[Gpg4win-users-en] dirmngr, for paranoids.

Hello, what operations this service do exactly, does it only cache requests or does it need to touch files somewhere? (Not including its own folder)
If It doesn't need to write files somewhere, or read files from user's personal file, we could start making it run with its own user too, by default. (Using NT SERVICE\DirMngr, automatically created by the system when dirmngr is registered as a service) for security's sake (as it won't be able to take down the machine if a flaw is found, since it won't run on an above-administrator account)

If it needs to write files somewhere (temporary files for example) it could use its personal folder (since it will run as its own, it will have one created by the system in, by default, %systemdrive%:\Users\DirMngr)

>From what I understand its purpose is to check revocated certs, does it store the revocations somewhere locally? (Probably) Where?

Not sure what you mean, dimngr gets started as a service running under the user dirmngr on debian if you have it installed.

1. Right click on Computer icon on your desktop or on computer in the startmenu.
2. Click on Manage
3. There is an entry Services and Applications.
4. Find dirmngr in the list and disable it.

Uaaah, we just love it when some Protection tools interfere with the Software
But yes as long as you do not use S/MIME at all you can pretty much do what you like with poor old dirmngr (Honestly I am not sure if you could not just delete it I have never checked what happens then)
