How to remove Adobe Flash from Windows 10

Adobe Flash is dead and it’s been dead for a while but you will still find traces of it on your system, in your browser, and on certain websites. This year marks the absolute end to all updates and bug fixes to Adobe Flash so it’s the perfect time to rid your system of it.

Since Adobe Flash is tricky to get rid of, Microsoft has released an update that will remove it from a Windows 10 system completely. This update isn’t available via Windows Updates, not even as an optional update.

Remove Adobe Flash from Windows 10

The Windows update that can remove Adobe Flash from Windows 10 can be downloaded from the Microsoft Update Catalog. 

Warning: This update, once installed CANNOT be uninstalled. The change is permanent. The only way to ‘undo’ it is to install Windows 10 fresh,

  1. Visit the Microsoft Update Catalog.
  2. In the search bar, enter KB4577586. This is the name of the update that will remove Adobe Flash.
  3. Look through the results and find the one for your system.

  1. Click the Download button for the update you want to download.
  2. In the new window that opens, click the link.
  3. Save the MSU file to your local disk.
  4. Once downloaded, run this file.
  5. Confirm that you want to install the update and remember that it cannot be rolled back.

Selecting the update to download

If you’re not sure which update to download, read the name/description of the update in the Title column and Products column.

  • The update must say Windows 10 in the Products column and NOT Windows server.
  • Select the correct update based on your system’s architecture i.e. 32-bit Windows users will download the x86 update while 64-bit Windows users will download the x64 update.
  • The update is available for all versions of Windows 10. Check the version number (1903, 1909, 2004) and download the correct one.
  • Users on the Windows 10 October 2020 will download the 2004 update.


This update will remove most Adobe Flash from the system however, it will still be present in Edge. The Flash item from the Control Panel will be removed. As for other traces of it, they will still remain in browsers. Microsoft will likely release another update either for Edge or for Windows 10.

Many browsers may have their setting/option for removing Flash. Check online for when it will be deprecated for your browser or how you can remove it manually. You may not be able to remove a small subset f websites after this but Flash, at this point, isn’t secure and you’re better off not visiting websites that still use it.
