It looks to me like you are removing a great deal of services, some of which I'm sure are required by Windows to function properly. It's hard to tell, as the services are abbreviated in the Lastsession.ini. In truth, there is very little to be gained by removing most services in terms of hard drive real estate. Perhaps you should simply leave the services section alone completely, then in the tweak section, used one of the "Black Viper" selectable presets on the services tab to disable unnecessary or idle services. Personally, I use the "tweaked" preset.
