>The point is, if Admin has rights to do anything, then malware will too.

Is my English not good enough? How do you control what you want to put on your C: drive if you do not have any rights at all? I cannot even copy a file into a new name. I cannot change the content of a simple text file to adjust for what I need. However, Task Manager allows me to start Windows Explorer in administrator mode. So, that results in the same. However, I cannot see what command it uses to do that. I went at the registry level and took ownership of the related key that did not change anything. The regular Windows Explorer icon went ok when I stopped the Windows Explorer.exe task from the Task Manager. That, of course, blank out anything. So, Ctrl+Alt+Delete to access Task Manager, restart Explorer.exe and then my icon allowed me to have full control on the C: drive. But, on the next reboot, it was reseted back to default. So, how I am suppose to do anything on that PC if my own account, which is an administrator account, cannot do anything on drive C:? This is a replica of my main PC for the road. So, how am I suppose to install anything on that PC if I cannot even get a hold of drive C:?
