For the past couple of days my laptop (ASUS X750JA with Intel Core i7 4700HQ @ 2.40 GHz + 6GB RAM, running 64-bit Windows 10) has been very sluggish, with newly opened windows often showing the 'Not Responding' message. On the Task Manager 'Performance' tab, I see my main hard drive (C partition with Windows 10 + program files; D partition with data) almost continually showing 98-100% active time - even though I'm doing little to nothing and only Google Chrome is running with a few open tabs.
On the 'Processes' tab, I see Dism Host Servicing Process and Modern Setup Host, which I don't normally see. When I manually end Modern Setup Host, hard disk activity immediately drops to, and stays at, the normal 'idling' level of 0-20%, and is mostly at 0%.
Why are these two processes running? I'm not installing anything. My laptop is effectively crippled when Modern Setup Host is doing whatever it's doing.
Please help to restore my laptop and me to sanity. ;-)

Hi Michelle,
Thanks for your suggestions, but they turned out to be off-topic. Dism Host Servicing Process and Modern Setup Host were running to prepare my laptop for the Fall Creators Update, which is now installed. A Windows 10 user who is active on TenForums.com realised this. It seems strange that Microsoft itself can't guess what its own operating system is doing.
Regards,
Rob
Hello Rob,
One of the possible reasons why modern setup host causing 98 -100% disk activity could be due to either be a system configuration error or malware. Having said that, we suggest that you run Malwarebytes and run SFC scan and DISM. You can follow the steps in this article.
If the issue persists, we recommend trying the methods below:
Method 1:
Perform Clean Boot and check if this issue caused due to any third party app/program. Clean Boot will help you determine which app/program is conflicting.
