Need to delete data and Indexes from ES older than 7 days

Elastic Stack Elasticsearch
1

I have many indexes and the size of all those is around 10 GB. The data is around more than 2 weeks older. I need to keep data only for last 7 days.

As per my analysis, one way is to use
DELETE - http://myserver:9200/filebeat-2016.03.25
DELETE - http://myserver:9200/filebeat-2016.02.25
DELETE - http://myserver:9200/filebeat-2016.01.25, etc.

Other is to use CURATOR. Couldn't find anything for windows here. i.e. How to install, command lines, etc.

Can anyone let me know which one should I use and how to implement it using best practices ?

Curator does work in Windows. The rest of the documentation is available at https://www.elastic.co/guide/en/elasticsearch/client/curator/current/index.html
