Windows builder snapshot 1809

A snapshot of the newer Windows builder image as of this writing (Windows Server Core 1809).

You can use it to find what is available and where to find it, in more concrete terms than what The Windows Build Environment - Travis CI says.

The snapshot is built with the following .travis.yml:

os: windows
language: shell

script:
    - |
      for key in hklm hkcu; do
        reg export $key $key.txt
        gzip $key.txt
      done
    - find /c | gzip >disk.txt.gz
    - set >env.txt
    - curl -T "{disk.txt.gz,hklm.txt.gz,hkcu.txt.gz,env.txt}" ftp://$FTP_USER:$FTP_PASSWD@$FTP_SERVER/

(then the resulting files are repackaged into a single archive)
