Most users are very familiar with win7, but will they operate correctly? What are the operating errors of win7 system? I share the misunderstanding of win7 system operation, hoping to help you.
Analysis on the misunderstanding of win7 system operation
1. Can periodic emptying of superprefetch really speed up?
Misunderstanding 1 Empty superprefetch periodically
This secret script should have been handed down from the XP era. It is undeniable that prefetch in XP is not easy to use, and the effect is usually a little wrong. Therefore, someone thought about emptying this folder to solve this problem. However, with Microsoft's attention to this issue and the continuous improvement of Vista and win7 versions, today's prefetch (which has been upgraded to super prefetch) is quite easy to use. It can not only automatically remember program files, but also record data cycles.
For example, if we usually start word directly after turning on the computer, superprefetch will automatically pre read word files after starting, and use initiative analysis to cater to user habits, which will naturally greatly improve the efficiency. Therefore, when we empty the superprefetch file, these long-term accumulated startup rules will be eliminated. Instead of helping the program startup, it will cause windows to re record these rules. Therefore, leaving it alone is the best optimization.
Misunderstanding 2 Modify the boot settings to speed up
This "skill" comes from the translation of an overseas article, that is, set the "number of processors" in "system configurator (msconfig) → boot → advanced options" to "2", and check the "maximum memory" check box to improve the startup speed of win7. I don't know how this article passed the review at the beginning. In fact, no one found that the startup speed would be improved after such a setting, whether it was the author himself or asking colleagues around. On the contrary, some system crashes occurred to individuals.
After querying the Microsoft library, the author found that this setting is only used by maintenance personnel to debug the system, which belongs to the operating system compatibility option. For example, when the system has a startup failure, the maintainer can use this option to forcibly close a core (or part of memory) to judge whether the startup failure is caused by CPU and memory hardware defects. By default, if this option is not checked, Windows 7 starts according to the nominal core of CPU (i.e. 2 core), and there is no conclusion that it can be accelerated after setting.
Misunderstanding 3 2G memory to disable virtual memory
A secret has been circulating on the Internet. If your memory exceeds 2GB, you can disable virtual memory to avoid large-scale data exchange in low-speed hard disks, thus reducing the overall performance of the system. However, careful netizens should have noticed that this skill has a long history and should accurately belong to the product of the XP era. As we all know, compared with the previous WinXP, vista and win7 occupy more memory. Perhaps 2G of memory is enough for an XP computer, but it is just normal for win7.
If you really follow the "skill", after disabling virtual memory, you will not find a significant improvement in system performance, but will lead to more errors. The reason for this is that win7's grasp of hardware performance is far better than vista. If your configuration is not very bad, whether you disable virtual memory or not will not have a significant impact on the execution efficiency of the system. But during this period, we ran a super large program (such as XX game), and when the remaining memory can no longer meet the needs of the system, what is waiting for you is either an error or a complete system crash. Therefore, it is not advisable to disable virtual memory in win7 system!
Shouldn't 2win7 set virtual memory?
Misunderstanding 4 Virtual memory should be set to 1.5 times physical memory
This technique should be more familiar to many old birds. Its origin is probably in the Win9x era. That is, setting the virtual memory to 1.5 ~ 3 times of the physical memory is the most scientific setting method. However, you may have overlooked a small problem, that is, when this technique was popular, the computer memory was still hovering between 32MB and 128MB. To tell the truth, it was very NB that which computer could afford a PC133 256MB memory in those years. With such a small physical memory, the utilization rate of virtual memory is very high. Therefore, referring to the above settings, virtual memory can indeed achieve a certain effect, which is often referred to as reducing the "memory bump rate".
However, with the rapid development of hardware performance, we have already entered the GB era. Now open the computer configuration list, 2GB and 4GB memory have already become standard configuration. If the above "specifications" are to be followed, the virtual memory will undoubtedly be set to 4GB ~ 12gb. Not to mention whether software really needs such a large exchange space, even if there is a mainstream SATA2 interface hard disk (its data reading speed is about 100MB / s), it takes about 40 seconds to fully read the virtual memory (calculated by 4GB). Moreover, frequent reading and writing will inevitably lead to "hard disk fragments", so it is strange that the computer is not slow.
After talking for a long time, how much virtual memory should be set? The author believes that due to the large span of current computer configuration, it is not appropriate to simply limit one standard. The best way is to adjust it through win7 itself. Don't underestimate it. Therefore, the method tailored according to the configuration of win7 can not only minimize the loss of hard disk space caused by system operation, but also expand intelligently according to the application situation (that is, win7 will automatically expand the virtual memory when temporarily running some large programs), which is often more reliable than a fixed size you racked your brains to come up with.
Note: similarly, do not set the initial value and maximum value of virtual memory to be the same. Although in theory, this practice can reduce the generation of some hard disk fragments, it often leads to some irregular errors in the system, which makes the system run more unstable.
Misunderstanding 5 System protection is chicken ribs
Many netizens will turn off the system protection at the beginning of installation. They think that this function does not have much use except occupying certain resources in vain. In fact, this reason may be traced back to the windows me system in 2000. That year, Microsoft added "system restore" in Windows me for the first time, hoping to help users reduce the difficulty of system maintenance through this function. However, due to poor design and windows me itself, this function has been criticized by many netizens.
However, with the improvement of the operating system, the "system protection" in win7 era has already solved various problems before. It can not only protect the system settings, but also restore the file versions at different times (i.e. "historical versions"). Most importantly, win7 allows users to freely set the disk space occupied by the system protection. Once the backup exceeds the limit, win7 will automatically delete the old restore point and make room for the new restore point. The operation is very humanized.
Misunderstanding 6 System slimming with wood
Many secrets are warning users that the system should be cleaned from time to time. Even for convenience, some one click cleaning tools have been specially circulated on the network. It is undeniable that regular system cleaning can indeed improve performance, but the author would like to emphasize here that the concept of "garbage" is relatively broad. Some files may be useless to you, but it does not mean that others are useless. For example, the author once found winsxs and msocache folders in some cleaning tools. In fact, although these two folders are huge, they are by no means useless.
The former contains some important files of win7. Once deleted by mistake, it is likely to lead to system crash, while the latter is the "local installation source" of office software (actually the backup of office CD on hard disk). Although deleting it has no impact on daily use in a short time, it will lead to failure once users intend to carry out special operations (such as adding and deleting components, installing SP package and repairing Office), Finally, there is only one way to unload and reinstall. Therefore, you must clean the system according to your own situation. If you are not sure, don't click it!
3win7 system slimming is really good for win7?
Misunderstanding 7 Install a file and you can get 4GB of memory
Nowadays, the price of memory is low, and many players directly go to 4GB memory at the beginning of installation. However, a very embarrassing reality is that 32-bit win7 cannot recognize 4GB of memory, up to 3.25gb. In order to solve the confusion of large memory users, some methods to enable 32-bit systems to support 4GB by "lifting" began to spread on the Internet. However, it was later proved that some software only changed the system display, and the real memory was not utilized, but affected the stability of the system.
So if you really have 4GB of memory, you'd better change to 64 bit win7. After all, the 64 bit system has good compatibility. If you are still attached to the old version of the 32-bit system, the author suggests that you might as well search the program ramdisk. Its brilliance is that it can directly virtualize part of the idle memory into a hard disk. With the help of this high-performance "hard disk", we can not only place the virtual memory (pagefile), but also move the temporary folder (Temp) or ie cache (temporary). With the help of the high-speed area of the memory module, we can enjoy an unparalleled performance experience. Maybe it's more valuable than trying to add a 0.75GB memory space.
Misunderstanding 8 UAC is useless
Many people don't like UAC, because this function often pops up a dialog box from time to time, which is boring. In fact, this is because you don't understand the principle of UAC. Unlike the XP system of that year, vista and win7 naturally do not have administrator permissions. All operations that affect the system (such as software installation, system adjustment, etc.) need higher-level administrator authorization. If a program is not authorized, it will never start. Therefore, when a large number of software are installed (for example, when the system is just installed), it is not difficult to understand why UAC frequently pops up dialog boxes.
But on both sides, although UAC is really annoying, it is really useful. For example, when we visit a hanging horse website, the Trojan invasion is ready to start, and UAC will also send us a reminder. Therefore, even if users do not install anti-virus software, they can find these guys running secretly for the first time. In fact, in order to optimize the four levels of UAC, it has also greatly reduced the interference between users and winc.
Can 4win7 acceleration and Aero effects not coexist?
Misunderstanding 9 To play acceleration, you have to go to special effects
Many secrets tell you that if you want the computer to run fast, you have to turn off all kinds of gorgeous special effects. At first glance, this sentence seems very reasonable. After all, computers are used for use. Whether they are beautiful or not naturally comes second. However, as we know, compared with the previous version, win7 not only introduces a more gorgeous appearance, but also adds many innovative humanized functions, such as Aero Peek, jumplist, taskbar thumbnail, taskbar progress display, etc., which all rely on the new aero special effects. These features not only bring us a refreshing feeling, but also make it much more convenient for daily use. If you abandon these new features just for speed, it's a bit of a waste of food because of choking. If so, why not install Win98 for fun.
In fact, there are many ways to speed up the system. Compared with turning off Aero effects, the author prefers to streamline the system services. Generally speaking, as long as you are careful when optimizing and don't hurt important services (through some optimization tools), the speed-up effect it brings is no less than that of closing special effects.
Misunderstanding 10 Deleting sleep is awesome.
If you want to say the file header in win7, you can count it in addition to virtual memory. This is a file hidden in the root directory of the system disk. The file name is hiberfil Sys is used to write the data in the physical memory into the sleep file in turn when the system is asleep, so that it can be directly restored to the sleep state when it is restored next time. Because of the limitation of the principle of this technology, its size is exactly the same as the physical memory (that is, if your computer has 2GB of memory, hiberfil.sys is also 2GB), which looks very huge. But for today's computers, deleting a few GB file actually has no impact on the system speed, but will make you lose the fun of enjoying win7 hibernation.
Compared with desktop users, notebook users may be more aware of the benefits of sleep. When we close the cover of the notebook or press the power button directly, we can activate the sleep operation (or sleep). Compared with the traditional shutdown operation, the recovery of sleep (or sleep) is not only faster, but also can be directly restored to the appearance before sleep. For example, when we were editing a word file, win7 will also place the file on the screen after recovery, so that people can enter the working state quickly. At the same time, less reading and writing operations (especially sleep) will greatly prolong the actual life of the hard disk.
Note: sleep and hibernation are both ways of win7 hibernation. The difference is that sleep is suitable for leaving the computer for a short time. All files and states will be automatically retained in the memory, and the speed of sleep and recovery is fast. Hibernation is to store all the above data in the hard disk file (hiberfil. Sys), so the speed is slightly slower than sleep. It is worth mentioning that sleep can be automatically converted to sleep after a period of time (settable) to save system power.
Write at the end
Since Win9x a long time ago, system optimization has been a very hot topic. Many posts on how to optimize computers can be found on the Internet. Optimization always varies from person to person. Blindly pursuing the wind without knowing it is likely to be counterproductive. In fact, the authors of many optimization posts are in this situation. On the one hand, they teach people how to optimize the system (when what they say is right), on the other hand, they rarely tell the actual disadvantages of this optimization. They call it can improve the system speed, but in fact, they increase the hidden dangers of the system and lose the opportunity to experience the new features of windows.
Therefore, this may explain why some people are fine when installing an anti-virus software, while others are often poisoned, because good security awareness and habits are the ultimate core to ensure system security. At this point, there is no difference between system optimization and system security!
