I doubt it. I would suggest very carefully reviewing your script. I have not reviewed your script carefully, but the behavior you are describing seems like maybe your script is linking the font paths to ‘\hostnamec$pathfilename.file’ such that Windows locks those files when it boots, instead of linking the font files to a location in C:Windowsfonts. So SYSTEM is locking the files because Windows is using them for font reference instead of using font files in C:Windowsfonts.
