High ram usage while idle on a windows 11 pc

I running windows 11 22h2 in 8gb RAM but i updated to latest version and started to lagging, when i restart my laptop , not fixed (SO I JUST UPGRADED TO WINDOWS11 GHOST SPECTRE BUT SAME PROBLEM IN WINDOWS 11)

I have the same problem. It is not going away easily; Windows takes up most of the RAM (I have 16 GB), and the memory used up by the processes cannot explain it. On one occasion, Windows sucks up so much memory that if becomes dangerous. Once if happened that my computer became inoperable and it even started to speed up its cooling fan in a dangerous way, because there was not enough memory even for the software that manages the cooling of the hardware.

The thing that helped me is a little app (Ram Booster) you can download in the Windows Store (https://www.microsoft.com/store/productId/9MTRX5VMVZS3). You can set it up to free memory when your used up memory reaches a given percentage. It works fine (I downloaded it for free, but now it seems to carry a small price tag).

On occasion, Windows tries to consume almost all the available memory (for no valid reason at all, of course). When this happens, this little program starts up a battle with Windows; it tries to recover memory while Windows keeps on doing its nasty thing. Happily, after a few minutes of this little war, the memory cleaner wins and the machine becomes stable, with a reasonable amount of used up memory.

Another thing I do to complement this is to boot the machine once a week. This refreshes Windows and it also helps.

What all of you fail to understand is that unused RAM = wasted RAM...

Of course the OS will try to make use of what's available, it's just a good thing. The OS will automatically manage the memory for you. As long as applications are stable and everything runs smoothly, there is nothing to worry about.

Well actually I haven't thought about that.. I have recently built a new rig once again and I just swapped the drive from previous build with Win11 in it and just slammed in x1 stick 4gb ddr3 ram I happened to spare. Surprisingly it worked just fine even though the system specs weren't as preferable ngl. Still more than 50% idle memory going to Com Surrogate or whatever system process in hand, but still not impacting performance so your theory makes sense ig

When looking at the Resource Monitor where is it showing most of the memory usage?

I understand your points, we must find the root cause of the high memory usage applications or services.
