Ok so I'm new to this website so if anything's weird in this post I blame my lack of knowledge on this kind of forums design because I'm so used to XenForo.

So I've been running Windows 10 64x with 8 GB of RAM for a fair bit and it's been running pretty ok, then one day updated Windows 10 64x and seemed to be lagging a bit more than usual. I checked task manager to see what's causing this and I saw my memory at 70% usage then went to see how my PC is doing and saw this - https://gyazo.com/007a894bac8561a373261e4c248491e9
I've pretty much checked every corner of the internet checking what I could do to fix this and all everyone was saying to fix it with was the msconfig thing. I tried going on msconfig and unchecking the maximum memory but it was already unchecked (I can't take a picture with Gyazo for some reason), so I was like ''What the hell can I do now?''
Does anyone know what I can do to fix this?
