On Windows, the command prompt doesn't support single quotes, use " and escape the inner ones with \".

curl -H "Content-Type: application/json" -XGET "http://localhost:9200/logstash-pc-(2018-05-09)/_search?pretty" -d "{\"query\":{\"match\":{\"MSG\":\"Test3\"}}}"

I'd also suggest using Kibana dev console which makes all that easier.
