I really like the dbatools project. This is a series of PowerShell cmdlets that are built by the community and incredibly useful for migrations between SQL Servers, but also for various administrative actions. I have a short series on these items.
One of the cmdlets is Dba-OptimizeForadHoc, which is designed to help you determine if this particular setting is enabled on your servers. There are plenty of ways you could get this data from sp_configure or PoSh, but this is a setting you might want to check in a hurry when there are potential performance issues.
The cmdlet is easy to use and takes a –SqlServer parameter where you can list multiple instances. There are options for credentials that can be used for a connection, just remember that this credential needs to have rights to read the setting.
If this cmdlet isn’t useful, check out the full list. I bet you find some that you will want to try out.
