title: run scheduled task with highest privileges
body: <p>Im am currently coding an application for auto updating ccleaner. Everything worked well until I enabled UAC.. I am using this project: <a href="http://www.codeproject.com/KB/cs/tsnewlib.aspx" rel="nofollow noreferrer">http://www.codeproject.com/KB/cs/tsnewlib.aspx</a>
  to schedule the updating process, but when uac is enabled I get every time a message if I would let ccleaner installer make changes to my computer. The auto updating process must be done silently without bugging the user with prompts of uac.</p>
  
  <p>When i manually check the "run with highest priviliges" box  in task scheduler it does run without a prompt. But I can't seem to do this programmatically. Or I havent found it yet.</p>
  
  <p>P.s. Sorry for the bad english</p>
