I used the uninstaller for Flash to remove the mozilla firefox plugin successfully as far as the plugin goes. However, this appears to have left code on my windows 10 machine. Specifically the Windows control panel entry for Flash Player (32-bit) remains active. Arjun Singh at Adobe support wanted me to clean files off the C drive WHICH HE SUBSEQUENTLY RETRACTED (no harm in my case I deleted nothing). Glary Utilities reports about 100 files on the C drive containing the word Flash. A considerable number of those relating to companion products like printers and Adobe Acrobat Reader. The suggestion was then made to inquire here how to get the Flash Player (32-bit) Windows Control panel to be removed. My machine has multiple users all users have a .lnk entry to Flash Player (32-bit) in their AppData\Roaming\Microsoft\Windows\Recent directory.
Most likely it's because the Microsoft distributed version is still installed. It is by default on Windows 8.l and Windows 10.
You can remove it by installing this Microsoft update. Note that this update can't be easily undone. You can also wait until Microsoft removes it automatically later in 2021. It doesn't really matter as Flash playback will be blocked in a two weeks anyway.
Also: I would be careful with cleanup utilities or registry cleaners. If you delete the wrong files it can cause all sorts of problems.
This is a tempest in a teapot. Those files aren't harming anything. Just leave them. Let Microsoft remove them when they send out their updates later.
Ok my mistake, I thought this was from adobe.
