In July 2021, Microsoft will uninstall Adobe Flash Player from Windows 10, as well as some older operating systems, through the KB4577586 “Update for Removal of Adobe Flash Player.”
In July 2021, the latest update will become mandatory, marking the start of the rollout of Windows 10 version 21H1, which is scheduled to begin this month.
The KB4577586 update will be available in July 2021 as part of the Latest Cumulative Update for Windows 10, versions 1607 and 1507, as well as the Monthly Rollup and Security Only Update for Windows 8.1, Windows Server 2012, and Windows Embedded 8 Standard.
Microsoft will remove the Flash component from Windows through the KB4577586 “Update for Removal of Adobe Flash Player”. In June, the update will be included in the Preview Update for Windows 10, version 1809 and above platforms. “It will also be included in every subsequent Latest Cumulative Update” Microsoft said
In 2017, Adobe announced that Flash Player will be retired. Mozilla was the last browser company to announce the end of support for Adobe Flash in January, with Firefox version 85.0 becoming the final update to do so.
After the KB4577586 update was released, Microsoft Edge and Internet Explorer stopped supporting it. The arrival of open standards, as well as a failure to address certain serious security vulnerabilities, were factors in its demise.
