How to uninstall Opera browser completely

  • How to uninstall Opera browser completely not through Add/Remove Programs?

    Could I do it manually by deleting Opera folder?

  • What Opera version, and is it installed as stand-alone or multi-user?

    Note that any application program that registers itself with Windows as a default program to open various file-types or links will leave pointers toward itself in the registry. Those would normally be removed by the application's uninstall mechanism which is invoked via Add/Remove Programs, but which would be left behind by a simple manual deletion process. Consequently, a manual deletion should always be followed by a careful use of a cleanup utility like CCleaner, etc.

  • When I use Add/Remove Programs feature, It notifies that the installation has been uninstalled.
    But, in reality, it has NOT been uninstalled.

    It happens after I upgrade to Opera 42 from Opera 41.

    My OS: Windows 7 SP1 x64, BTW.

  • Addendum: In Add/Remove Programs (or "Program Features" in Windows 7), it still shows as Opera 41 although I have upgraded my Opera to version 42.

    Now, the item has been removed after it can't detect Opera 42 installation.

  • But, in reality, it has NOT been uninstalled.

    What exactly makes you say that?

  • When I double-clicked the Opera 41 item (to uninstall it), it said that the installation of Opera 41 had been removed.

    But, in reality, the files (although they are Opera 42 files) still existed.

    Are there another ways to uninstall Opera 42? Via an executable maybe?

    Maybe because they are in the same folder?

    Try using Revo Uninstaller.
