Windows 10: Processes causing high CPU use in Windows 10
Processes causing high CPU use in Windows 10
I had mentioned in an earlier post that since I upgraded a laptop to Windows 10, the CPU fan kept running on high all the time. I found out the cause of the problem were these two background processes:
From Microsoft Background Task Host - backgroundTaskHost.exe
From Microsoft Download/Upload Host - BackgroundTransferHost.exe
They are both located in the C:\Windows\System32 folder and whenever they run, which happens at seemingly random times, CPU utilization goes up to 60 or even 80%.
Does anybody know what these processes are for, or how to disable them to prevent them from running?
Process Explorer should tell you what the problem is.
Go to Settings, Update & security, Windows Update, Advanced options,
Choose how updates are delivered, Updates from more than one place.
Turn the switch OFF.
Now your laptop won't be revving the CPU to share updates in the background with other computers.
Yes, I do have that program, thank you.
But I'm not trying to determine which processes are causing high CPU use. I already know it's those two processes. Rather, I want to find out if I can prevent them from running.
It did occur to me that it had something to do with that setting. So the switch is already off, but they keep popping up.
With the switch set to OFF your laptop will still get updates, it just won't share them with anyone else.
It's probably something in your startup disable everything but your AV.
No, I meant the processes still pop up, as in the Task Manager.
Well, I still haven't found out what these two processes are for. One reply that I did get in another forum saying that these processes "finish building install caches, optimizing system files, and downloading patches" seemed very vague.
I also found other instances of people noticing a process called "Photos Background Task Host" use up a lot of CPU, and another one who noticed a process called "Facebook Background Task Host" in Windows 8.1, although this one did not specifically mention that there was a high CPU use.
Could these two processes have something to do with Windows Store apps? Who can tell me... ?
Yes, they do what they say on the tin: host apps running in the background.
Go to: Settings->Privacy->Background Apps and turn all that nasty crap off.
Restart your PC and see if the situation has improved.
If not then something else is running in the background.
If I turn "all that nasty crap" off, will apps still be useable, update and the like when I use them? I don't need these apps working in the background, but I want them to work as usual when used.
I have a PC with Asus P9X79 Deluxe motherboard. It has Intel chipset and Intel BIOS RAID (RSTe) and 6 SATA ports connected to it. The chipset IDE controller lists in Linux as:
Intel Corporation C600/X79 series chipset SATA RAID Controller...
So currently I have 70 processes in the background running.
A tad high for my taste and given I am not running on top of the line hardware It feels like I hit the cap a lot sooner now then I did on 8.1
With Firefox, Steam and Skype running, My...
Seems that mpc-hc causes issues on the task bar, and the start menu.
