win7瘦身减肥清理篇(国外英文资料) Weight loss clean-up articles The volume of the new Win7 system is a bit scary, and a 2.4G compact system is smaller than 6~7G, and 12~13G (virtual memory, paging files, depending on memory capacity). Is Win7 born so bloated and bulky? No ~ 1, close the virtual memory (Note: if the original memory is only 2G did not upgrade the memory capacity to 4G please do not close, otherwise the system will easily lead to burst memory process and even system collapse) Win7 is the largest file in the hard disk space, and the first one is virtual memory file, or paging file. This file is hidden in the C root directory, file name is pagefile.sys. Virtual memory is XP times some functions, its core essence is through the hard disk space as virtual memory to the program calls for writing, to solve the operating system and the process of memory resources is too large and the contradiction of physical memory capacity. The default size of the virtual memory is automatically adjusted by the system, typically around 2 times the current physical memory capacity. Close the virtual memory, not only can save 3~4G space, but also can significantly improve the system operation speed and greatly reduce the number of disk (hard disk read can prolong the hard life of lower probability of bad sectors). Frankly speaking, virtual memory really can solve the problem of insufficient physical memory, but unfortunately, the hard disk can not be used as memory after all, and it is the bottleneck of the Norman architecture computer. The speed of the hard disk is several orders of magnitude lower than the memory, and the delay is several orders of magnitude higher. Virtual memory is, after all, a palliative. The use of virtual memory is the cost of the program running in the background or to run large-scale 3D games is starting the program, when the operating system, switching to reflect slow even feign death, take a long time to reflect over, especially playing the big game in the occ
