Experts share: win 7 system useless services and process at a glance

win 7 is already a milestone operating system, no matter what aspects are considered very unique, but in fact, win 7 is also designed Some deficiencies, such as some services or processes are unnecessary, these should be disabled.

1.Windows Genuine Advantage (Windows Genuine Advantage)

Windows Genuine Advantage (also known as Microsoft Genuine Verification Program) in Vista is intended to determine whether the Windows system installed on your computer is It is genuine and reminds you to take action, that is, to resist piracy. If WGA detects that the system you are using is not a genuine system, it will take a series of actions on your system. In the early versions of WGA, it would directly deprive you of the right to access the system, which is somewhat sensational, isn't it? Now, WGA is no longer so "severe", if the target user's computer is loaded with pirated Windows, Then every time you start the user, you will be the victim of pirated software, and you can choose to do it later after 5 seconds. Although the window can be canceled by setting, but the verification icon on the tray after booting is not canceled, the verification icon will always exist unless the user purchases a genuine Windows key. Still, the real master knows how to avoid the harassment of WGA, so fundamentally, it has no purpose of existence. In general, WGA is a very impractical feature, and Microsoft should eliminate this annoying feature in Windows 7.

2. Registry

The Windows Registry is a central hierarchical database used in Microsoft Windows 9x, Windows CE, Windows NT, Windows 2000, Windows XP, and Windows Vista for storage. Information necessary to configure a system for one or more users, applications, and hardware devices. The registry contains information that Windows continuously references during runtime, for example, each user's profile, the applications installed on the computer, and the property sheet settings for the document types, folders, and application icons that each application can create, the system Which hardware is present and which ports are being used. The registry is a set of files that control the appearance of the operating system and how it responds to incoming events. These "events" range from direct access to a hardware device to how the interface responds to specific users to how the application works.

When a user is ready to run an application, the registry provides application information to the operating system so that the application can be found, the location of the correct data file is specified, and other settings can be used. The registration table holds location information about the default and auxiliary files, menus, button bars, window status, and other options. It also saves installation information (such as date), the user who installed the software, the software version number and date, serial number, and so on. It includes different information depending on the software installed.

So, the registry is a huge data repository, which stores the various information needed by the operating system and applications to run. Without it, the entire system will be in a state of paralysis. When you use an application to modify the behavior of Windows, it actually modifies the registry at the bottom. However, if you want to make a lot of changes to the system, then you have to edit the registry directly, which is a very cumbersome and highly dangerous thing. Because, with a little carelessness, you will make mistakes, and a small mistake in the registry may cause the entire system to collapse. Other operating systems, such as Apple's Mac OS X and open source Linux, do not have the concept of a registry, and they still perform very well. Microsoft should also consider giving up the use of the registry because it brings too many disasters to the Windows system.
