Microsoft is once again rolling out Windows 10 KB4023057 to improve “Windows Update reliability” on older versions of the operating system, including the October 2018 Update. In other words, this update could prepare Windows 10 version 1903 upgrade for older versions of Windows 10.
As Microsoft explains, Windows 10 KB4023057 will apply a series of changes to prepare the devices for future updates. During the installation, the device could stay awake for a little while and the update may also reset network settings if problems are detected. Similarly, it will also clean up registry keys that intentionally or unintentionally block Windows Updates.
It can repair corrupted services, reset the Windows Update database or even compress files in the user profile directory.
KB4023057 is rolling out via Windows Update and it may not show up on all devices.
The same update was released earlier this year and it’s not clear what has changed since the previous release, but it’s likely that the purpose is to prepare devices for Windows 10 version 1903.
About the May 2019 Update
Microsoft released Windows 10 version 1903 (May 2019 Update) at the end of May 2019 and the update is gradually rolling out to compatible PCs. The May 2019 Update for Windows 10 has had its share of issues, including a bug that breaks down Windows Sandbox.
In May, Microsoft acknowledged a bug in May 2019 Update that may cause an intermittent loss of Wi-Fi connectivity on PCs with outdated Qualcomm WiFi drivers. Microsoft says it has blocked the upgrade from being offered on such devices until the updated driver is installed.
In a new update to the support document on August 1, Microsoft changed the bug status to ‘Mitigated External’. Microsoft has also posted a workaround that says affected users should download and install an updated WiFi driver from device manufacturer and then check for Windows 10 May 2019 Update.
“Before updating to Windows 10, version 1903, you will need to download and install an updated Wi-Fi driver from your device manufacturer (OEM),” the support document reads.
