Recently, my company started working with a company where they wanted to redirect from an internal Intranet Kiosk site to a publicly available application site. The site apparently (due to lack of something) does NOT have the ability to remove any File Upload links when coming from the Kiosk URL. The Kiosk computers are running Windows 7 Pro with various GPOs and registry keys locking them down to using Internet Explorer in Kiosk mode replacing the explorer.exe on the user account. The problem is we have not been able to find a way to Disable "Choose File to Upload" dialogs in Internet Explorer 11. This seems like it should be a pretty straight forward option as you can disable File Downloads using GPOs but apparently disabling File Uploads isn't something commonly done.
A number of blocks are in place, but there is always the fun the user could have of uploading files by using their Environmental Variables (Example: %WINDIR%\win.ini) that we would like to avoid. In fact, I'd like to avoid any dialog to avoid any issues with seeing Libraries or Desktop folder paths.
Given Kiosk Mode for Internet Explorer has been an age old feature, I'm amazed disabling "File Upload" isn't some default option when you set in Kiosk Mode.
Please assist! Thanks!
