Hi,
Can anyone tell me what the 'Data Sharing Service' (dssvc.dll) actually do?
I've disabled it through msconfig , and my system runs fine. But it does sound a bit intrusive. So what does it do?
Also what does the 'DataCollectionPublishingService' do? Can i disable it also?
THX!

Hi Jesper,
I have checked the file size from my machine and it is only about 1M.

Hi Franky99,
The Data Sharing Service provides data brokering betweem applications and it is running as LocalSystem in a shared process of svchost.exe. Other services might run in the same process. If Data Sharing Service fails to load or initialize, Windows 10 start up proceeds. Make sure that the DsSvc.dll file exists in the %WinDir%\System32 folder.
"DataCollectionPublishingService" supports first party apps to upload data to cloud.
Considering they are both belonged to the system files, it is not recommended to disable them directly. Disabling them may result in unexpected behavior.
Would you please share us the exact issue you have come across?
If the issue is related to these services, please take the following steps to have a troubleshoot.
1.Run "dism /online /cleanup-image /restorehealth" to check the health of system files.
2.Perform a clean boot to have a troubleshoot whether this issue is caused by the third party serivce conflict.

Any idea why DsSvc.dll would be doing this?
Upgraded to Win 10 a week ago, no new apps (apart from W10), and this 100% disk usage keeps happening:

Also, is DSTokenDB2.dat in the same directory supposed to be 1.2 GB ?

To whom is may concern,
One cause can be Virtual Memory, which uses the hard drive as if a set part of it were RAM. Virtual Memory was around long before windows 10 (including in windows 7).
Virtual Memory is useful during a BSOD (Blue Screen Of Death) and other errors that normally generate 1 or more log files. If your computer crashes and there is not enough Virtual Memory, Windows will not generate a log of the crash.
P.S. This may not be the reason you are seeing increased usage in your hard drive, but it is worth considering.
Food for thought,

You could look into the DSS.log file, this could give a hint.
