Defrag issues when system idle ...

After approx 4 minutes of my system being idle, the program 'service host disk defragmenter' starts running using high CPU. I've disabled automatic defragmenting but it hasn't made any difference. As long as the machine is busy it doesn't run ... but after 4 minutes idle, it kicks in. This is a real pain as it means I'm having difficulty watching anything on Netflix, IPlayer etc. Clearly my system is not recognising that there is activity at these times, therefore the defragmenting begins and the CPU usage sky rockets and my fan goes nuts trying to cope. I'm at a complete loss re how to fix this issue. Could someone offer some help? Thanks.

Hey mate, welcome to the forums

Just to make sure, did you check to see that optimization is Off, as in the picture:

You don't have any installed defrag programs or optimizers, right?

Here is a good additional tutorial on how to potentially make windows 8 run a little faster, you might enjoy having a look: http://www.eightforums.com/tutorials/37511-optimize-performance-windows-8-a.html

I don't have an 8 install to check, and haven't used 8 in a few weeks, so memory is a little fuzzy, but there might be some entry in Task Scheduler to look at and disable. Worth a check in any case.

taskschd.msc

Also not sure what you've disabled, but if you didn't mean services.msc, check there too. For 8: Optimize Drives service. (defragsvc)

I'm having this same exact problem also. I've made sure to disable my optimizations. I use my laptop for music production and this spike in CPU usage causes my sound card to crash exactly when the "service host disk defragmenter" starts to run. I checked the services and disabled the "optimize drives." Looked at the task scheduler and didn't really see anything. Any ideas? Thanks!

By 'disable my optimizations', what do you mean? Do you mean the disk drive optimization was turned off (as in my picture posted above)?

Did you follow my link at the bottom of my post above?
