I have applied the GPO user setting "Turn off the caching of thumbnails in hidden thumbs.db files" to every device on my network. It has been applied for weeks.
When I attempt to delete a folder on another server, that I have full access to and could otherwise delete with no issue, probably 50% of the time I will receive the "The action can't be completed because the file is open in Windows Explorer" message for the thumbds.db.
Every thread (of the hundreds about this clear 100% bug) says to enable the policy I have to fix this. I have, I've confirmed via gpresult /h and checked the registry key it creates under the user profile. I have no idea how a user policy is meant to stop what I think is the server creating or locking these files, or how with the GPO applied anything should be accessing the thumbs.db.
I am unsure what steps I can take now to ensure 100% of the time I can delete a network folder. This is such a simple thing I want to do and is stressing me to no end not being able to fix such a simple thing.
See below. This is from a server where I am trying to delete a folder located on another server. Notice the registry setting is set where it shouldn't be generating (and therefore I assume in anyway locking or accessing) the thumbs.db. I have confirmed and every other client that might touch this folder definitely has this same registry key set.
