Windows7 boot memory takes up a large fault resolution

The Windows 7 system has been installed recently, and its interface is very beautiful and more convenient to use. However, I stumbled upon the fact that even after the boot, the program does not run, it will take up more than 900 MB of memory space, open the task manager to view the process, and found no strange process, why is this?

The problem you are experiencing is due to the Windows
XP system that has been used before, which has caused you to make a mindset: because Windows
XP for memory management The ability is not very good, so everyone recognizes that the lower the memory usage of the system, the more memory space can be used to run other programs, and the more memory usage, the slower the system response. And Windows
7 is different, then I will introduce you in detail:

The memory management mechanism adopted by Windows 7 system is called “Superfetch” (ie “super read-ahead” Take ”). In fact, this management mechanism was adopted by Microsoft in the Vista system, but Vista has fewer users and has not attracted attention. Everyone knows that reading data directly from memory is much faster than calling from the hard disk. “Super pre-reading” means that after the system is powered on, the program that the user might use is automatically called to the memory space for preloading. Avoid re-calling from the hard disk every time you open the program, thus speeding up the response of the program.

So, how does Windows 7 know what is “the program that users might use”? This is to talk about the learning function of Windows 7: from the first time you install Windows 7 into the desktop, the system will begin to record the user's usage habits, and the programs that users often use are generally filed. For example, if you open the computer
, you will usually log in to QQ, and open the IE browser. After the system is turned on, the system will call QQ and IE to the memory space. When you use these two programs, it will directly From memory without having to access the hard drive.

Maybe you will ask: If you need to use some large programs, "super pre-read" will take up a lot of memory, will large programs become very slow? This issue is not to be worried. When a user uses a large program, the system automatically transfers these pages to virtual memory without affecting the use of the current program. After exiting the large program, the system automatically re-moves them into memory, which is quite intelligent.

The old experience is very good, but everyone should also adapt to the new features. Only in this way can we “learn faster” and learn more.
