nearly daily some service is starting a task and never finishs. This task uses an entiry cpu core, which results in high fan activity.

Using ProcessExplorer I found out that it might be a service which is running and never stopping. But I simple can't figure out which service.

From ProcessExplorer it's said:

Command Line: taskhost.exe Time

And

Parent: services.exe(808)

Some help on figuring this out would really be appreciated.

(I already googled a lot, stopped services, looked through all services)

Some information:

  • I'm not sure, but I think the problem is there since I bought the notebook (Dell XPS 12 Duo). Thought it was some Dell or Intel software and removed a lot of the preinstalled things
  • Always had a antivirus software running (Antivir Premiun and now Kaspersky Pure)

After asking the question I've updated the following drivers/software, maybe one of them was the cause:

  • Dell BIOS A04 -> A05
  • Intel Dynamic Platform and Thermal Framework
  • Intel Smart Connect

Update

Still have the issue 3 years.

What else I tried:

  • Complete reinstallation, even used Windows 8 again -> still the same
  • Using Snappy Driver Installer to really get latest drivers
  • Used Linux for a while -> This works, so it is just some problem with Windows

  • I also have a Dell XPS12 with similar issues. Seems to be worst when I open the lid (even though it has not gone into sleep mode). I have SSD and 8Gb RAM, so it should be runnning like lightning. To fix, I need to kill Outlook and then restart it, as that seems the app most affected. But I do not yet think it is the answer. It can take 20 minutes to catch up. I will check my patch and BIOS levels and come back.

Reset to default

services.exe (808) if it is running under C:\Windows\system32\svchost.exe -k DcomLaunch then its a possible sign of trojan or the rootkit which is connected to an external host and trying to suck up the resourses. I would suggest scanning the PC using Hitman Pro or any other good anti-virus in safe mode with networking. You can access safe mode with networking while tapping F8 key during windows startup run the scan only in administrator mode.

  • Thanks for the answer, but doesn't seem to be the answer for me. Did a scan with Hitman Pro and a full scan with Kaspersky. Also the problem seems to be there since I bought the notebook (I will update my question).

Enter system BIOS and reset to default options.

Side note: I'm still using my old XPS, as it is still a very good device. And there still was this issue. Finally I stumbled upon a forum thread where someone suggested to switch some specific setting within the BIOS. My Dell doesn't allow to (nearly) set anything within the BIOS, so I decided to just reset the BIOS to default settings. And voila, this seemed to resolve the issue.
