Windows 7: svchost.exe -k netsvcs Slowing Down Computer

It's been doing this for a while now, too..



I don't know if this has anything to do with it, but I disabled windows update a long time ago; if I try to update it now, my system can't handle it, and it reverts its changes.

Help would be appreciated. Where would I start?

start off with SFC /SCANNOW Command - System File Checker

Alright, so I've scanned my computer, though some of the problems couldn't be fixed.
I've heard that an additional scan may solve this to an extent.
Should I post my cbs log? Will that help with anything?

do the SFC scan for 2 more times and you could try Windows Update - Reset

Alright, so I've done the scans and the Update reset. What next? Should I check for updates and download all of them?

did it allow the fixes? have you restarted after the sfc scans? you may check for updates, but download & install the smaller updates first, then go for the bigger ones. not all at once as, you will require a restart after installing them and it may lengthen the installation process. go ahead and keep us posted.

It seems that there's always something to fix, and so I don't know if the scans will end.
I'm planning to use windows update after one more scan. Does it matter which order I download the updates in? Is it alright if I download a new update first, then later an older one?

Hello tyg123 ... if you think any of the processes is slowing down your computer, you should get a virus scan at first, for security. Download malwarebytes antimalware free version, update it and and preform a full scan using it. As you have stopped the updates a long ago, this possibility always exist.

After the malware scan ( you have got the system file checker scan already), update windows. At this point, better you apply all the updates.

I have scanned my computer with MalwareBytes before, and nothing showed up. I'll do it again, but should I do it in safe mode? Will that make a difference?

It is suggested to scan in safe mode when the virus infection does not let you to boot up. If you want , you may run it in safe mode.

I suggested it coz you have stopped updates, and you have some problems with a process. It's just a precaution . Can you tell us what informed you that the process is behind your system's poor performance ? There are a few ways to speed your computer up. Like, run the disk cleanup to remove the junk, disabling startup programs those are not necessary etc. And, if you think that the boot is slow, you can use the boot time deprag option of Puran ( Puran Software - Quality First) .
