Clear the TEMP folder on shutdown

I am following some instructions in More Ways To Speed Up Windows XP to help speed up my computer. One of those was to delete the temp folder on shutdown. Yet after I shutdown and then boot up, the script did not touch my temp folder, and I am unsure what's wrong. What should I change?

Here are the instructions I have:

1. Open Notepad and create a new file with the following entries:

RD /S /q “C:\Documents and Settings\"UserName without quotes”\Local Settings\
          History”
RD /S /q “C:\Documents and Settings\Default User\Local Settings\History”
RD /S /q “D:\Temp” <–”Deletes temp folder, type in the location of your temp 
                      folder”

2. Save the new file as anything you like, but it has to be a ‘.bat’ file,
   for example, `fastboot.bat` or `deltemp.bat`

3. Click ‘Start’ then ‘Run’

4. Type in ‘gpedit.msc’ and hit ‘OK’

5. Click on ‘Computer Configuration’ then ‘Windows Settings’

6. Double-click on ‘Scripts’ and then on ‘Shutdown’

7. Click ‘Add’ and find the batch file that you created and then press ‘OK’

I have followed these instructions, and I see where Windows says "Running Shutdown Script". Am I missing something here?

Rather than going through all this, which may be overkill to do it on a daily basis anyway, run something like CCleaner every week or so to get rid of the temp files.

It should be noted here somewhere, that if you ever go to install a program and the program installation fails, that you should disable wiping out the temporary folders at shutdown or startup.

I have been there and done that :-) Very rarely, a program will bust itself out in the temp folders, then reboot the system to complete the instalation. Ahh, you know the rest.
