90% Memory Usage On Windows 10

I noticed today that I had extremely high memory usage on windows 10 and couldn't find any process that uses a lot of memory.

Here is a screenshot of my memory usage:

And here is a screenshot of poolmon.exe

Can someone please tell me what is causing such high memory usage? Thanks!

Answer

ok, there are several pool tags that are too high.

The PROC usage comes from wscsvc.dll!SetDefenderStatus calls from the security center service in Windows.

The toke usage MpCmdRun.exe (Microsoft Malware Protection Command Line Utility), which is also Windows Defender.

The io tag usage comes from the tool Agent.exe which calls the driver EuPipe.dll. Those files are part of EaseUS Todo Backup ("C:\Program Files (x86)\EaseUS\Todo Backup\bin\Agent.exe")

the SeTd tag is also used by MpCmdRun.exe.

1 large part of the memory usage is the PageTable. But I can't see which process caused it. We had such issues already here and some 3rd party tool caused it. Disable all 3rd party tools/drivers until you found the program that causes the high page table usage.
