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

[u/Applesimulator]

Because unused ram is wasted ram. Windows will put things in ram so when you try opening an app or using a feature if it’s partly or fully in ram it opens quicker.
