I just upgraded to Windows 10 and all went well except that it changed a folder with 20 or so Rhino models and made each file and each graphic associated with it locked. There is a lock icon in the corner of each file. I can’t double click to open the graphic files but the Rhino files open. I looked through the properties and all looks good. Does anyone know how these are locked? 
I just did a search online and it seems like you need to change permissions. Here is a link that may be of some help.
All my best … Danny
