In 2009, Windows 7 was officially released, because its hardware configuration requirements are not high, became the choice of many mainstream models at that time. According to the latest Netmarketshare report, Windows 7’s market share rose again, with desktop Internet PC users rising to 38.41 percent from 37.19 percent previously. But that was not enough to replace Windows 10, whose global market share fell from 40.90 per cent to 40.3 per cent.
In December 2018, Windows 10 surpassed Windows 7 as the world’s largest desktop system. And, with a squint, ten years have passed.
On July 14, 2009, Windows 7RTM (Build 7600.16385) was officially launched, and on October 22, 2009, Microsoft officially released Windows 7 in the United States, and on October 23, 2009, Microsoft officially released Windows 7 in China.
Windows 7 Mainstream Support Services expires on January 13, 2015 and Extended Support Service expires on January 14, 2020. Windows 7 continues Windows Vista’s Aero 1.0 style and is even better.
Windows 7 is a better-known version of Windows. Although Microsoft has long encouraged users to upgrade to Windows 10, there are still a large number of consumers who refuse to upgrade on the grounds that it is “difficult to use.”
The compatibility and stability of Windows 7 is one of the reasons for its success. Covers 32-bit and 64-bit two versions, taking into account the trend of transition from 32-bit to 64-bit systems.
Windows Server 2008 R2 is only available for 64-bit server systems, but is also compatible with 32-bit programs. The 16-bit window system and MS-DOS applications offer limited support, as in windows Vista x64.
The previous version of Windows 7, Windows Vista, was one of Microsoft’s biggest changes to Windows, laying the foundation for subsequent Windows systems.
However, due to the tight development schedule, Vista had a number of problems after it went public at the end of 2006. Three years later, Windows 7 focused on improving Vista’s problems to save consumers’ hearts with a stable and fluid system.
Windows 7 improves on-screen touch support and handwriting recognition, and virtual hard drives (VHDs) improve the operational efficiency of multi-core (Multi-Core) processors, boot speeds, and core improvements.
The added features include support for multiple graphics cards, a new version of Windows Media Center (12), a desktop gadget for Windows Media Center (WMC), enhanced audio features, built-in XPS, and Windows PowerShell and a new calculator that includes a new model and supports unit conversion.
The taskbar has a large change in appearance. The original Quick Start feature has been replaced by the Shrink program icon on the taskbar.
This feature not only has the ability to quickly boot the original, but also the ability to display the currently running program icons (this is equivalent to the original bar-like program display on the Windows XP and Windows Vista taskbar, just change to icon).
These buttons on the taskbar not only help users run basic program operations such as opening, shrinking to a minimum, putting it to maximum, and closing.
Some of the program’s advanced features or options can also be displayed under the premise of program support (e.g., clicking on Notepad but opening the program while also displaying recently opened files).
The improved taskbar allows users to rearrange the icons on the taskbar.
At the far right of the taskbar (to the right of the system clock), there is a small rectangular button that provides the ability to quickly “show the desktop” (older versions of Windows need to select Show Desktop after right-clicking on the taskbar).
This button is one of Windows 7’s new Aero Perspective features, allowing users to make all forms transparent by simply hovering over them, displaying only the box, so they can quickly navigate through the contents of the desktop.
In addition, because this button is in the lower right corner, so in the touch screen, the button will be relatively large design, so that the user can click.
When you click this button, all windows are reduced, and when you click again, all windows will return to their original size.
In addition, there is a new feature, Aero Snap, that automatically maximizes a window when they move to the edge of the screen/left/right.
This feature facilitates the difference between more and more files at the same time (when moving two or more windows to the edge, the windows are evenly distributed to the entire desktop by size).
This feature can also be run using keyboard shortcuts. In addition, in the improved section of Aero, when a window is maximized, the edge of the window and the taskbar at the bottom will remain transparent (unlike Windows Vista).
Perhaps you haven’t forgotten the global outbreak of the WannaCry worm on the night of May 12, 2017.
According to the BBC, CNN and other media reports, malicious attackers used windows 0day, leaked by the NSA, to carry out more than 75,000 attacks on 99 countries.
This could be another computer poisoning incident following the panda’s burning of incense. At the time of writing, Avast, the anti-virus software maker, reported that at least 75,000 computers were infected. The ransomware virus “WanaCrypt 0r 2.0” has also been found in 99 countries.
At about 20 o’clock last night, some college students in China reported that the computer was attacked by a virus and that the documents were encrypted. The attacker claimed to have to pay for the bitcoin to unlock. However, there are reports that users are still unable to decrypt the data after paying.
According to the Financial Times and the New York Times, the virus issuers used Eternal Blue, a hacking tool for Windows systems designed by the National Security Agency (NSA), which was stolen last year, to upgrade a ransomware virus in February 2017.
Infected Windows users must pay bitcoins for ransom within 7 days, or the computer data will be deleted and cannot be repaired.
As a result of the previous outbreak of the use of 445 port spread worm, operators have been individual users of the 445 port, but the education network does not have this restriction, there are still a large number of exposed 445 port machines.
According to statistics of relevant agencies, the current average daily more than 5000 machines by the NSA “eternal blue” hacker weapons long-range attack, education network is the worst affected by the attack!
As we all know, the 2017 Win10 installed rate is unbearable, most people use win7, of course, there are extreme brother also use XP, this is lazy to what extent.
Since win10 is forced by Microsoft to turn on automatic updates, should have updated the ms17-010 patch, so win10 basic security.
But a large number of win7 (or other lower-version windows) users on the campus network who have turned off automatic updates have become hard hit.
If you do, be prepared to lose those files. According to past experience, paying money does not eliminate disaster.
The file should be encrypted by aes128 (subsequent versions are not known with es256), and under current technical conditions, the vast majority of people around the world do not have the computing power to hack it violently. Want to use violence to save the file can die.
After this incident, some netizens said never to pay, now Bitcoin network backlog of 150,000 transactions unconfirmed, turn hackers also can not receive. Even if you receive the estimate a few days later.
Unlike BITS, 3 seconds to confirm trading, the price is also cheap. So don’t waste money buying bitcoins to support the vicious behavior of hackers.
The bad thing is that, compared to the way most other malicious programs rely on propagation by tricking users into clicking on attachments with attack code, WannaCry can spread itself over the web, much faster than the former.
In order to avoid the effects of this massive spread of virus software in the future, we should get into the habit of backing up important files on a daily basis (although it takes some extra time to deal with anomalies such as data anomalies).
In addition, it is very important to keep an eye on the security updates pushed by Microsoft in the process of using the device.
In this Case for the WannaCry event, if the user installs a patch for the vulnerability in March, there will be no current widespread spread.
Bitcoin is called “coin”, the matter is not currency, similar to Q coin, Taobao currency and other virtual electronic goods, but it is not the same as this type of currency, it does not have a credit subject endorsement, to achieve the full virtualization characteristics.
Whether the sovereign country issued the currency, or electronic coins behind the main issue, Bitcoin is generated by mining algorithm, it can be said that the value of all now quantitative limit, which is a bit like the property of gold, but also less physical wearing value.
Such a clever idea, the genius who invented it but do not want to be known, this is not also also anti-human.
