 ### Agent Work Directories
 
 Starting from [Remoting 3.8](https://github.com/jenkinsci/remoting/blob/master/CHANGELOG.md#38) there is a support of Work directories, 
 which provides logging by default and change the JAR Caching behavior.

 ## Configurations
 
 The image has several supported configurations, which can be accessed via the following tags:
 
 * `latest`: Latest version with the newest remoting (based on `openjdk:8-jdk`)
 * `latest-jdk11`: Latest version with the newest remoting and Java 11 (based on `openjdk:11-jdk`)
 * `alpine`: Small image based on Alpine Linux (based on `openjdk:8-jdk-alpine`)
+* `latest-windows`: Latest version with the newest remoting (based on `openjdk:8-jdk-windowsservercore-1809`)
+* `latest-windows-jdk11`: Latest version with the newest remoting and Java 11 (based on `openjdk:11.0-jdk-windowsservercore-1809`)
 * `2.62`: This version bundles [Remoting 2.x](https://github.com/jenkinsci/remoting#remoting-2]), which is compatible with Jenkins servers running on Java 6 (`1.609.4` and below)
 * `2.62-alpine`: Small image with Remoting 2.x
 * `2.62-jdk11`: Versioned image for Java 11
 
 ## Java 11 Support
 
 Java 11 support is available in a preview mode.
-Only Debian-based images are provided right now.
+Only Debian-based images and Windows images are provided right now.
 (see [JENKINS-54487](https://issues.jenkins-ci.org/browse/JENKINS-54487)).
 There is a probability that images for Java 11 will be changed to AdoptOpenJDK
 before the final release of Java 11 support in Jenkins.
