Sorry, im not english speaking, so i didnt want to be rough, just tell the truth.
I had it running with 4gb (2gb for VM) it was working "fine", even some plugins. So this must be on your end. - I just had to auto restart all dockers every day because of some random dockers filling up ram.
Anyway, RAM prices are cheap, and it cost around 1-2 watt per stick, so usually doubling ram dont cost anything.
Windows 10
You wouldnt install windows 10 on a 1ghz and 1gb ram machine, or? Its just the minimum it can run, nothing more, nothing less.
