I am trying to update security updates for SP 2013. I tried to download one security update it has almost 52 items.How can I install these all items in one shot or quickly.Please suggest quickly.
You can get standalone package from this url: Download the security update KB4011653 for the 64-bit version of SharePoint Foundation 2013
After applying the patch, you have to run the SharePoint config wizard on all the SharePoint servers in the farm.
You can just download KB4011653 for SharePoint foundation 2013 from : https://support.microsoft.com/en-us/help/4011653/descriptionofthesecurityupdateforsharepointfoundation2013january9-2018
If you have multiple servers in this farm , you need to install the patches on all servers and run configuration wizard on each servers .
