You can now download KB5027215 using the direct download links below or through Windows Update. This is a security update that also addresses a Windows kernel information disclosure vulnerability. However, it does not include any new features for the Windows 10 OS. That said, Windows 10 version 21H2 is reaching End of Service today, which means it will no longer receive Patch Tuesday updates. However, only Windows 10 Enterprise, Education, IoT Enterprise, and Enterprise multi-session editions will be supported. Moreover, Windows 10 version 20H2 reached the End of Service last month, so this update does not apply to it. Most of the improvements included in KB5027215 were released in last month’s optional non-security update KB5026435. So if you installed that update, then this one ought to be a small one. To learn more about the security vulnerability fixes with this update, refer to Microsoft’s MSRC vulnerability guide. In the Vulnerability Guide, set the filter to “Update Tuesday (2nd Tuesday of the month)” and then select “June 2023” in the “Vulnerabilities” tab.

Known Issues in KB5027215
An issue with the standalone (clean) installation of Windows 10 with this update is causing Microsoft Edge Legacy to be removed. However, it is not being replaced by the new Chromium-based Edge. This occurs only when Windows has a custom offline media or an ISO image installed that does not include the 29th March 2021 SSU update. Microsoft suggests that you either install the March SSU update through slipstreaming or simply update an existing OS through Windows Update, so you will not be facing this issue. Alternatively, you can simply download and install the new Microsoft Edge if you have already encountered this problem. This issue has been around for a while and Microsoft still hasn’t fixed it.

Windows 10 KB5027215 Hands On
Unlike KB5027231 for Windows 11, KB5027215 was a lot smoother to download and install. It did not get stuck and was relatively faster as well. The update got downloaded and installed in a total of less than 12 minutes. Note that the last month’s optional non-security update was not installed, which means that KB5027215 should include all previous updates and fixes as well. Another thing we noticed was the storage capacity before and after installing KB5027215. While the update was only downloaded and not installed, the storage capacity decreased by almost 1.1 GB in the C drive. However, once the update was installed, the total free storage space decreased by 1.6 GB! Moreover, when we went over to perform a cleanup of the old Windows files, there weren’t many. In fact, all we could clean up was a total of nearly 1 GB. After the cleanup, the total beginning and ending free storage capacity was decreased by nearly 0.7 GB. Apart from this observation, the rest of the features and UI remained the same. We did not encounter any issues while maneuvering around the Windows 10 OS.
