The Windows 10 "Tuesday Patch" update will remove Flash Player completely in July

Microsoft is slowly removing FlashPlayer from all versions of Windows10. An optional update to remove the FlashPlayer has been available for download since February as part of a "phased" rollout approach that pushes it out to users at different times.

Consistent with last year's announcement, Microsoft has quietly confirmed that AdobeFlashPlayer will eventually disappear from every system with the mandatory security update "Patch Tuesday."
In 2020, Microsoft explained that FlashPlayer will be removed in stages. The company first ended support for AdobeFlashPlayer on its Web browsers (Edge and IE11).

In February this year, Microsoft released FlashPlayer KB4577586 patch "killer", as WindowsUpdate (WU) and WindowsServerUpdateServices (using WSUS) optional updates.

In our tests, we found that installing Windows10KB4577586 from Windows Supdate or WSUS permanently removed AdobeFlashPlayer from the system.

As you can see in the screenshot, this patch cannot be removed manually, but users can still restore the Flashplayer by using the earlier system restore point or the "Reset this computer" feature.

On April 27, Microsoft quietly updated its original announcement that the new changes would be available in June and July. Following the updated roadmap, a separate update is no longer required to remove the FlashPlayer.

The optional "C" and "D" updates for Windows10 will be released in June this year and will remove the FlashPlayer.
Version C or D of Windows10 Update comes out in the third or fourth week of each month. These updates are completely optional, they include most non-secure updates and will be pushed out along with the mandatory "Patch Tuesday" updates (internally known as "B" releases).

If you skip the optional update, the FlashPlayer will be officially removed with the Tuesday July patch update.
