Uninstalling WebSphere Portal

To  uninstall WebSphere portal , start uninstallation wizard by clicking on "C:\IBM\WebSphere\PortalServer\uninstall\uninstall.bat"

Click on "uninstall.bat" (Run as Administrator if it windows)

Got warning saying , I may need to remove the WAS server manually

I have deleted leftover directory "C:/IBM/Websphere" from the uninstallation to clean up (make sure you are deleting only websphere portal server directory not any other shared install folder like "SDPShared ..etc if any)
