Microsoft has released today new Patch Tuesday updates for all supported versions of Windows 10, including the upcoming version 21H1 currently being tested by Windows Insiders in the Beta Channel. These latest updates are notable as they will remove the legacy Microsoft Edge browser from the OS, which is now unsupported starting today, and replace it with the new Chromium-based Edge if it’s not installed already.
If you’re a Windows Insider on the Beta channel, you can download the 21H1 build 19043.867 (KB5000802) today, which includes the same list of fixes as the builds 19042.867 and 19041.867 for Windows 10 versions 20H2 and 2004, respectively. Here are the key changes Microsoft detailed, in addition to the removal of the legacy Microsoft Edge browser:
- We fixed an elevation of privilege security vulnerability documented in CVE-2021-1640 related to print jobs submitted to “FILE:” ports. After installing Windows updates from March 9, 2021 and later, print jobs that are in a pending state before restarting the print spooler service or restarting the OS will remain in an error state. Manually delete the affected print jobs and resubmit them to the print queue when the print spooler service is online.
- Security updates to the Windows Shell, Windows Fundamentals, Windows Management, Windows Apps, Windows User Account Control (UAC), Windows Virtualization, Windows Kernel, the Microsoft Graphics Component, Internet Explorer, Microsoft Edge Legacy, and Windows Media.
New Patch Tuesday updates are also available for Windows 10 versions 1909 and older, which will also remove the legacy Microsoft Edge. The legacy Edge browser will no longer receive future security updates starting today, so it's really recommended to use another web browser if you don't install this month's Patch Tuesday update immediately.
