Not to mention that they have been one of the worst spammers 
on Usenet, off and on, and don't mind indulging in a 
variety of slimeball tactics like slandering their critics.

If you want an /efficient/ version of EE, check this:

Not a problem.  Eraser has a "task list" function for automating

routine clean-up chores around the hard drive, and comes with 
a DOS application, eraserd.exe, that happily accepts commands 
from DOS batch.  Unlike EE and EEE, it's GPL.

How much to wipe depends on your threat model.  EE was 
designed with neurotic fear in mind, and that's the basis of
their whole sales pitch.  Most any /practical/ threat model is
very adequately addressed by using Scramdisk or similar to 
confine data & applications to an encrypted container or 
partition. To spot data leaks from applications (such as the
temporary files written & wiped by the GPGtray front end), use 
filemon.exe from -- lotsa fun free 
toys there.

If you need to wipe (not just delete) registry keys, I only
know of one way to do it:  Have autoexec.bat wipe your entire
system.dat & user.dat files on start-up, and replace them from
known clean backups. (Remember to update the backups when 
you install or remove applications!)

Nah, it's not that bad.  It usually takes Eraser about 10 
seconds to eat everything on my hit list, and I do tend to 
be paranoid.  Well, this is wandering off topic for the list, 
so I'll quit on the subject.  Anyone who wants to see my 
slightly outdated nonsense on how to realistically clean up 
a Windows 9.x box, can go to
