However, this isn’t your standard monthly cumulative update. Instead, it’s an update that Microsoft pushes from time to time (via WindowsLatest) to address problems that may prevent Windows Update from downloading and installing updates on your computer. According to the official page, the “update includes reliability improvements to Windows Update Service components in all editions of Windows 10, version 1507, 1511, 1607, 1703, 1709, 1803, 1809, 1903, 1909, 2004, 20H2, 21H1, and Windows 11 (original release).” Th update KB4023057 ships with components to resolve virtually any problem that may be affecting the update mechanism of Windows. It is rolling out automatically, and during the installation, it can reset the network settings, remove registry keys preventing updates from installing, repair corrupted components of Windows Update, compress files if the device is running low in space, and it’ll attempt to reset the Windows Update database, history, and repair problems that may be blocking updates from applying successfully. The Windows update KB4023057 is also available for download manually from the Microsoft Update Catalog website. However, if Windows Update is working as expected on Windows 11 or 10, applying this patch is unnecessary. All content on this site is provided with no warranties, express or implied.
