I want to know whether, disabling a Windows service under a User Account is a SYSTEM Wide Change or just for that particular User Account. If change is for the user account, then i want to know which Windows Service's are safe to disable. I'll create a separate user acc. just for GAMING. so i wont be using any thing related to network/internet. i'll disable All start-up prgms. like AntiVirus, FireWall via "msconfig". Also i dont use the Agere Modem in my PC, it occupies a PCI slot. does this modem takes up any resource. NOTE= I've attached a notepad file which contains all the Process's running in my PC. My PC config- HP Pavilion, Softwares== XP Home SP2 (up-to-date), AVG Free, Windows Defender, ZoneAlarm Pro, SpyBot. HardWares== M/B-Intel 915G, Gfx-Intel GMA900(onboard),512MB RAM.
