Currently, I am working on deploying LAPS to our environment. All servers are done but workstations are more complicated because of the different policy during the time which were applied to them.
Some of them have enabled default administrator some of them have disabled and added non-standard local administrator account.
Then to standardize it we decided to re-enable to all default administrators.
I decided to use the GPO.
You can find this option in
Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> Accounts: Administrator Account status
I hope that this helps you guys.
Have a good one.
