 To fetch keys of builders and active developers, feed the list of fingerprints
 of the primary keys into gpg:
 
+On \*NIX:
 ```sh
 while read fingerprint keyholder_name; do gpg --keyserver hkps://keys.openpgp.org --recv-keys ${fingerprint}; done < ./keys.txt
 ```
 
+On Windows (requires Gpg4win >= 4.0.0):
+```
+FOR /F "tokens=1" %i IN (keys.txt) DO gpg --keyserver hkps://keys.openpgp.org --recv-keys %i
+```
+
 Add your key to the list if you provided Guix attestations for two major or
 minor releases of Dash Core.
