File Explorer Memory Leak?

Online searches indicate the issue I've just identified is common, and that the only way to stop it is to kill the process when RAM usage gets too high for comfort...and picking the right "explorer.exe" process to kill so you don't close the taskbar.

It's probably been here a while but I just noticed how each time I open File Explorer it uses a little more memory and each time it is closed, a process remains open but that the amount of memory released decreases....i.e. each time I open and close File Explorer the amount of RAM used (active and when closed) gets larger.

Is there a fix or setting to stop this? I assume the process stays active even when closing the app to help it open faster next time? or is it a bug? Same for the memory leak. I've run Windows Defender, Malwarebytes, and even ESET online scanner, and no indication of malware. Likewise, I looked in Autoruns and don't see any rogue extension that would cause this behavior.

I wonder if this is related to this thread.

You could be right..same probem found on my laptop. Could be memory leak caused by most recent update. Looks like this is expected behavior. App works fine...just the memory growth.
