Disable / Remove share button, follow button and synchronize button Sharepoint 2013

In spite of deploying code or jquery scripts, I wanted to know if there was a way of disabling buttons in SharePoint itself..
So I found out that you don't need any code/script to disable those buttons (share, follow and synchronize).

Here's how:

• Disable "Share button" 

1. Go to Site Permissions
2. Select Access Request Settings
3. Unmark Allow access request

Remember: You have to do for each Site and Button will still be visible for Admins

• Disable "Follow button"

1. Go to Site Features
2. Deactivated Following Content Feature

Remember: You have to do for each Site

• Disable "Synchronize button"

1. Go to library settings
2. Go to Advanced settings
3. Say No to Offline Client Availability

Remember: You have to do for each Library

All done :)
