how to clear the cached data on the memory(RAM) of the pc windows 10

Ok based on this Thread

Would it be possible to completely remove standby memory ? - Microsoft Community

you might be able to do these steps.

2. Disable Superfetch (SysMain)

Superfetch (now called SysMain) is a Windows service that preloads applications into RAM for faster access. While this is generally helpful, it can increase Standby Memory usage unnecessarily, especially in gaming scenarios.

• Steps:
  1. Press Windows + R and type services.msc, then press Enter.
  2. Scroll down to find SysMain (previously known as Superfetch).
  3. Right-click it and select Properties.
  4. Under Startup type, select Disabled.
  5. Click Stop to stop the service immediately, then click OK.
  6. Restart your PC.

Disabling SysMain may help reduce the amount of memory allocated to caching, reducing the chances of excessive Standby Memory buildup during gaming.

Disabling the sysmain service should give you better utilization of running apps.

HOWEVER!!!!!

removing the standby usage might make first startup of apps to take longer. giving the impression that there is something wrong.

So make a choice and try it both ways, decide which you like better. don't forget to go give William a shout out if it helped you. he's the guy that posted on the other thread.

I had to start some processes to get mine to a state where it was similar to yours.

I Don't know how to answer your question. but to get the nutters like Dave and Chien to look a little more closely at what your problem is, rather than just answering without looking at what you have put up "I hate Microsoft answers", I have included a screen shot with what I think you are talking about. the Cached Data number is the combo of the Modified and standby ram usage. Everything to the right of the line I've circled is what is left of the free ram. The Available number is a misnomer as it include the spaced used by the cached ram is isn't actually available except after certain conditions are met. EG. see the second screen shot

You can also note how the real ram usage is shown on the graph/data on the left but the right hand side only shows and accurate graph but the in use data makes it confusing as to what is actually usable. for me I have 26.2GB of data in use and then 61.9GB of ram that is modified which brings me up to 87 GB of ram that is actually in use.
In your screen shot I can clearly see the line all the way to the right of the memory composition section showing that you have almost all your ram in an unusable state due to it almost all being in a standby state. Ill do some reading, If I find an answer Ill come back and give you a response.

for Dave and Chien benefit I'm going to highlight some things from your screen shot

xZicox usage is the combination of 6GB and 8.9GB which means out of 16GB 14.9GB is in use if xZicox had shown us a full screen shot. that could certainly cause his/her computer to be unstable.

HI, I am Dave, I will help you with this.

In Windows, cached RAM is used to make your apps load and work faster, it should not cause any performance issues on your PC. how much total RAM do you have on your PC?

2

Restart (not shut down) your PC so fast startup is not used, to flush out your RAM to see if that flushes the cached RAM.

thats from my task manager so idk sometimes my PC turns to be slow so I thought it was from the RAM but idk

Thank you for the screenshot, there is no indication of any problem with your RAM usage, it is normal, that will not be causing any performance problems in Windows.
