[Solved] Delete all Duplicate records in a Table in SQL Server

I have table Example, that contain column name ID, OrgName, Address, WS

ID OrgName Address   WS   
1   ABC          sa            a         
2   TATA        ss            b       
3   MRF          dsds        c          
4   MRF          abfd         d         
5   TVS           ggg         e   

Now i want to delete those row which contain duplicate OrgName, Means i want to check only OrgName Column and not whole row.

I want this table like this

ID OrgName Address   WS   
1   ABC          sa            a         
2   TATA        ss            b       
3   MRF          dsds        c                 
5   TVS           ggg         e
