How can i remove the original games ( Jawbreakers and Solitaire ) from
my HP ipaq pocketpc (windows mobile 2003 Second Edition).

I am looking for a solution to permanently remove the games not just
to remove the shortcuts to the games via File Explorer.

Are these programs not part of the ROM?  If so you won't be getting
any extra memory if that is your goal.

Yes, these programs are part of the ROM. My objective is not to get
any extra memory, i just dont want to be able to play the addictive
jawbreaker.

Sorry for not giving you my full answer....I thought I had given you
another link....according to the manuals I looked at at HP for Ipaq (I
chose one at random since I didn't know your specific model)...the
software in ROM is not removable.

Thanks for the comment. I really would like to delete or permanently
block my access to those games. I even increased 5 times the price for
the solution.

You can't remove, but you can hide it:

Hope it useful for you

I would be very happy with any solution that would hide it and would
require a hard reset to bring it back.

Thanks for the suggestion but I did not understand how this "noextras"
would work in my case. I also increased the price to $100.
