I am trying to update my Central Store with updated ADMX files but I am getting a message about files being locked/open and it prevents me from copying new files over the old versions. Please see attached. I definitely have done this 2 times in the past with no issues and I am not sure what the problem is at this moment. We are running a mix of 2012/2012R2 servers, with the PDC being a 2012. The ADMX files are for Win10 (1511) version. I am trying to copy/paste those onto the PDC server.
Please see the error below. Is there perhaps a service that I should stop before trying to update those?
