Huawei mobile aircard sold by True Mobile in Thailand has this software. I have two instances of this process running simultaneously so wanted to research. Not sure what this is doing or why it is running 2 identical processes (size and location)

I have this running and I have an O2 UK dongle
I have an O2 Huawei dongle. Today 2 instances of DCSHelper were running, one using all of one core. Closing the connection manager client, then stopping the DCSHelper processes, then reopening the connection manager made the problem go away
Since as it says above as well: "It can change the behavior of other programs or manipulate other programs. DCSHelper.exe is able to record inputs and monitor applications." And it has a variable low to high CPU utilization even when the Huawei device is not connected. Also Huawei is known to be closely connected with China's military, and banned in many countries' state communication. These drivers are likely "multi purpose".

You need it if you have a 3G USB Dongle from Huawei for accessing the internet.
When laptop slowed down dramatically, I noted in Task Manager that DCSHelper suddenly started using 50% of my CPU non-stop. I tried closing it without success. I then traced its location to computer local disk(C: programdata datacardservice. I then uninstalled the comms apps that uses the Huawei 3G dongle. This terminated DCSHelper as well as removed it from the above directory together with DCService and other bits and pieces. Problem solved. I also deleted the datacardservice directory from programdata. I did not re-install the 3G dongle software as I no longer use it. Hope it helps for you as well.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command.
