7 turns on services when it needs to. DON'T touch them. It will be a nightmare troubleshooting the side effects. Services also depend on other services. Honestly, why are people still concerned with resource usages? Hardware is cheap and you should never bother touching bits of OS to save 3MB. Put in 8GB of RAM, defrag your HDD, or run wiper.exe on an SSD, ensure your PC has enough grunt and get on with your life. 7 knows what its doing. That's what you pay Microsoft for.
With respect.. that is not what I pay Microsoft for. I pay for this system so I can learn about it, then cut 3/4's of it out and rebuild it in my own image.
Do I trust Microsoft to know what's best for the operating system I wish to use? No Way. Not since Bill stole the designs for the winows graphical user interface from Xerox and windows wants to phone home even if you tell it not to.. I use Windows operating systems to take advantage of the little good that's in it. If I were not a hard core gamer, I would chuck this system and use a version of linux.
Unfortunatly, the programs I want to run are made for this platform. When React OS grows up (a free version of windows xp) or Linux or another OS gets the ability to run all Microsoft compatible programs, I will leave MS in the dust.
I'm old enough to remember Microsoft as a small company. I remember all the dirty shady deals they tried to pull to try to get ahead. Most people in the know were shocked they ever made it to the top without some mafia type gangster getting in the way and taking them down. Trust them?? Not as far as you would trust Fidel Castro or Sadam Hussain.
