Delay in data updates

Hello,
I installed Grafana and Prometheus on a Debian server, then installed windows_exporter on a client running Windows 10. The dashboard was displayed as follows:

To test, I copied some files to the C drive, but it took a while for the dashboard to update to show the change in free space on the C drive. The prometheus.yml file looks like this:

# Sample config for Prometheus.

global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
      monitor: 'example'

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets: ['localhost:9093']

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # Override the global default and scrape targets from this job every 5 seconds.
    scrape_interval: 5s
    scrape_timeout: 5s

  - job_name: "Local_Linux"
    scrape_interval: 10s
    static_configs:
      - targets: ["localhost:9100"]

  - job_name: "Windows_10"
    scrape_interval: 10s
    static_configs:
      - targets: ["192.168.1.3:9182"]




    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

#    static_configs:
#      - targets: ['localhost:9090']

Where is my configuration wrong?

Thank you.
