Question: where are gpg keys stored windows?
Answer: GnuPG for Windows 7 stores all its key files in %USERPROFILE%\AppData\Roaming\gnupg, but I wanted to change this path, say to D:\Profile\GPG, so that the files can easily be backed up. It turns out, there are quite a few different methods to change the path: changing the default keyring location in windows.
