I haven't seen this covered yet, so here's one more thing to look at
I wonder if you have the time to check the permissions that are set for your C:\Users and C:\Users\Admin folders ?
And then let us know how they are set.
Go to: C:\Users
Right click on it and select "Properties"
Left click on the "Security" tab, across the top
The following, are from one of my working machines
The windows that appears is divided into two sections
The top, lists the names of users and groups.
The bottom, lists the various permissions these users or groups hold with regard to access to the folder.
As you click on each user or group (on the top of the windows), their permissions for the C:\User folder are listed below.
What are the names of the users and groups that are on your machine that have access to the C:\Users folder ?
And, as you click on each of them, what are the specific permissions that they have ?
Please do the same for your C:\Users\Admin folder as well. (Your logged into Windows as “Admin” right ?
I’ll check them again a working machine here in my home and let you know if they look any different.
Thanks once again.
