Win7, Win8, Win10 Impressions

I believe that as a Windows user, you should easily distinguish between the three operating systems Windows 7, Windows 8 /8.1 and Windows 10, especially from the interface design, such as whether there is a start menu or start screen, or whether you can download applications from the Windows Store, etc. Wait. But fundamentally, it's hard to tell the difference between security, performance, and mobility. With the release of the new Windows release, you may know which features have been removed, but the underlying operating system changes dramatically. It's hard to feel. In other words, there is still a day when Windows 10 will be released. What is your impression of Windows 7 and Windows 8?

Windows 7: Faster, smaller Better

Windows 7 was born in 2008. In Windows 7, you can clearly feel the functional changes in the user interface, that is the taskbar. The new taskbar allows you to pin icons and shortcuts to it, with a jumplist showing the most recently used items in the properties, and the most obvious change is the Aero Snap effect in the taskbar. In addition, Microsoft has also carried out a large number of improvements in the underlying operating system, significantly improved security and operational efficiency.

When Windows 7 announced the new minimum hardware requirements, you must have a more powerful hardware configuration to run better. This is completely understandable. After all, this is also in line with the development of Moore's Law, that is, the number of components that can be accommodated on an integrated circuit, which will double every 18-24 months, and the performance will be doubled. The hardware and computer performance that money can buy is more than doubled every 18-24 months.

So, we have seen the popularity of netbooks. Although there are certain performance impacts, mobile computing is becoming more and more common. Moreover, many functions such as Wi-Fi wireless network, Bluetooth connection, mobile broadband and sleep/hibernation have become more and more practical. Microsoft has enhanced the stability of this part of the function, and it is still mobile. Support for touch screens and accelerometers has been added.

At the same time, in order to improve the mobile battery life of Windows 7, Microsoft has also added power management functions, supports BISO or hardware driver management power, and the unused device system can automatically turn off more unnecessary. Something, dynamically adjust CPU performance according to current load conditions and performance requirements, such as reducing CPU operating frequency, reducing so-called idle resource energy consumption, adaptive display brightness adjustment, etc., when there is no task execution, the system is only very low maintenance The power consumption of the operation. In addition, Windows supports interrupting the application's communication with the CPU and will only reconnect after being triggered by some events.

The Windows 7 development process is quite difficult. This is the first time Microsoft has spent five years building the most streamlined and efficient Windows kernel, a minimal kernel project called "MinWin". It is seen as the savior of Microsoft's later years, because the project can help Windows to lose weight and make it easier to navigate. After that, Microsoft can more easily improve the system architecture and add new features to the system without having to Write core services without worrying about breaking the dependencies between the upper API and the core services.

Windows 8.1: Improvements not only for tiles

Full-screen start screens, charms, and full-screen Metro-style tile apps for mobile devices, these are the most obvious additions to Windows 8 And the emphasis on the touch screen function, completely alienated a large number of traditional desktop users. Interestingly, Microsoft has released an ARM processor-based version of the Windows RT system with almost pure Metro elements.

However, Windows 8 actually has a lot of less obvious upgrades, especially the addition of support for new hardware (new hardware), significantly improving security features, such as adding UEFI Secure Boot. Improved biometric security features, firewalls have been updated and enhanced, Windows To Go option supports running Windows directly from a USB flash drive, improving DirectX performance, upgrading Hyper-V virtual machines to the same version as Server 2012, and more.

In addition, Microsoft has improved the power management mode and introduced the Connected Standby connection standby (standby mode) mode, similar to the lock screen standby state in today's smartphones. That is, when the system goes to sleep, the application is suspended, but it will still be connected to the network. This mode is significant in mobile devices, ensuring that emails are not missed or delayed, and that real-time information is always up to date. Windows 8 also monitors the power usage of each component in each PC and then chooses to increase battery life in the most efficient way.

After one year of Windows 8 release, the first major upgrade of Windows 8.1 was released. The upgrade brought back the start button and launched it directly to the desktop. Some changes were made to the Metro interface, but a series of security was added. And management functions to add more new hardware (new hardware) support for enterprise users, such as using Miracast to share screen content to another device and print directly via Wi-Fi.

Windows 8/8.1 starts to deeply integrate OneDrive (formerly known as Skydrive). After you log in to any PC with your Microsoft account, not only the system settings and the applications in the store will be synchronized, you save it in the OneDrive cloud. The file will also be accompanied by synchronization.

Windows 10: Both forward and backward

With the release of Windows 10, Microsoft has a new idea for the Metro app that follows Windows 8, remodeling and naming it generic Applications (Universal apps), which are no longer just full-screen, but run on the desktop like traditional applications and support cross-device operation, including PCs, Windows 10 phones, tablets, Xbox and Hololens. Supports automatic adjustment of interface size to suit various screens according to user device size.

OneDrive is more integrated with Windows 10, and now you can choose which folders need to be synced. The super buttons that appeared on Windows 8 have disappeared, and this has led to an already popular operation center on mobile devices for displaying new notifications and some shortcuts. Windows 10 also brings a brand new browser called Edge, and Internet Explorer will no longer be the default browser, and will only survive on enterprise devices in the future.

At the same time, Windows 10 has brought a lot of security improvements, especially the security features of biometric technology, collectively known as Windows Hello, supporting fingerprint, iris detection and face recognition. Various authentication methods. The performance of Windows 10 has been continuously improved. Now the new system (new system) is installed faster and easier, and it can be automatically cleaned up after installation to free up more disk space.

The Windows 10 user interface has been redesigned to ensure that Windows 10 is suitable for both traditional mouse and keyboard operations, as well as for easy use on touch screen devices such as tablets. Many interface improvements are Based on a mixture of Windows 7 and Windows 8.1, such as the start menu after the regression.

In addition, Windows becomes a service, and you can get new features by continuously receiving new upgrades without having to reinstall a major update of Windows version, which means Windows 10 will be the last Windows version. More importantly, Microsoft wants you to always use Windows on your PC, because new upgrades (new upgrades) and features are automatically pushed to the system, so you don't have to worry about replacing another version of the desktop platform.
