can you right click any of the locked file and go to properties, there you may find any unlock button.I already took ownership of it but it didn't help.
Screenshot is attached.
i don't really understand your solution, can you be a little moer specific on how you fixed it? cause i have the same problemAfter taking ownership I set permissions for the whole drive and check to inherit that behaviour to all other folders.
That however was wrong.
I checked off the inherited permission, deleted it and added a new one (everyone, full access) to every folder in the root and now the security-locks are gone.
Thanks for your help though.
