14 DAY TRIAL // The most recent cumulative update for Windows 10 May 2019 Update, or version 1903, also includes a fix for a DPC latency spike issue, according to Microsoft itself.
While the changelog does not reveal such an improvement, Pete Brown, member of the Windows PAX team at Microsoft, said on Twitter that this latest cumulative update refines the audio performance on Windows 10 by resolving the latency error.
“The Windows 10 1903 DPC latency spike issue (causing audio glitches on some PCs) is fixed in KB4505903. You should see that come through Windows Update normally, shortly. If in a hurry, you can grab the stand-alone installer,” he said, pointing users to the Microsoft Update Catalog page to download the cumulative update.
Windows 10 cumulative update KB4505903 increases the OS build number to 18362.267 on devices where Windows 10 May 2019 Update installed.
It can be downloaded from Windows Update with a manual check for updates or from the Microsoft Update Catalog page linked above.
Microsoft Edge changes
KB4505903 is also believed to be testing a new behavior that Microsoft could use in the future on all Windows 10 devices to replace the existing Microsoft Edge browser.
Microsoft is moving Edge browser to the Chromium engine, and testing versions are already available for download on Windows 7, 8.1, 10, and macOS. After installing this cumulative update on a Windows 10 device, the existing version of Microsoft Edge appears to be removed from the Start menu and the search results page, albeit it continues to be available on the system.
This change, however, isn’t yet enabled for all users on Windows 10, but only for a limited set, most likely as Microsoft is still experimenting with this idea.
The new browser doesn’t have an ETA just yet, but it could replace the current version of Microsoft Edge in Windows 10 as the new default in the spring of 2020.
