I was running
Windows 7 Ultimate (version 6.1.7600) and for some problem I cannot resolve, I had to reinstall it (I cannot rely on
restore points). Now I've seen something that I didn't notice ever (neither in
7): standard users (non-admin users) can delete file/folder that they didn't create. To investigate this, I opened properties dialog box of a drive, choose security tab, and saw that there is a user group named
Authenticated Users, who have the privilege of modifying and writing to every drive. From there if I uncheck
modify checkbox for
Authenticated Users, then files cannot be deleted from non-admin user account.
Computer Management window, I choose
System Tools > Local Users & Groups > Groups from the left pane. The middle pane lists all groups but I didn't see
Authenticated Users group.
I'd like to give only read, list and execute permissions to users in
Authenticated User group. How can I do that? Thanks for your time.
