svhost.exe always read/write disk
Hi, My windows 7 home premium 64 bit always read/write disk. I have turned off all possible server process. Such as antivirsus, super fetch, and windows search. But it doesn't stop. I use 'procmon' tool and find that it's svhost.exe: 12:41:29.8677386 PM svchost.exe 804 RegQueryKey HKLM\System\CurrentControlSet\Control\DeviceClasses SUCCESS Query: HandleTags, HandleTags: 0x0 12:41:29.8677660 PM svchost.exe 804 RegOpenKey HKLM\System\CurrentControlSet\Control\DeviceClasses\{e2d1ff34-3458-49a9-88da-8e6915ce9be5} SUCCESS Desired Access: Query Value 12:41:29.8677934 PM svchost.exe 804 RegQueryKey HKLM\System\CurrentControlSet\Control\DeviceClasses\{e2d1ff34-3458-49a9-88da-8e6915ce9be5} SUCCESS Query: HandleTags, HandleTags: 0x0 The device instance corresponding to the registry item is: PCI\VEN_8086&DEV_3B64&SUBSYS_036D1025&REV_06\3&11583659&0&B0 Do you have any idea about how to solve it? Thank you!

That is because system services are running in background. To confirm which services are running, please: 1. Open cmd with administrator. 2. Enter: Tasklist –svc 3. Check the services that are load by each svchost process. Is the svchost process slow down the system performance?Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
