Don't know why it's set to check every 13 min, but it checks Dell sites for updates to drivers, software, etc. and for problems with your system. Ron
Dell Studio XPS W7 SP1.  I had a bunch of tasks that came up with damaged images.  I've managed to repair most all fairly easy.  The oddball is/was SystemToolsDailyTest, a PCDr or pcrdcui.exe file.  The default schedule for it is to run every 13 minutes for 93 days!  Anybody know what it does and why anything needs to run every 13 minutes?  I know that I can change the time. Can anyone that has still has the OEM install of Windows, where their SystemToolsDailyTest file is located on their machine?  On my machine it was the only task not located inside a folder.  All others were in folders.  I had to take ownership of the folders and files, delete them, create a new folder and import the task from a backup created earlier.  I ended up creating a new folder for SystemToolsDailyTest because it errored when I tried to import it into the root stating that it or the folder already exsisted.  I wasn't about to delete and recreate the whole Task folder!
