svchost.exe (netsvcs) using DataStore.edb

My PC seems to access DataStore.edb a lot, bringing my hard drive to a crawl for minutes at a time. It happens when I first boot up, and on and off as I use it throughout the day. What is triggering this to be accessed? Is there anything I can do to minimize this file being accessed so often? (no viruses - I already scanned for viruses).

I already put the datastore files on my Avast exclusion list, as I've read that antivirus scanning those files can tie up the system.

I also just installed optional Windows Update KB3050265 as I read it fixes a major issue with Windows Update tying up system resources.

Is it correct that this file is tied into the update service? if so, would it make sense to disable the Windows update service and only manually enable it just to update my PC when needed rather than leaving it on?

It doesn't make sense to disable windows updates - for security reasons. You can try Brink's fix here:

Windows Update - Reset - Option 3

If that doesn't work you can try another fix but please do not go ahead unless you have a system image backup and know how to restore the backup.

Note: The Windows Update download links and force install instuctions relate to Windows Update Agent 7.6.600.320 and as you have installed Windows Update KB3050265 which adds improvements for those wishing to upgrade to Windows 10 - those instructions probably don't apply unless you can find a standalone installer for whatever version of Windows Update Agent that you have currently installed.

Fixes included in this update
This update addresses an issue in which system performance can be decreased during scans. This issue has the greatest effect on computers that have a small amount of physical memory.
This update addresses an issue in which Windows Update scans can fail and generate a 0x8007000E error.
General improvements are made to support upgrades to a later version of Windows.

Also note: You may need to run the Hotfix in aggressive mode two or three times with a reboot each time for the settings to take effect.

Another option would be to remove KB3050265 using Powershell.

For me personally - Windows Update Agent is 7.6.600.320 and all Windows 10 Upgrade updates have been removed.

Also note: If you have hidden any windows updates they will install automatically after applying the fixes unless you configure windows update setting to "Check for updates but let me choose whether to download and install them"
