Windows 10: Standby RAM not being released after handling files

I've recently noticed that when I move or unzip a file all Free memory gets filled and changes to Standby. The problem is that after the process is done, the standby memory is not released and I have no free memory.I know that there are tools for clearing standby memory but I'm hoping that the root cause is a bug and not intentional design. If that's so what could be the cause?

Gaming, frametimes and not releasing "Standby List" RAM

Clean boot has nothing to do with caching. I am using a minimalistic Windows 10 install regardless, without 3rd party antivirus and the only non-Microsoft drivers loaded are for my motherboard (from Intel) and for my videocard (Nvidia).

This is about CACHING. If you've read the first post, you would see Windows 10 caches files into Standby List from games I have not used in 3 months or more.

This is easy to 100% reproduce by running Battle.Net from Blizzard and allowing to update some games. It will quickly cache huge files into your RAM, not just executables, but those big data files worth hundreds of MB.

Caching like this is FINE.

The issue appears if you have "just" 16GB RAM and you want to launch another game.
Instead of the cached files being purged from RAM, they are kept there and it has a significant impact on performance. You can clear the cached files from RAMMAP by Empty Standby List. This eliminates all issues. There's a DOS command too for
it.

What I am arguing for is smarter cache management from Windows and eliminating the need to manually clear the Standby List (or reboot). Windows 10 should know that a modern game is very demanding on resources and release the large files from cache.

Again, nothing to do with what you normally see in Task Manager. These are programs that are CLOSED, not running at the same time, they are not even launched for months, yet because of some update or scan (Windows Defender, if it scans files, some will land
in cache too...) they are loaded into Standby List RAM and stay there until manually purged or a reboot.

I hope this issue is more clear now.

 

Releasing Standby memory

This is the first I have heard of any issues with Standby list memory causing issues outside of games.
I know there were a lot of reports around 1809 of games having issues where the standby list didn't release memory and games would stutter. There are a few programs that can clear up this issue. I have used both and they do work but I only used it for games, never noticed any issues in windows applications.
ISLC (Intelligent standby list cleaner) by Wagnarsoft and Processlasso by Bitsum can clear the standby list automatically.

 

question on standby memory

It is all in order
Standby memory is ram held in reserve by Windows - for use by the system if needed. - hardware etc.
If processes require more ram than is shown as free, then the standby memory is released by the systme as necessary

With regard to your split second lags, when do these occur - browsing, gaming, etc. More information is required please.
