On my Dell Windows 7 computer here is what I have done to turn off Dell Datasafe. I do not want to unistall the program, I just do not want it to run, since I do not use it, at least knowingly.

Turn off Dell Datasafe in services. Run

services.msc

Find SoftThinks Agent Service
Right click
Select Properties
Set to run Manual

Turn off Dell Datasafe process.

Right click the Task bar
Start Task Manager
In Processes, right click STService
Stop STService

Seems like there were more processes or services, but I cannot find them now.

You can use Windows Powershell to stop processes.

To turn on Windows 7 Powershell scripts see
www.programmer.bz/Home/tabid/115/asp_net_sql/262/Powershell-Execution-Policy-Warning-Cannot-Be-Loaded-Scripts-is-Disabled-on-this-System.aspx

To create a Powershell script to turn off processes and services see
www.programmer.bz/Home/tabid/115/asp_net_sql/263/Powershell-How-to-Make-Windows-Faster-By-Stopping-Processes-and-Services.aspx

For example, create a file named something like stop-delldatasafe.ps1

# Stop Dell Datasafe
Stop-Process -Name STService

To run it (after following the instructions to turn on Powershell scripts), right click the file and select Run in Powershell.

I may have missed some processes or services, or if you want to stop others, just add them to your script.

Put an icon on your desktop and you can stop them all at once. Each time you reboot you will need to do it again.

I imagine there is a way to have a Powershell script run at start up, but I have not looked into that yet.
