I cannot delete a particular file Access Denied

I am tryiong to save, delete or overwrite the file "Clear Print Spooler.bat" in C;\windows\system32 and in each case get "ACCESS Denied" error. I have tried the above in the command window with admin. priviledge. Same error.

I had added a line that contained the word "Runas". Now I try to remove that line and save the file and get the error. On my other computer which the bat file has not been altered I can edit,save,copy move,delete and overwrite without the error. I think if I can edit the file to remove the extra line and then save it, I could remove the error.

What all have you tried so far? Will it let you change the file type to .txt ? How about making a 2nd bat file but give it the same name, (make it in a different folder) then copy it to where the bad one is? (win7 should try to overwrite the old with the new .bat file.

This problem was on another computer, so this is what I did using the suggestions you guys provided.
I change folder/file options so that the extension was available. and changed the extension to txt.
I then deleted the file.
On my computer I changed the extension to txt and copied the file to a flash drive. Changed the extension on my computer back to bat.
On the other computer I copied the file from the flash drive to the system32 folder.
I took ownership of the file and changed it back to bat.
I then made a shortcut and placed the shortcut on the desk top.Original problem solved.

One problem remains,
The shortcut I place on the desktop is in several non-administrative user accounts. When they use the shortcut to clear the print spooler they run it as the administrator and then have to use my password.
Understandingly, I am reluctant to give up my password. Anyway out of this?

The reason I need this is that I am maintaining this computer in an Assisted Living Facility and although I have several user accounts that are password protected I have one account for general use of any resident. The general use account is the one that piles up print jobs in the printer spooler. Apparently those users keep trying to print when the printer is off, out of paper or has some kind of error. Then another user comes along, corrects the printer problem and then tries to print a document. Because the spooler already has jobs ahead of them they must print multiple times before their print job is printed. Ergo,the clear spooler command.
