Windows Vista optimization misunderstanding Summary

Many so-called Vista optimization tips. In fact, it is to teach us how to "lose weight" for Vista ". With the increasing popularity of Vista, more and more media have moved these skills to magazines. After such a "package", many friends treat it as a "classic ". But do you know? Many of these so-called optimization tips are misleading. If you blindly follow the rules without thinking about it, it is likely to damage the operating system itself, and thus affect our normal use. Let's take a look at several common mistakes in Vista optimization today.

Misunderstanding 1. The driver Backup directory can be deleted at will

* Misleading index:★★★

* Target path: X: WindowsSystem32DriverStoreFileRepository

If you are a user who often uses Vista, you must have witnessed Vista's powerful hardware support capabilities. It is no exaggeration to say that, if it is not a particularly advanced or unpopular hardware, it will be automatically recognized by the operating system after being connected to Vista, and few users need to manually install the driver. In fact, this achievement is inseparable from Vista's huge driver library of nearly 1.3 GB. As a result, in some tips, "If you have installed the required hardware, you may wish to delete it with confidence, saving 1.3 GB of space ......" Such words.

So is the real situation true? In fact, the problem lies in the phrase "the required hardware has been installed. In fact, although many hardware will issue driver CDs, it is difficult for us to find matching drivers for simple hardware such as USB flash disks. If you have deleted this folder, Vista cannot recognize it when a new USB flash drive is inserted into the system. Even if the so-called "Universal driver" is installed, it will not help.

Misunderstanding 2. regularly clear SuperPrefetch

* Misleading index:★★★★★

* Target path: X: WindowsPrefetch

I believe you are familiar with Prefetch. In the XP era, it is a symbolic function. By automatically recording each running program, XP can speed up its startup through Prefetch at the next startup of the program. However, this technology also has a drawback. That is, as the computer usage grows, the contents in the Prefetch folder will also increase. This not only occupies a large amount of disk space, but also slows down the XP search for pre-read data. Therefore, we recommend that you regularly clear the folder.

However, in Vista, regular clearing of SuperPrefetch is not desirable. Because Vista's SuperPrefetch is undoubtedly more intelligent than XP's Prefetch. In addition to automatically memorizing each running program, it also automatically analyzes startup data. Then, based on the results, when the system is idle, the programs that users may use later are read into the memory in advance to accelerate program startup more effectively. Therefore, once we clear the SuperPrefetch, the startup rules that are hardly counted will be eliminated. Therefore, the best way is to ignore it.

Misunderstanding 3. Deleting WinSxSackup does not matter.

* Misleading index:★★

* Target path: X: WindowsWinSxSackup

Both XP and Vista have a WinSxS folder (Windows Side-by-Side), but they are very different in size. Generally, for a newly installed XP system, the WinSxS folder is about 20 MB. In Vista, its volume will suddenly jump to 3.3 GB. As a result, more and more friends began to study the WinSxS folder. The final "study result" is "you can delete any file in WinSxSBackup ".

In fact, although the volume is different, the WinSxS functions exactly the same in the two operating systems. WinSxS contains many important system files. In fact, the best way to delete such files is not to delete them. Even if a file is lost, a module of the operating system may fail to run, thus affecting our normal use. The same is true for files in WinSxSBackup. When you install the latest system patch, I am afraid it will be difficult.

Misunderstanding 4. UAC is useless to common users. Disable it

* Misleading index:★★★★★

* Target path :-

UAC (User Account Control) is also a newly added feature in Vista. Its biggest function is to grant full permissions regardless of the account currently logged on, will be automatically "downgraded" for normal users. Once the operator (or malware) intends to make changes to the computer, UAC will pop up a dialog box asking the user for approval before the operation. However, the final use effect is not very satisfactory. Many users who are new to Vista will be scared by the pop-up dialog box. Even if you are a veteran and close the window frequently, It is very troublesome. Therefore, many of the optimization tips will disable UAC as a required task.

Although Vista's UAC is somewhat allergic (Vista SP1 has changed a lot), we must admit that it is still a very useful feature. Therefore, disabling UAC alone is not advisable. However, we can adjust the default UAC security level through some small settings. In this way, we can find a balance between system security and ease of operation.

The setting method is simple. You only need to enter "gpedit. msc" in the Start Menu of Vista and press enter to open the Group Policy Editor. Then, expand computer configuration, Windows configuration, security settings, Local Policies, and security options ". In this way, you can find the "User Account Control: Administrator promotion prompt in administrator Approval Mode" item in the right pane. Double-click it, and then change the default "Agree prompt" to "do not prompt, directly promote" from the pop-up dialog box ". In this way, the UAC pop-up frequency is greatly reduced.

Misunderstanding 5. Downloaded Installations is a buffer.

* Misleading index:★★

* Target path: X: WindowsDownloaded Installations

After exploring the directory structure of Vista. Many may assume that a folder named "Downloaded Installations" in the system disk is useless. The only purpose is to back up some software installation programs (mainly software using Windows Installer Installation Technology) Like MSOCache. Therefore, even if the content is deleted, it will not be a serious problem.

The actual situation is that some software (such as Diskeeper or Fireworks 8) will automatically transfer the installation file to the folder except during installation. This file will also be used during uninstallation. If you forcibly Delete the software, the software cannot be uninstalled.

Misunderstanding 6. Forcibly specify the virtual memory size

* Misleading index:★★★★

* Target path :-

Since the XP age, netizens have been circulating such a technique. That is, set the maximum and minimum values of the virtual memory to the same value. In this way, we can ensure that there will not be too many disk fragments. In fact, such a method is not desirable. Because when we set the maximum and minimum values of the virtual memory, it is very large. If a small data file is read, the computer will spend more time searching in the virtual memory. Or, when we set the maximum and minimum values of the virtual memory to an hour. Once the data exceeds the initial page file capacity, a memory overflow error occurs. In this case, the memory consumption is especially serious in Vista systems.

Therefore, the best way is to separate a partition for the virtual memory. Then, set the minimum virtual memory value to 1.5 times the physical memory value, and the maximum value to 3 times the physical memory value.

Misunderstanding 7. Cancel System sleep

* Misleading index:★★★

* Target path :-

In Vista, the sleep function is enabled by default. However, because it is the same size as the physical memory. Therefore, the occupied disk space cannot be underestimated. Therefore, many optimization tips will cancel the system Sleep file and make it a mandatory option. In fact, if you are a laptop user, Vista's powerful sleep and sleep functions not only make you forget the shutdown command. In addition, because it can greatly reduce the disk workload, the notebook will also save more power. In contrast, this hard drive is already an era of cabbage prices. Simply canceling this feature is really undesirable.

Misunderstanding 8. system protection is a chicken fault

* Misleading index:★★★★

* Target path :-

Compared with other new features, Vista's "system protection" takes years. Since its first appearance in Windows Me, it has already exceeded four versions in the Vista era. With the upgrade of the version, the system protection function becomes more and more powerful. Now, in Vista, we can not only restore the system for any period of time (that is, "System Restore "). You can also use files of previous versions to restore files that have been accidentally modified, deleted, or damaged (that is, "Shadow Copy "). It is worth mentioning that, compared with the XP version of "System Restoration", Vista's "system protection" is more stable, and it can completely restore the system to a previous state. The problems of new software installation and registry incompatibility frequently occur in earlier versions of XP have also been well handled. Therefore, disabling "system protection" is definitely not a good idea.

However, it is an indisputable fact. By default, Vista automatically creates a restore point every 24 hours. The system retains 15% of the disk space by default. You know, in this 200 ~ In the 300 GB hard drive era, 15% means that there will be 30 ~ 40 GB space is occupied by "system protection. Therefore, we still need to adjust it.

Conclusion

The mistakes described above. I'm afraid you won't be surprised. As a matter of fact, as long as we keep thinking calmly, we cannot blindly follow others' opinions. Many mistakes can be avoided. For this article, I just want to give you a reminder in the form of a discussion. If you have similar experience in practical applications, share it with you.
