Mac OSX Leopard Snow vs Windows 7

AppleInsider has published an in depth look at the competitive origins of Windows 7 and Mac OS X and why the products aren’t really direct competitors.

The operating system most users end up with will depend upon what hardware they choose to buy, not the specific feature details of the software that system happens to run. History reveals that the hardware decision isn’t going to be based primarily upon features.

The following presents a historical overview of the competition between Apple and Microsoft in the operating system market leading up to this year’s face off between Windows 7 and Snow Leopard. While modern Macs can now also run Windows, Apple is the only PC maker to refrain from actually licensing it from Microsoft as an OEM; in contrast, Apple’s Mac OS X only legally runs on the company’s own premium PCs. That has enabled Mac OS X to differentiate Apple’s hardware from other PC vendors using easy to demonstrate software features and tighter hardware integration, winning back some of the ground Apple lost during the decade of the 90s.

Force a shutdown in Windows

rundll32.exe shell32.dll,SHExitWindowsEx 4

The above will shutdown any running processes and shutdown your computer without saving any data or warning. It should only be used if you have problems shutting down normally.

Note the numbers at the end of each of the above command lines. They are what make the different actions possible and they can be combined. The most common combination is using the Force shutdown action with a restart. Restart = 2 Force =4, so you would just add 6 to the end of the main command line:
rundll32.exe shell32.dll,SHExitWindowsEx 6

If your computer supports the power-off feature, you can also use the number 8 which is a Power Off action which will not only shutdown your computer, but turn off the power too.rundll32.exe shell32.dll,SHExitWindowsEx 8

To summarize:

0 = Logoff
1 = Shutdown
2 = Restart
4 = Forced Shutdown
8 = Power Off (Shutdown and turn off Power)

What is svchost.exe And Why Is It Running?

You are no doubt reading this article because you are wondering why on earth there are nearly a dozen processes running with the name svchost.exe. You can’t kill them, and you don’t remember starting them… so what are they?

So What Is It?

According to Microsoft: «svchost.exe is a generic host process name for services that run from dynamic-link libraries». Could we have that in english please?

Some time ago, Microsoft started moving all of the functionality from internal Windows services into .dll files instead of .exe files. From a programming perspective this makes more sense for reusability… but the problem is that you can’t launch a .dll file directly from Windows, it has to be loaded up from a running executable (.exe). Thus the svchost.exe process was born.

Why Are There So Many svchost.exes Running?

If you’ve ever taken a look at the Services section in control panel you might notice that there are a Lot of services required by Windows. If every single service ran under a single svchost.exe instance, a failure in one might bring down all of Windows… so they are separated out.

Those services are organized into logical groups, and then a single svchost.exe instance is created for each group. For instance, one svchost.exe instance runs the 3 services related to the firewall. Another svchost.exe instance might run all the services related to the user interface, and so on.

So What Can I Do About It?

You can trim down unneeded services by disabling or stopping the services that don’t absolutely need to be running. Additionally, if you are noticing very heavy CPU usage on a single svchost.exe instance you can restart the services running under that instance.

The biggest problem is identifying what services are being run on a particular svchost.exe instance… we’ll cover that below.

If you are curious what we’re talking about, just open up Task Manager and check the «Show processes from all users» box:

Vista task manager

Vista task manager

Checking From the Command Line (Vista or XP Pro)

If you want to see what services are being hosted by a particular svchost.exe instance, you can use the tasklist command from the command prompt in order to see the list of services.

tasklist /SVC

cmd Window

cmd Window

The problem with using the command line method is that you don’t necessarily know what these cryptic names refer to.

Checking in Task Manager in Vista

You can right-click on a particular svchost.exe process, and then choose the «Go to Service» option.

Task Manager

Task Manager

This will flip over to the Services tab, where the services running under that svchost.exe process will be selected:

Task Manager

Task Manager

The great thing about doing it this way is that you can see the real name under the Description column, so you can choose to disable the service if you don’t want it running.

Using Process Explorer in Vista or XP

You can use the excellent Process Explorer utility from Microsoft/Sysinternals to see what services are running as a part of a svchost.exe process.

Hovering your mouse over one of the processes will show you a popup list of all the services:

Process Explorer

Process Explorer

Or you can double-click on a svchost.exe instance and select the Services tab, where you can choose to stop one of the services if you choose.



Disabling Services

Open up Services from the administrative tools section of Control Panel, or typeservices.msc into the start menu search or run box.

Find the service in the list that you’d like to disable, and either double-click on it or right-click and choose Properties.



Change the Startup Type to Disabled, and then click the Stop button to immediately stop it.



You could also use the command prompt to disable the service if you choose. In this command «trkwks» is the Service name from the above dialog, but if you go back to the tasklist command at the beginning of this article you’ll notice you can find it there as well.

sc config trkwks start= disabled
