Recommended Scheduled Tasks

I currently have several scheduled tasks, and I was wondering what my fellow geeks had. I'm mainly looking for computer optimization tasks that you are using, ie. defraging, scanning, etc.

 

It's not a scheduled task (although it could be easily), but this is what I use for basic maintenance:

Code:

@echo off
PATH %PATH%;"c:\program files\ccleaner\";"c:\program files\pagedefrag\"
ccleaner /auto
if exist "D:\CGL\My Logs\chkdsk-c.log" del "D:\CGL\My Logs\chkdsk-c.log"
chkdsk c: /c > "D:\CGL\My Logs\chkdsk-c.log"
chkdsk d: /x
defrag c:
defrag d:
pagedfrg -o
shutdown -s -t 60 -c "Maintenance Complete!"

Script assumes that I have CCleaner installed, and the PageDefrag executable in the c:\program files\pagedefrag\ directory.

When run, this will silently run ccleaner to blast temp files, run a chkdsk against my hard drives, read-only for the system drive, with a log written to the storage drive.

Then it defrags both drives, and schedules a defrag of my registry and pagefile. Then it shuts down the computer.
