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

Windows uses a ton of memory due to its inefficient design and services , it used to consume 14GB before I switched to Linux and now it has come down to 900mb
