This is the command:
explorer shell:::{05d7b0f4-2121-4eff-bf6b-ed3f69b894d9}\SystemIcons
It keeps failing, but after some troubleshooting and investigation I managed to know the cause of the problem: I run TC using admin rights, but this command seems to work only if I run it without admin rights.
So, is there a way to run a command with no admin rights from a TC that is using admin rights?
I've tried to use a BAT file including a command to decrease rights: runas /trustlevel:0x20000 and then the command I need to run, but it also fails

Any clue about this?
Thanks!
