It should be possible to remove the restriction -- though you'd "swisscheese' the security in Windows (i.e. poke holes into it -- and perhaps to the point where there won't be any security at all).

>Root is one of those protected locations that you need elevated admin rights to do things there. The file should be in a subdir under C:\Users\All Users or C:\Users\UserName

>>I have been asked to help fix a problem with a windows 10 upgrade. There is a .mem file in the root (c:\) directory that holds the local workstation path to a dot matrix printer on a network print server. This is read every time the program is opened. All was fine until W10 - now an access denied message from W10 pops up.
