After you search for *.pwl you should get a list of obscure files with a .pwl extension. Single click to highlight them and hit delete or right click them and chose delete. Windows will ask for your confirmation to delete them. You know the kind of thing I mean, are you really, really sure, etc. Delete them all. Run a second search for the same thing and see if anything comes up. If not, reboot your 'puter and you should be able to view your document. If you continue to get a single .pwl file on each search, then it is self restoring, something I've rarely seen. If that's the case, you will have to rely on a better cracker program. I've got a cracker program on my hard drive that you will have to expand and run from a floppy and it will reveal all your passwords. Email me if you need it.
It's not the sort of program I profesionally can recommend, but you can have it for "evaluation" purposes.
It's a guaranteed Windows breaker
