Three Major Differences between Windows 8 and Windows 7 ‰ÛÒ Security Design Version

I believe you have seen a lot of articles about difference between Windows 8 and Windows 7. Now I summarize three major differences between them. Hope it could make you become more familiar with two present popular Windows operating systems, Windows 8 and Windows 7.

Windows 8 provides four different versions, Windows RT, Windows 8 Standard, Windows 8 Professional and Windows 8 Enterprise. Windows RT is designed for tablet, and other three versions are available for PC

Up to now, a lot of people still think that Windows 8 is the upgrade version of Windows 7. Actually, it is not true. So whatÕs the difference between Windows 8 and Windows 7?

1^stDifference: Version difference between Windows 8 and Windows 7

When Windows 7 was released, it is divided into several versions, including Home Premium, Ultimate and Pro. Why Microsoft divides Windows system into so many versions? The most important reason is in order to satisfy computer usersÕ especial demand. Just like the four versions of Windows XP, Microsoft also divides Windows 8 into four versions.

Windows RT will be installed in tablet or PC with ARM processors. And Windows 8 Enterprise is mainly in the face of enterprise and their employees, which bound to a large number of enterprise applications. Therefore, for general computer users, if they want to upgrade Windows 7 to Windows 8, Windows Standard and Pro are the best choice.

2^ndDifference: Design Difference between Windows 8 and Windows 7

If you have tried to use Windows 8, you should know design of Windows 8 is so different from previous Windows systems that we may think it should not be Windows OS for computer.

1. Compared to Windows 7, Windows 8 preview keeps the similar layout of the traditional interface.

Status bar of desktop still keeps the Aero Glass Affection. And the default background takes Beta fish into use which couldnÕt show technology period feel.

2. Start button is cancelled in Windows 8 at last.

3. Windows 8 will split the Control sidebar in the left button. And the traditional left button of the desktop will become a quick entrance to Metro surface.

4. Compared with developer preview, the consumer preview of Windows 8 enlarges button in control sidebar, which makes touch-based operation convenient.

5. In Windows 7, the composite keys of Win and Tab let us know about the layout of 3D effect. But in Windows 8 consumer preview, the page switch mode of the keys combination changes.

6. In the design of Ribbon sidebar, Windows 8 consumer preview make options more easy-to-use and rich like Office, at the same time, the developer version will become easier to use too.

7. In Windows 8 consumer preview, when users are ready to delete something, the system will not give users a hint just like Windows 7 to make a final decision. Instead it will be made by Empty Recycle Bin. This improves effect of Windows system.

8. In Windows 8 consumer preview, the label page of external device, such as USB, connecting with computer is similar to Metro UI experience.

9. During the process of copy and paste in Windows 8, computer user could decide suspend the process, which becomes more humanized than in Windows 7.

10. Windows 8 consumer preview improves task manager by integrating simplify with graphicalization.

3^rdDifference: Security Difference between Windows 8 and Windows 7

This part mainly talks about 6 more advanced security settings in Windows 8 than Windows 7.

Whatever you think of it, Windows 8 isnÕt just a new interface slapped on top of Windows 7. Windows 8 has seen a lot of security improvements, including an integrated antivirus, an application reputation system, and protection from boot-time rootkits. There are also quite a few low-level security improvements under the hood. Microsoft hasnÕt spelled out all of them, but Windows 8 manages memory in a more secure way and includes features that make security vulnerabilities harder to exploit.

1. Integrated Antivirus

Windows 8 finally includes an integrated antivirus program. ItÕs named Windows Defender, but the interface will be immediately familiar to anyone thatÕs ever used Microsoft Security Essentials Ð this is Microsoft Security Essentials with a new name. You can easily install any other antivirus you prefer and Windows Defender will be automatically disabled if another antivirus is running, but the integrated antivirus is a capable product. Best of all, this ensures that all Windows users will finally have antivirus protection out-of-the-box.

2. Early Launch Anti-Malware

In Windows 8, antivirus products can start earlier in the boot-up process to scan the systemÕs drivers for malware. This helps protect against rootkits that start before the antivirus program and hide from it. Windows Defender starts earlier in the boot process out-of-the-box, and third-party antivirus vendors can also add the Early-Launch Anti-Malware (ELAM) feature to their products.

3. SmartScreen Filter

Previously used only in Internet Explorer, the SmartScreen filter is now implemented at the operating system level. It will be used to scan EXE files you download from Internet Explorer, Mozilla Firefox, Google Chrome, and other programs. When you download and double-click an EXE file, Windows will scan the file and send its signature to MicrosoftÕs servers. If the application is known-good, such as the installer for iTunes, Photoshop, or another popular program, Windows will allow it to run. If itÕs known-bad, perhaps if it contains malware, Windows will prevent it from running. If itÕs new and Windows doesnÕt know what it is, Windows will warn you and allow you to bypass the warning.

This feature should help less-experienced users from downloading and running malicious programs from the Internet. Even new pieces of malware will be detected by the SmartScreen filter as an unknown new program that should be approached with caution.

4. Secure Boot

On new Windows 8 computers that use the UEFI firmware instead of the old-style BIOS, Secure Boot guarantees that only specially signed and approved software can run at boot. On current computers, malware could install a malicious boot loader that loads before the Windows boot loader, starting a boot-level rootkit (or Òboot kitÓ) before Windows even launches. The rootkit could then hide itself from Windows and antivirus software, pulling the strings in the background.

On Intel x86 PCs, youÕll be able to add your own security keys to the UEFI firmware, so you could even have your system boot only secure Linux boot loaders that youÕve signed.

5. Memory Management Improvements

Microsoft has made a lot of under-the-hood improvements to the way Windows 8 manages memory. When a security hole is found, these improvements can make the security hole harder or even impossible to exploit. Some types of exploits that function on earlier versions of Windows wouldnÕt function at all on Windows 8.

Microsoft hasnÕt spelled out all of these improvements, but they have mentioned a few:

ASLR (Address Space Layout Randomization) has been extended to more parts of Windows, randomly moving data and code around in memory to make it harder to exploit.
Mitigations that were once applied to Windows applications are now also applied to the Windows kernel.
The Windows heap, where Windows applications receive their memory from, includes additional checks to defend against exploit techniques.
Internet Explorer 10 includes improvements that make 75% of the security vulnerabilities reported over the last two years more difficult to exploit.

6. New Apps Are Sandboxed

Apps for Windows 8Õs new Modern interface (formerly known as Metro) are sandboxed and restricted in what they can do on your computer.

On the Windows desktop, applications had full access to your system. If you downloaded and ran a Windows game, it could install drivers on your system, read files from everywhere on your hard drive, and install malware on your computer. Even if programs run with limited credentials thanks to UAC, they typically install with Administrator privileges and can do anything they want during installation.

Windows 8 apps function more like web pages and mobile apps on other popular mobile platforms. When you install an app from the Windows Store, that app has limited access to your system. It canÕt run in the background and monitor all your keystrokes, logging your credit card number and online banking passwords like applications on the traditional Windows desktop can. It doesnÕt have access to every file on your system.

Apps for Windows 8Õs new Modern interface are also available only available through the Windows Store, which is more controversial. However, users canÕt install malicious Modern apps from outside the store. TheyÕd have to go through the Windows Store, where Microsoft has the ability to pull them if theyÕre discovered to be malicious.

Windows 8 is definitely more secure than Windows 7. An integrated antivirus and application reputation system, along with a tamed app ecosystem that replaces the wild-west nature of previous versions of Windows, will probably make the most difference for inexperienced users that may not have ran an antivirus or knew which applications were safe to install on previous versions of Windows. Low-level improvements to the way Windows manages memory will help everyone, even power users.

Operational System Differences ‰ÛÒ Linux Windows Chrome Mac OS X

No matter whether we have used or not, we must have heard these four operational systems, Linux, Windows, Chrome and Mac OS X. Maybe there are many opinions or deep understanding about them. So in this passage, I just introduce every operating system simply and make a summarization about differences between operating systems. And express my opinion about how to choose one suitable operational system for oneself.

1st OS: The older operational system Ð Linux

Linux is a free operational system with all of functions included in UNIX. Stable performances, high

efficiency and flexibility make it become popular for almost of computer hobbyist to learn, research, and modify computer operating system kernel. And this is why computer users like to use Linux.

But to be more, Linux is just the kernel. It is still difficult for common computer user to install and run it on computer. Because Linux traditional user interface is command interface based on text. And why it is different to computer hobbyist? There are mainly two reasons.

1. Linux is like free software.

Anyone doesnÕt need to pay for it to get its original code and computer user could modify it according to their purpose. Free use and transfer it freely.

2. Linux includes all of functions of UNIX.

So for people who want to learn UNIX or use UNIX, Linux is the best platform.

Therefore, for computer hobbyist, there are still advantages in Linux.

Openness.
Multi-user and multi-task.
Friendly user interface.
Device independence.
Kinds of Network function.
Safe system security.
Good portability.

Now see the differences between Linux and Windows/OS X:

In development history, Linux is developed from a relatively mature operational system. And Windows is designed newly and independently.
In cost, Linux is free. And Windows and OS X have to be paid for.
In usability, Windows and OS X are friendlier than Linux for common computer users.

2nd OS: Google special operational system Ð Chrome OS

Chrome OS is open operational system based on Linux, designed for netbook. Actually, Chrome OS
is Web operating system. Most of data and files are dealt with on Internet. So how is Chrome OS?

There is no ÒUserÓ in Chrome OS. Google account will be used to login into Chrome OS instead of ÒUserÓ.
Network is needed when you access Chrome OS. Not like Windows, login Windows with user and do work on Windows computer without network are available.
Chrome OS looks like a Chrome browser. No data are saved on local computer. All of them are stored in Cloud. And all of system applications are Web applications.
Because of lack of local file system and desktop, security of Chrome OS is no match for Windows.
Just about few seconds are needed to boot Chrome OS, but about a minute to boot Windows.
Less demand in PC computer power if you use Chrome OS.

Even though there are so many advantages in Chrome OS, some questions are still asked usually. For example, Chrome OS couldnÕt be used when no network is available? Is Chrome OS free? PC users only install Chrome OS? To respond to these problems, Google also says, they will make progress in Wifi, data encryption, access Google Docs offline. But these would take time to achieve.

So if you want to experience how Chrome OS works, install Chrome browser to experience is a good choice.

3rd OS: Most humanized and comfortable operational system - Mac OS X

Mac OS X is designed especially for Mac series products. Based on UNIX, it seems to be simple and full of innovation. Mac OS X is friendly-use and it can be handled once people begin to try to use it.

So now see why we choose Mac OS X?

System interface is beautiful than any other operational systems.
Easy-of-use. Anyone could learn to use Mac OS X instantly. And it is no need to install other third-party software.
More safe. Because of no need of downloading third-party software, netbook is not so dangerous.
More stable.

Generally, it is not necessary to adjust system programs.

But why it is said Mac OS X is not suitable for general computer user?

Mac OS X is special operating system only provided by Apple. It is hard to find one and install it.
Lots of software available for other operational system is not available for OS X, such as games software. So its compatibility is not so good for general computer user.

So we can see the differences between Mac OS X and Windows. Try to understand why Windows is more suitable for common computer users and Mac OS X is not. And there is no doubt that Mac OS X is good operating system actually.

Mac OS X runs faster than Windows.
Mac OS X is more stable than Windows.
Windows is better than OS X in compatibility.
Mac OS X is hard to be poisoned than Windows because its fewer users and less chances to get touch with third-party software.
It is easier to realize double system in Windows computer than Mac.
Mac OS X is more humanized than Windows. But people who use Windows could become computer experts, but not for Mac users.

4th OS: Common operational system ÐWindows

Windows is one operational system which is used widely both for persons or corporations. From the above introduction, we could see, its easy-of-use and compatibility are two main reasons. Now letÕs see the advantages of Windows:

1. Intuitive and efficient object-oriented graphical user interface

Windows user interface is object-oriented. It works with way ÒChoose object Ð Operate objectÓ. For example, we choose document first with keyboard, and then choose ÒOpenÓ button in right-click menu. It imitates behaviors in real life, so it is easy to understand, learn and use.

2. Unified and friendly user interface

Most of Windows programs meet standard of Common User Access. All of these programs have the similar appearance, including window, menu and toolbar. As long as user handles one of them, there would be no problem to use others.

3. Rich and device-independent graphics operations

Windows GDI provides rich graphics operations functions. So we can draw different kinds of graphics and different kinds of output devices are supported.

4. Multi-task

Windows permits user to run different kinds of tasks in the same time. Every program would run in window. Computer user could move these windows to change program running in different time.
