I have never liked the “Recent” tab in the SharePoint QuickStart navigation.
So here is a way to hide it forever! We do this by editing the properties of the link in the navigation settings of the site. We will display the link to all members of a newly created group. The thing is that there are no members in that group (other than the farm administrator of course).
Go into Site settings.
Open People and groups to create a new group
Switch the view to Groups
Click “New” to creat the new group.
Give the new group a name and enter a description.
Shouldn’t it say Group Description or something?
Leave all settings default and click “Create”.
Delete yourself from the group
If you created the group logged in with the system administrative account the group will be empty.
Go into Site settings and Navigation
And scroll down to Structural navigation
Select the Recent heading and click on “Edit”
Edit the properties for this Heading.
Find the newly created group by clicking on the address book.
Select “SharePoint Groups”
Search, select, add and hit “OK”
If all went well you should see this screen. Just click “OK”
And now the Recent heading will be hidden.
