Making Windows Seven do what you want it to do by tweaking different
services and options.
One of the first thing I do when I setup a new Operating System (OS) is to turn
off unnecessary or useless services. Why? Those services that are set for 'Manual' startup
that never start just take up memory when the computer is started. Even with the
maximum ram you can put in your computer that memory being used by those
services is a waste. Also the processor has to refresh that area of memory
periodically thus using up processor time that could be used somewhere else.
By disabling these services you not only keep them from being loaded in to
memory and eating up processor time you also close security holes that a hacker could
use if the service was loaded but not started.
Here is a list of services that are safe to disable, I have made a list and
of services, and tested them, that can be safely turned off with two exceptions -
Security Center and Windows Firewall which I will explain later.
Tweaking Windows 7 Services you don't have to disable these services,
you can leave them as is. Doing so does use more memory - a lot more, and it
puts you data at risk from viruses and hackers ... Just sayin'.
If you do disable these services you need to consider disabling the
corresponding GP (Group Policy). If you disable a service
for security reasons then leaving the GP at the default setting will allow
someone or a virus to start the service thus defeating you attempt at securing
Troubleshoot, repair, maintain, upgrade & secure...
Note: A hacker that has control of a computer with a Windows Operating System
can conceivably enable a Group Policy, the same for another user with the
correct rights log on rights. But a virus can not enable a GP due to the
complexity of the editor and the security files.
Note: If the computer is in a Domain (ie: Active Directory) then a hacker
that has control of the computer would not be able to start a service that the
DOMAIN GP has disabled! This makes sense if you have the resources to have an
Active Directory Domain!
There are 145 services for Windows 7 and this list shows 22 of them you
can safely disable.
Note: You may not want to disable all of these services, you may need
them such as the Windows Media Center services.
Tweaking Windows 7 Services 64 Bit before disabling the services the OS was
using 460 Meg
of ram, after tweaking the desktop theme and services the OS is using 417 Meg.
Now 43 meg may not sound like much when you have 2 to 8 Gig but that memory is
not open to attack nor is the processor being used to keep the useless data in
memory refreshed. (With anti-virus, trojan, or spyware software installed)
Tweaking Windows 7 Services 32 Bit before disabling the services and tweaking the desktop
the OS was using 335 Meg of ram. After tweaking the OS is using 265 meg a
savings of 90 Meg. (This Win 7 does not have any anti-virus, trojan, or spyware
Note: These memory settings are from Win 7 - 32 and 64 Bit running in a VM
Ware Virtual Computer, physical computer memory will be more because more
hardware drivers will be installed.
The more you turn off that isn't being used will add up in memory and processor
savings. Lower memory and processor usage is lower power usage and lower heat
Security Center and Windows Firewall should only be disabled if
and only if you are behind a hardware firewall such as a router or a Server
with a firewall and proxy services. Do not disable on a laptop that is used at airports, Internet
Cafe's or when traveling.
Normally networks that are isolated from the internet through a
firewall and proxy will have difficulties connecting to the local domain when
the Windows Firewall service is active. One way around this is to write a GPO
that sets the required rules to every computer in the domain. This is a labor
intensive task and needs to be tested thoroughly before implementing in a large
Tweaking Windows 7 like any other Operating System takes time and with
the newer OS's a lot of the services depend on other services. That is if a
service uses another service and that service isn't running then you will
receive an error that the dependency service is not started and the service you
wanted to start failed to start - (Does this make sense to you?) This is why you
can't just go turn off a service because you don't want it to run, you have to
make sure that some other service doesn't need the one you want to turn off.
As always test your settings before going on to the next one, if the service has
a dependency and you turn off all of them at once you will wind up reinstalling

services listed as safe to disable!) and GPO options for
