[Ham-Computers] Win XP batch files?

[KD7JYK DM09]

There MUST be a trick...

>From what I've read on the web, XP doesn't use batch files during startup 
and there's no one particular file it even starts from like older version of 
Windows...

Here's my problem.

Some cookies get a death grip on my computer.  None of the various standard 
methods of deleteing cookies and clearing files removes them.  Even trying 
to lock out ALL cokies doesn't work as many websites just bypass security 
measures and dump them to the drive anyway.  Using a different browser 
didnt' work, no accept, no function.

I have to restart into safe mode, sign on as an admin, go to my default user 
account, browse the hard drive and delete the files...  THEN, restart again 
in regular mode, as opposed to safe mode, and hope it took, which seems to 
be about 75% of the time, go figure.

Is there a trick to running a batch file or command line during startup in 
XP before a user account is assigned?  All I want is to go to a directory, 
run del *.*, then back out.

Any ideas or routes of research appreciated.
