Why does Windows 11 keep using more and more ram the longer it's on?

I have 128GB of ram and it slowly creeps up until it's full and nothing is running, I look at task manager and according to that I'm using barely anything. I've tried reinstalling a fresh install, but Windows 11 always does this and the problem is it slows the whole thing down over time. I'm someone that likes keeping their PC on 24/7, so right now it's been on three months, but that is no excuse to be using all my 128GB of ram. My Macbook hasn't been off since I bought it in 2020, yet that is still fine, it is barely using anything still.

What is Windows doing? Cause Resource Manager and Task Manager do not show what is really going on.

As mentioned above, is it actually being "used" or is it just part of the cache?

If a program is gobbling it up then you can see that in task manager (expose the commit size column in the details tab, if you're not sure).

Browsers can slowly consume your memory if left open (never closed) and you don't restart the PC regularly.

The cache is not a problem, you'd usually want that memory to be used because it improves responsiveness and loading times.

To be blunt, 3 months is a VERY long time for any OS to be up for (assuming that's without a restart) and in my experience, many programs have poor memory hygiene if they're left open.

I cannot find out where the memory is going, resource monitor and task manager both do not say anything, I cannot find out where it is going.

Is there a way to clear the cache without restarting to see if it's that?
 
Nvidia was using a lot of ram but I install the version with all that crap taken out now so it's just a pure driver and have gone through several updates. I have nothing installed other than Steam and that isn't doing it :/ Something weird in Windows, it must be caching but it just isn't telling me, I use a really small C drive partition so if Microsoft decide to active updates again it cannot physically do it. So I'm thinking it's going to my ram instead of my drive maybe?

The only thing that Process Explorer showed was several GB in memory compression and everything else was that svhost thing. I just cannot see where it is going, the only thing is restarting Windows.

Ah your small drive C partition is likely the cause of problem. Is drive C size 250GB? That size is too small to use file paging for Windows virtual memory. It probably explained your Windows 11 used whole 128GB RAM as virtual memory.

I recommend you to get large 2TB SSD for OS drive to mange large virtual memory for 128GB RAM.

I wont be doing that, I just need Nvidia to support Linux properly so I can switch there, Microsoft do my head in. What would be good is allowing me to flush the cache instead of having to restart but Task manager isn't showing that much cached, only several GB.

I dunno what is going on, I'm done with Windows tbh, it wouldn't be so bad if they didn't force updates. So many times I've been away to find out my PC has updated and I cannot remotely access it until I get home. You can only push them back for so long before they force you and so why I had to install a custom version with all the updates disabled. However in the past it has somehow magically turned the updates back on, which is why I only have a few hundred MB free so it cannot update at all.
 
I'm sitting here now since I posted 96GB committed despite nothing being open... Ok fine, I dunno what it's committed to? Windows doesn't tell you. In use 64.8GB, again nothing is open, Avalible 57.2GB... Paged Pool 3GB non paged pool 4.6GB and cached 51.6GB.

My PC is slow as crap.

I'm going to install Windows again and I'll find it doing the exact same thing.

It just slows down for no reason....

Windows sucks, sorry to the fans but it's so bad!
 
Task manager says 34.6GB being used despite all that. How the hell is that much being used with nothing open? I've gone through all the processes and I literally cannot shut a single thing down other than Firefox and that only removes a couple GB.

Things like that are pointless. The operating system is intelligent enough to know that data cached in RAM can be redirected to the currently active task or application. By clearing the cache manually you are actually making your system slower not faster as the operating system has to pull data from the SSD / HDD which is much slower than getting it from a RAM based cache.

It doesn't work anyways, it shows ram being freed and then it comes right back again seconds later.
 
Private process is 3GB in active 27GB says unused :S Makes no sense. Page tale is 16.6GB.

None of this means anything.

Why does my PC slow down over time and I have to reset it? There is nothing installed on it but Steam and I've installed Windows many times and it does the same thing.

I can only assume everyone shuts their PC down, but I do not want to shut it down, I like it being on! Again I've had a Mac for years and never turned it off, it never slows down. In fact my phone has been on since I got it in 2020 and it hasn't slowed down, I haven't even updated it because I didn't like the changes in a newer version.
