Description

Find where 'Everyone' and groups like 'Domain Users' are set throughout SharePoint.

Step-by-step guide

There are 2 ways you can do this:

Start the SharePoint Essentials Toolkit
Select the sites that you wish to include in the report
Right click and select "Create Reports→Check User Permissions"
Enter the name of the account such as 'Everyone'
Click "Run Report"
The Job will start and once it is complete you can view the report
You can sort and group by dragging column headers and then Click 'Save View' to save the layout, and you can click 'Export' to export the report to SharePoint or MS Excel.
You can sort and group as you would like to display the results

Repeat steps 1-3 above
Right click and select "Create Reports→Permissions"
You should see the screen below, Click Run Now
The Active Logs window will appear to show you progress
Once the report is complete, you will see the following screen
After opening one of these reports, you can click CTRL+F to open the search panel to find 'Everyone' or any other account you like.
You can also right click a report header and select 'Filter Editor' to filter where 'Display Name' = 'Everyone' for example
In this example, I filtered to find where 'Information Technology' is granted access. You can substitute this for 'Everyone' or any other account.
Below we found 2 sites that 'Information Technology' group has access.
We can also right click on the item to remove access using the SharePoint Essentials Toolkit
