Microsoft releases regular security patches for Windows 10/11 in the form of Windows Updates. These updates are designed to address bugs, improve performance, introduce new features, and boost security of the operating system. To keep your PC functioning at an optimal state, you need to install these system updates when they become available.
Windows Update is an essential service that automatically downloads and installs security updates on Windows computers. Unfortunately, there are times when issues come with these updates. It even reaches a point where Windows users cannot install them. One common Windows Update issue is the Windows Update 0x8900002A error in Windows 10/11.
What Is 0x8900002A Error in Windows 10/11?
0x8900002A error is a Windows 10/11 issue related to a faulty update or a system issue. It is possible that there are some bugs or issues with the update that needs to be installed in the Windows system. If this is the case, updating or rolling back the latest update should help.
When 0x8900002A error error message pops up, it shows nothing but a code or the issue indication. Users are not able to understand what the problem is when they only see the notification on the screen. The error message only states:
Pro Tip: Run a dedicated PC optimization tool to get rid of incorrect settings, junk files, harmful apps, and security threats that can cause system issues or slow performance.
The operation requested is not supported by the hardware backing the volume. (0x8900002A)
It is possible that the drive has errors, preventing your computer from completing the update. It could also be due to system folders or files that got corrupted because of various reasons, including cyber infections, incorrect program installation, and compatibility issues. A quick and easy way to fix the 0x8900002A error in Windows is running a scan using Outbyte PC Repair, a PC optimizer that resolves common Windows error.
Such PC repair tools and similar optimization applications can indicate affected or damaged files in various machine parts like Windows registry and system files. If you recently changed things on the machine or installed applications before the error occurred – it might be the trigger for this problem. You should assess these facts, troubleshoot system issues, and then move on to methods listed if nothing gave needed results.
What Causes 0x8900002A Error in Windows 10/11?
The Windows Update error 0x8900002A can be caused by a wide range of factors, including:
- Windows Update glitch – This issue can occur due to a recurring WU problem. Under certain circumstances, the updating component will become stuck and unable to install any new pending update.
- Windows update service is stuck in a loop – This issue can also occur if one or more Windows services are either started or stopped.
- WU associated DLLs are not registered properly – Windows Update relies on dozens of Dynamic Link Library files when searching for and installing pending updates. If any of these files is missing, then WU won’t run properly.
- System File corruption –Windows Update is part of the system utilities. A single corrupted file can effectively break the whole WU component. Therefore, if some of its files are corrupt, the system is bound to show the error message. To fix this, the affected user must run an SFC scan through the Recovery Menu.
- Third-party AV is closing ports used by Windows Update –Third-party security tools can be so overprotective that they have a tendency of closing legitimate ports used by Windows Update.
- 3rd Party Conflict – This usually occurs when there is a third-party security software program that is blocking Windows Update from accessing MS servers. In other instances, it can be a generic driver that was replaced with an equivalent from a third-party. If that’s the scenario, you can solve the issue by using System Restore to take your computer back to a point when this issue wasn’t occurring.
Each of these factors requires a different approach to solving the issue. However, if you’re not sure of the actual factor responsible for the Windows Update Error Code 0x8900002A, you can apply these solutions chronologically.
