computer slow, trying to check location of csrss

Computer seems to be busy (doing more than my stuff). As per old threads, tried to check csrss location by right click in task manager- but nothing shows; how do I find it's location?

Btw, one of the old comments indicated it was "the only process w/o a description", but I notice conhost.exe has two entries, the first of which also has no description. They have 256k & 264k memory use respectively. Is this odd or a problem?

Much thanks to all

csrss.exe is located in C:\Windows\System32.

Let me search for conhost.exe and I will type the answer.

You have to select "Show processes from all users" to run Task manager with an elevated account. Otherwise it will not have permissions to obtain some information. It is not unusual to see 1 or more entries for conhost.exe. The memory usage for all processes can vary widely. The normal location for csrss.exe and conhost.exe is c:\windows\system32.

Nothing you have described is unusual.

The "Show processes from all users" option is in the Processes tab of Task Manager and it is by no means irrelevant. Without this option you will not see most of the system processes and Task manager will be running with the normal non-elevated account. This account does not have the rights to access some information for some system processes. By selecting this option Task Manager will run with an elevated account which does. When examining system processes this option is a must.

This all assumes you are running with UAC enabled, the default condition.

Thanks for your replies; but I do not see any option or selection possible of "Show processes from all users" no right or left click, scroll, nothing opens up, no selection options, no action visible or audible (no hard drive revving up).

Do please enlighten me, though I suspect something should have popped up, it did not... could this be hidden or disabled by malware?

Btw, does malwarebytes free version conflict w/ avg free version? I recently downloaded Mbytes' and ran it twice in a row, and it did not appear to conflict. Haven't run it since then.

It is a checkbox in the lower left corner of the Process tab of Task Manager.

It is not unusual to have a dozen or more instances of svchost.exe running. I currently have 12 but have seen more. Each instance hosts one or more system services. There are complex technical reasons why this was done. The exact number of running instances can vary from one moment to another as services start and stop.

What you are seeing here is 100% normal.
