I have looked all around the internet, and can't seem to figure out how to uninstall a WPI application. I accidentally installed something thinking it was something else, and now I can't uninstall it.

You could remove them via control panel. Depending on what you want to remove, you either need to: Go into windows programs and features and turn windows features on/off, locate the feature you wish to remove and untick it. Else Go to uninstall a program section and locate it that way and uninstall as you would any other program.

    Neither this nor the 'Uninstall or change a program' panel seem to have a list of WPI apps. Here's a good rundown: http://superuser.com/questions/482801/how-can-i-uninstall-a-component-that-was-installed-by-web-platform-installer – Paul d'Aoust Oct 21 '15 at 22:22
  • This was exactly what I needed to know and solved my issue. . – klewis Jan 24 '17 at 21:00
  • WPI components don't show up in Control Panel (at least none I've used) – MC9000 Aug 16 '21 at 05:29

I achieved this by opening IIS Manager selecting Handler Mappings (From the root node). I then deleted all PHP Handlers, I then opened FastCGI settings and deleted all php settings. I then removed all php entires from the system path and finally used those paths to know where PHP was installed and deleted the php folders. Finally The web platform installer allowed me to reinstall PHP and re-setup the handlers mappings for me.

You need to use Server Manager to do that.

  1. Start -> Control Panel -> Administrative Tools -> Server Manager
  2. Highlight Roles in tree view on left
  3. Under Web Server (IIS) section, look to right and click "Remove Role Services"
  4. Then uncheck the role you want to remove

This usually requires you to reboot the server after removal.

  • What operating system are you using? – tool4scs Jun 12 '13 at 18:40
  • I am not familiar with IIS on a consumer grade operating system, but maybe try installing IIS Management Console (Control Panel -> Programs and Features -> Turn Windows features on or off; expand IIS -> Web Management Tools). – tool4scs Jun 13 '13 at 02:01
  • Well what did it install, maybe it isn't called Server Manager and whatever it installed provides that same functionality. – tool4scs Jun 13 '13 at 18:51
  • For Windows7 (Professional) it is Computer Management, but there is no roles. The IIS is under Services and Application but since there are no roles I think we can't uninstall the WebPI application on this way. I am looking for the same thing. – manou May 08 '15 at 12:49
