[JENKINS-43930] Windows Agent Service Installer may leak File descriptors #22053
Description
Windows Service installer for the Jenkins master uses the "Redirect.log" to retrieve the result of the service start command. If the read issue happens, the file descriptor may be leaked. In such case new service start attempts within Jenkins will be failing till the instance restart.
Same as JENKINS-42670, but for the module
