Answer 1

Try running it from a normal Windows Command Prompt

D:\temp>"c:\Program Files\Android\Android Studio\jre\bin\keytool.exe" -help
Key and Certificate Management Tool

Commands:

 -certreq            Generates a certificate request
 -changealias        Changes an entry's alias
 -delete             Deletes an entry
 -exportcert         Exports certificate
...

Also, on Windows, you can't use ~/. Change that to a Windows style path like C:\Users\Norbert\keys, or wherever you want to keep the keystore.
