appropriate action to keep customers protected” but two weeks later, a new fix has still not arrived.
Luckily the third-party security specialist 0patch has beaten Microsoft to the punch with a ‘micropatch that it has now made available for all Windows users “Micropatches for this vulnerability will be free until Microsoft has issued an official fix," 0patch confirmed.
You will need to register for a 0patch account and install its download agent before the fix can be applied, but with 0patch fast becoming a go-to destination for hot fixes which beat software companies to the punch this is a no brainer. Hopes will be high that Microsoft can release an effective patch sooner rather than later but, until then, all Windows users must act now if they want to be safe.

Error CausesError code 80070103 affects Windows users who attempt to access the latest updates for hardware drivers using Windows Update. Windows 10 users who are affected by this error code will be unable to complete the upgrade process. This error code usually occurs due to the Windows Update attempts to download an incompatible version of a driver or a driver that is already downloaded on one’s device.
Error CausesThe cause of error code 80070103 in Windows 10 is usually easy to determine. This is due to the fact that the error code only affects users who attempt to access updates related to hardware drivers. In such cases, the error code will only occur if the Windows Update website or tool on your machine attempts to install a driver that is already present on one’s machine or the version of the driver is unsuitable for one’s machine due to lower compatibility.
Manual repair methods are very effective in helping Windows users fix problems related to error code 80070103 as well as other errors. These repair methods can usually be implemented by users with very limited technical skills. In some cases, however, you may need to contact a Windows repair technician, i.e. if you have problems following the manual repair method instructions provided or if the repair methods prove unsuccessful.
In the case of error code 80070103, the problem can be rectified by either hiding the update or reinstalling the hardware driver. Windows users can hide an update on the Windows Update website or via Windows Update within their machine’s Settings. However, users will need to contact their device manufacturer to reinstall hardware drivers in most instances. See below for further details regarding these manual repair methods.
In the case where you are informed via an error message box that a driver, for instance, your graphics driver, is incompatible you may need to consider hiding the update to prevent error code 80070103 from reoccurring on your machine.
The incompatible issues will come about when the Windows Update website attempts to download a driver that is already on the device or one with a lower compatibility. When you hide the update, it is in essence, preventing Windows Update from offering this driver in the future. To complete this manual repair method, follow the steps below:
You may also complete this process by opening Windows Update within your computer’s settings, then selecting the Optional update or available link. Once you’ve done this, you may then select the updates you would like to install and hide the update that has resulted in the occurrence of error code 80070103.
In the case where you need to install a hardware driver, you will need to contact the manufacturer of your device. Once you’ve contacted the manufacturer or visit the manufacturer’s official website, you can then install the latest device drivers manually. Read the instructions for the installation of the latest drivers carefully. This will ensure you avoid any problems and improve your chances of successfully fixing error code 80070103.
After you’ve contacted your device manufacturer and completed the process of reinstalling the hardware driver, check Windows Update to see whether or not error code 80070103 has been rectified. If the problem was related to your hardware driver and you successfully reinstalled the driver, the error code will not reoccur when you attempt to download the latest updates for your hardware drivers.
However, you may need to take another approach if this manual repair method fails to fix error code 80070103. For instance, consider getting help from a Windows repair technician who is equipped with the skills and expertise necessary to offer a detailed inspection of your machine. Though the error code is related to one’s drivers, the fact that a Windows error code occurred may mean that your system needs a thorough evaluation as other issues may be present.
