To upgrading SharePoint server 2013 Enterprise from 15.0.4569.1000 to 15.0.4641.1000 had a long investigation and searching on web made me confusion. Even I didn’t find any clear way that to reach there. So I kept my finger crossed and jump into my another SP Farm which has the same build. Finally got a clue and spins a toss. What does it? Just keep down your’s eyes 🙂
After that we have to install the security update for SP server KB2880994 file.
Finally you will get an updated SharePoint server 2013 enterprise with Build 15.0.4641.1000.
