In this post we will discuss what services in Win7 you can stop to make the system run a bit faster.
I’ve come up with this list after a bit of a research over the net and I will give you my recommendations – Please think twice before you stop/disable any service as it can result in damaging some of your computers features.
So, to make a long story short here is a quick list with services to stop:
1. Diagnostic Policy Service (DPS) – This service is a part of a larger module called the WDI (Windows Diagnostic Infrastructure). The WDI is a collection of diagnostic tools that can help to find many problems that can occur on the any part of the computer (Both HW and SW). The DPS is used to coordinate between the many tools of the WDI to help it find the problems. You can disable this service if you don’t rely on computer itself to monitor itself, but know that all applications that use this service may not function correctly.
2. Computer Browser – This service was a part of windows since early versions of Win2K. It was designed to provide the NetBIOS name resolution. Now day we use DNS for name resolution so this service can be stopped. However, if have any kind of Legacy devices or need to provide backward compatibility on your network do not disable it.
3. Print Spooler – This service is used for printing. Since I don’t have a printer installed I’ve decided to disable it for now. As soon as I get my printer I will enable the service.
4. TCP/IP NetBIOS Helper – This service provides the ability to transfer NetBIOS protocols over TCP/IP protocols. As you recall NetBIOS is no longer used and is replaced by DNS, so you can go ahead and disable it – unless of course you need backward compatibility or have Legacy devices on your network.
5. Media Center Extender Service – This service provides the ability to connected external devices to your computer when it acts as a Media Center. If your computer does not act as one or if does but you do not connect to it any external devices – you can go ahead and disable this service.
6. HomeGroup Listener – This is a new service introduced in Win7 and it is designed to provide computers that are joined to a HomeGroup network the ability to share Pics, Printers and etc…. If you are not connected to any HomeGroup network or if you work with a single computer on the network you can go ahead and disable this service and the one Called HomeGroup Provider. Before you disable those services I suggest you visit the Control Panel, go to Network and Sharing Center, and there you will have the option to leave the HomeGroup (Choose HomeGroup and Sharing options -> Leave HomeGroup). After you leave the HomeGroup, disable the services and you will notice the the HomeGroup shortcut will also disappear from the Windows Explorer.
7. Function Discovery Provide Host – This service is a set of providers that supply network discovery services for SSDP and Web services. You can read about what is SSDP in this article. You can safely disable this service if you do not use your computer as a Media Center.
8. Human Interface Device Access – This service is gives you the ability to press those Hot Keys on the keyboard or other I/O devices like Scanners. If you don’t have any devices that have Hot Keys (like Volume buttons on the keyboard) you can go ahead and disable this service.
9. Peer Name Resolution Protocol – Enables serverless peer name resolution over the Internet using the PNPR. If you do not use Remote Assistance or HomeGroup on your network you can go ahead and disable it. If you disable this service you can go ahead and disable the whole group that contains – Peer Networking Grouping, Peer Networking Identity Manager and PNPR Machine Name Publication Service.
And that’s about it.
Good Luck, and again – think twice before you disable any service!
