Foreign media summary: Windows 7 is better than the other four factors of the system

Windows 7 is more modest in terms of performance and security than Vista. But because XP has slowly been unable to adapt to the latest hardware and network technologies, most companies feel that it is time to consider Windows upgrades. With the introduction of Windows 7, it is indeed necessary for companies to start testing new operating systems.

In October, XP will celebrate its eighth anniversary. From a hardware perspective, this operating system is no longer the best choice for multi-core systems and 64-bit architectures, but from current network technologies, such as For IPv6, ISCSI, it is not the best choice.

The most compelling aspect of Windows 7 is undoubtedly the revised Aero interface. The Aero Peek small drive taskbar has access to sleep programs; the new Jump Lists provide quick access to program-specific documents and history; the library extends the reach of computers and networks, and many programs and files can be accessed with just a few clicks use. But GUI updates are not the reason for companies to embrace new operating systems.

For these consumers, Windows 7 has many features -- including DirectAccess and BranchCache -- that are designed to work with the latest upgraded servers and domains. Windows Server 2008 R2 runs.

Installation

Microsoft offers two Windows 7 installation methods: custom installation and upgrade installation. However, because there are not many computers that meet the upgrade installation, most people will still choose a custom installation.

For example, upgrading from XP to Windows 7 requires a custom installation because XP does not have any environment suitable for direct upgrades. Users who have to upgrade from 32-bit Vista to 64-bit Windows 7 also have to choose a custom installation.

Only when the Vista and Windows 7 architectures are the same (32-bit to 32-bit, 64-bit to 64-bit) are suitable for the upgrade installation. Even so, there are other restrictions on the upgrade installation. Because users can't convert to the lower version: if the user is currently using Vista Ultimate, they can't upgrade to Windows 7 Home or Professional. Instead, users can upgrade from Vista Home Edition to Windows 7 Ultimate, and it's important to note that users cannot upgrade from Vista Ultimate to Windows 7 Enterprise.

As part of a custom installation, users must first choose to reinstall all apps. Before starting a custom installation, we recommend that you place a Windows 7 or Vista compatible driver for your network adapter on a USB stick. Windows 7 does not guarantee that all information is intact - the custom installation process will capture the old system's C drive and save it in an upgrade system called the Window.old folder.

In addition, Microsoft provides a link to the Windows Upgrade Advisor, which scans for programs and drivers that are not compatible with the current system. At the very least, users are concerned that their current anti-malware suite does not support Windows 7, so it is recommended that you remove such programs before the upgrade - even if the upgrade consultant only reports the problem as a potential threat to the user.

We tested 32-bit and 64-bit Windows 7 Ultimate and Vista SP2 Ultimate on two machines.

The first machine represents the current common notebook configuration: Dell XPS M1330, 3G RAM, 2.6GHz dual-core T9500 processor, 160GB hard drive and Nvidia M8400 graphics chip. The other system represents a high-end desktop: 3.0GHz quad-core Phenom II 945, 1066 DDR3 4GB RAM, 1TB hard drive and ATI Radeon HD 4870 X2 graphics.

At least from the optical media source, Windows 7 simplifies the installer provided by Vista. After the user logged into the system and contacted the client hardware system, we tested the process. On Dell laptops, 32-bit Windows 7 installation took 21 minutes, while Vista SP2 took 32 minutes; 64-bit Windows 7 took 28 minutes, and Vista x64 took 30 minutes.

On the desktop, the installation speed is very fast, and Windows 7 performs well again. 32-bit Windows 7 took 15 minutes, while 64-bit Windows 7 took 18 minutes. Vista 32-bit and 64-bit installations are 18 and 19 minutes, respectively. It takes longer to upgrade the installation, which takes about 45 to 60 minutes.
