Nope... it is set to "S" (Misc issues)

Open the parent folder of some folder you've set an icon to, press the shift key and right click on an empty space of the window. You'll see, along with other commands, one that says "Open command prompt here". Click on it and you'll get a command window opened.

Then type:

attrib "<folder name>"

Hit enter and you'll see something like this:

S Drive:\Folder name

Example:

H:\Icomancer>attrib Icomancer
S H:\Icomancer\Icomancer

The "S" states for "System".

There is no way to set the "System" attribute to a folder from the Windows Explorer. You can only do it thru the Windows Shell API or thru the attrib command from the Command Line Interface (as shown above).
