the problem is i was in a specific version windows 10 and i play Games without problems or drop FPS or high usage performance and memory usage . with good performance. good FPS . PC fast. but when i update my computer to this lastest november version 2019 . pc become slow because the new versions of windows kill the old systems and needs to have more upgraded hardware ... xD

so i gonna reinstall the windows but i don't know whats the version should i install the right version that confirm my system hardware without any high performance usage that needs more and more ram at least 16. i want a version that use under 1 gega ram and performance. the most less version usage ram in windows 10 . is windows10 ( 2015 first version ) ? or 2016 version ? or 2017 version ?

hope you advice me the right version and build.
