Here is how to check whether standard or enterprise edition is installed in SharePoint 2013.
Go to Central Admin >> Upgrade and Migration >> Click on “Enable Enterprise Features”.
This procedure stays the same to check standard or enterprise SharePoint 2010 and SharePoint 2007:
- When the “Enterprise” is selected and grayed-out, it’s an Enterprise edition of SharePoint!
- Here is the Standard edition screen: If, Standard option is enabled, then we can determine it’s a Standard edition.
