It seems like AEM didn't stop properly.

Please open your command prompt and run below commmands

netstat -ano | findstr :4502

It will return you PID(note that down)

After that run the below command:

taskkill /PID <typeyourPIDhere> /F

Please refer this blog Windows Kill Process By PORT Number.



You can find the instance running in background/apps, by going to Task Manager (Ctrl + Shift + Esc) and there, if you find the AEM instance running in Apps as Java(TM) Platform SE binary, you can click on "End Task" after right-clicking on it.



you can find AEM process PID by using:

ps -ef | grep java | grep cq-quickstart

You might want to check services if AEM is started as a windows service. Check [1] for more details.

ProTip : If you need to manually kill the java process . ENSURE that AEM is not writing to disk or you risk data corruption.

So a quick way to do this is to check the segmentstore /crx-quickstart/repository/segmentstore and view the last modified timestamps on all the TAR files. Ensure that it hasn't written to disk in the last few minutes before you kill the process. Otherwise when you bring it back up you could have issues trying to mount the repository.
