creating a vbs script

Hi I would like to have the following done on the computers on the LAN.

I want a vbs script that will run on a schedule that will clean the following folders.

%userprofile%\Local settings\temp\*.*
%userprofile%\;local settings\temporay internet files\*.*
%windir%\temp\*.*

I would like the script to clean all the unused files and skip the ones that are in use. One problem I have is that does it find the location of these folders with no problems because most of these are hidden folders or do we need to apply attrib switch to make sure the script will run and find the location with no issues. Also I want to know if this script will need to run using admin account.

Thanks for you help
