elasticsearch - Deallocate Elastic Search Memory after uninstall

Question

I am on Windows 10 and I installed ElasticSearch from msi package and installed it as a service. I configured 2GB memory for its cluster and nodes while installing.

Now I want to uninstall it completely and deallocate all the memory, I uninstalled it from Add or Remove Programs and also made sure that I don't have any service named Elasticsearch in services.msc.

Even after uninstalling I see in my Task manager that 2GB ram is still being used and I believe its because of Elasticsearch.

How can I deallocate that memory? I have also tried restarting my computer multiple times but still 2GB memory is still allocated.

Answer 1

Task manager doesn't show usefull info, try to download https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer run it as administrator and discover dllhost.exe process - try to understand which dll is consuming resources.
