How to fix Windows update error code 0x80070026?

Hello. When I try to install Windows Updates, I get an error code 0x80070026. This has been happening for a couple of months now. Is there anything that can be done to fix this?

Windows Update errors strike users regularly, and 0x80070026 is no exception. The problem has been around for years, although users are still trying to find fixes to this day.

While older OS versions had to be updated manually, Windows 10 has a built-in Windows Update feature, which detects, downloads, and installs the latest updates automatically. However, sometimes the device user may want to accelerate the installation of updates and launch the Windows Update service manually.

This is when an error may be encountered, which reads:

There were problems installing some updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help:
(The Name of the Update) – Error 0x80070026

As evident, there is not much information that the error message provides, except that there were some "problems" while trying to install the update. The error may be a result of many different issues, for example, corrupted system files or Windows update services. Therefore, there is not a universal way to fix 0x80070026 error.

Nevertheless, the system fails to install updates when one of the Windows Update Components fails to work properly. If resetting Windows Update Components does not help, we would recommend disabling your anti-virus temporarily, run Windows Update Troubleshooter, or check the system for malware.
