Two conhost.exe, one csrss.exe, one winlogon.exe, all (but one conhost.exe) have no location

Recommended Posts

As I was looking through my Task Manager, I noticed something odd. There were two conhost.exe running. One of them didn't have a file location, description, or even a user name (well, SYSTEM, but not really). Showing all processes made it decide that it had a description. It was also using more memory. The one that was selected didn't reveal a location. Look at the first and second image ("Windows5", "Windows10"). TaskMan (not Task Manager) revealed that the one using less memory was in System32. The other one was in my user folder ("Windows11"), but when I looked, there was nothing new.

Showing all processes also made another csrss.exe appear, which was also using a lot more memory, but I don't think (keyword: think) that's an issue. As for the actual csrss.exe that was running, it didn't reveal a location either ("Windows6"). When showing all processes, both csrss.exe were were claiming to be running from the System32 folder, but so were the two conhost.exe.

The winlogon.exe didn't have a location, TaskMan was also claiming it was in my user folder. (Simple picture to help: "Windows8".) Showing all processes made it give a location.

(Picture to illustrate conhost.exe and csrss.exe: "Windows2", and a picture for winlogon.exe: "Windows4".)

Also, noticed that TaskMan was claiming there were two nvwmi64.exe running, while Task Manager claimed one, but showing all processes revealed another ("Windows3", "Windows7", "Windows12").

Don't worry about the picture naming scheme. The numbers were the order I took them in; nothing else. I left out 1 and 9 because they turned out to be irrelevant.

As a note, Kaspersky and Malwarebytes scans came back clean. My computer appears to be operating normally with no kind of slowdowns. The only problem is the mouse sometimes acting up, but this is the mouse's fault.

If this is Windows being rude, then sorry for wasting your time. But I don't really think it's the fault of Windows. I've read other posts where the processes didn't have a location, like now, and they actually found something. Help is appreciated.

Actually not necessarily anything wrong based on that. Depending various factors the path in different programs may not be shown or may be locked from showing.

We can go ahead though and run some scan to ensure the system is clean.


We'll skip the first 3 steps and move on to the 4th step

Please go ahead and run through the following steps and post back the logs when ready.

Please download Junkware Removal Tool to your desktop.

  • Shutdown your antivirus to avoid any conflicts.
  • Right click over JRT.exe and select Run as administrator on Windows Vista or Windows 7, double-click on XP.
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next reply message
  • When completed make sure to re-enable your antivirus

Lets clean out any adware now: (this will require a reboot so save all your work)

Please download AdwCleaner by Xplode and save to your Desktop.

  • Double click on AdwCleaner.exe to run the tool.
    Vista / Windows 7/8 users right-click and select Run As Administrator
  • Click on the Scan button.
  • AdwCleaner will begin...be patient as the scan may take some time to complete.
  • When it's done you'll see: Pending: Please uncheck elements you don't want removed.
  • Now click on the Report button...a logfile (AdwCleaner[R0].txt) will open in Notepad for review.
  • Look over the log especially under Files/Folders for any program you want to save.
  • If there's a program you may want to save, just uncheck it from AdwCleaner.
  • If you're not sure, post the log for review. (all items found are adware/spyware/foistware)
  • If you're ready to clean it all up.....click the Clean button.
  • After rebooting, a logfile report (AdwCleaner[S0].txt) will open automatically.
  • Copy and paste the contents of that logfile in your next reply.
  • A copy of that logfile will also be saved in the C:\AdwCleaner folder.
  • Items that are deleted are moved to the Quarantine Folder: C:\AdwCleaner\Quarantine

Unless you're actively coding in this very old version of Java I would recommend that you uninstall it.

Java SE Development Kit 7 Update 55

Let's go ahead and run one more scanner just to make sure, but so far nothing really wrong found. Just a bit of paranoia is all :-)


Please visit this webpage and read the ComboFix User's Guide:

  • Once you've read the article and are ready to use the program you can download it directly from the link below.
  • Important! - Please make sure you save combofix to your desktop and do not run it from your browser
  • Direct download link for: ComboFix.exe
  • Please make sure you disable your security applications before running ComboFix.
  • Once Combofix has completed it will produce and open a log file.  Please be patient as it can take some time to load.
  • Please attach that log file to your next reply.
  • If needed the file can be located here:  C:\combofix.txt
  • NOTE: If you receive the message "illegal operation has been attempted on a registry key that has been marked for deletion", just reboot the computer.

You should uninstall this. No program should be installed and running from the TEMP folder. Temp if for temporary, ie, trash.

R3 cpuz138;cpuz138;c:\users\Parker\AppData\Local\Temp\cpuz138\cpuz138_x64.sys;c:\users\Parker\AppData\Local\Temp\cpuz138\cpuz138_x64.sys [x]
R3 cpuz139;cpuz139;c:\users\Parker\AppData\Local\Temp\cpuz139\cpuz139_x64.sys;c:\users\Parker\AppData\Local\Temp\cpuz139\cpuz139_x64.sys [x]


If you want to use it then extract the file from the zip to it's own folder and create a shortcut for it.

Aside from that I'm not really seeing anything out of the ordinary.
