  1. Thanks for helping me with this. It helped very much in getting rid of the DPS services high memory usage on my PC when I stopped the process however, it still drained power at a high level. Stopping the service didn’t work for me, or maybe I’m just impatient, so I did METHOD 4! Disable the program at startup by opening the services window as shown in method 3 by using the dropdown options in the Startup Type field. Once that is done, restart your computer. It should no longer appear in the processes window. If you no longer wish to have this service taking up 25 gigs on your hard drive delete the .dat file in the system 32/sru folder as explained in method 1.
