This worked but is not mentioned in the help (gpg -h) at all even
though it seems to be the most important command one needs in order to
use GPG... (hint, hint)

I tried installing gpg4win last week on my PC but had to uninstall it
afterwards because it invaded my Outlook 2003 to such an extent that
it became unusable for normal email use. :-(
So I had to revert to installing GPG instead and then I don't have any
integration with Outlook anymore so I have to start using Thunderbird
for encrypted correspondence (with Enigmail). Sigh....
Funnily I only found GPG 1.4.9 on the GnuPG site even though Gpg4Win
came with some version 2.0.x, why is this?
And might my problems with Gpg4Win stem from its use of a GPG ver 2
Several years ago I had installed a Gpg4Win on a PC, which integrated
OK with Outlook, not at all like the one I found last week.
I also seem to recall that back a few years there was a piece of
software that after installation offered a rightclick menu item in
Windows Explorer for encrypting/decrypting a file depending on the
file type clicked on. If it was an ASC file it offered decrypt and
But I have failed to find such software now. Maybe I am only dreaming
or possibly it was part of PGP7, which I used at one time?
