Windows 7 services unexpectedly started in Manual mode

hi Windows 7 folks

as i intend to load run a few large virtual machines on my Windows 7 laptop with only 4 GB memory, i am trying to optimise Windows by stopping those unnecessary Windows services to free up more memory. by default, Windows 7 occupies 1.5 GB memory after a restart, before loading any other applications. in the XP age on the same computer, only less than 400 MB memory was used, accordingly.

i notice that some Windows services, as listed below, are still started even i have changed their Start Type to Manual.

* Application Experience
* Background Intelligent Transfer Service
* Server
* SSDP Discovery
* TCP/IP NetBIOS Helper

as shown in the Dependencies tab of these services' Properties, there are no loaded system components depending on these services. moreover, it seems neither item listed under the Startup options of MSCONFIG is associated with these services. therefore, i am curious about how these services are started.

FYI - all started services are listed in the Code section.

any clues? thanks in advance.

regards,
bbao

Wow, that script tool-kit looks brilliant... anyway, i notice it is for XP *only* and i am running W7, which has a number of totally *new* services that do not exist on XP at all...

however, the BlackViper's service configuration guide, which was also suggested by lamaslany, is a great help.

any specific tool (or the CSV file for W7) could be available??

thanks again,
bbao

An update - after configuring the services as per BlackViper's guide, the following services are now NOT started after system restart.

* Health Key and Certificate Management
* Network Access Protection Agent
* Windows Driver Foundation - User-mode Driver Framework
* Windows Defender

however, the following services are still started regardless its Start Type in Manual.

* Application Experience
* Background Intelligent Transfer Service
* Program Compatibility Assistant Service
* Shell Hardware Detection
* SSDP Discovery
* TCP/IP NetBIOS Helper
* WinHTTP Web Proxy Auto-Discovery Service

some of the above services do have dependencies listed in their services properties, but the depended services are not loaded, therefore, theoretically, they should not be started due to the given dependencies.

any clues on why these Windows services are always automatically loaded??

bbao--"Manual" ( as opposed to "Automatic") means that Windows will not start these Services at boot.  But they will be started when an application that requires the service to perform is started.  Such an application does not have to be another Service, which would appear in Dependencies). And that may be started either Automatically or by you at boot.  
You would have to set the Service at "Disabled" to not have it start at all.

hi jcimarron,

thanks for the comments. the point is that, i would like to know which applications/components start those services, as i am currently not aware of this, hence i don't know the impacts of simply disabling those services, if any.

thanks heaps for your valuable comments.

it's a shame that i only have 500 points to give though you all should be awarded 500 points, individually.

@CSI-Windows, as for your Services Optimizer, i am aware that it may support W7 services by customising the CSV files, but as an end user, i do expect a W7 specific CSV file could be directly available... thanks for your support.
