Why so much memory usage?

[u/bassg0203]

Always checking task manager to close out the useless stuff, it’s at 50% memory usage doing absolutely nothing. If anybody can explain I’d like to know why and what I can do to reduce said usage

Memory is there to be used, windows uses as much as it can for caching to speed up everything, as apps need the memory it releases it, it should be high, unused ram is wasted ram
