Misunderstandings when users optimize Vista systems

For Vista, the hardware consumer, I believe that everyone has already heard about it. Therefore, many so-called Vista optimization cheats. In fact, it is to teach us how to "sweet" for Vista. And as everyone's attention to Vista continues to heat up, more and more media have also put these skills into the magazine. After such a "packaging", many friends have regarded it as a "classic". But, do you know? Many of these so-called optimization cheats are misleading. If blindly blinded and not thought about, it is likely to cause damage to the operating system itself, which in turn affects our normal use. So today, I will list a few common misunderstandings in Vista optimization, and let's take a look at it.

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

* Misleading index: ★★★

* Target path: X:/Windows/System32/DriverStore/FileRepository

If you are a regular user of Vista, you must have witnessed Vista's powerful hardware support. It is no exaggeration to say that if it is not particularly advanced, or the hardware that is particularly unpopular, after accessing Vista, it can be automatically recognized by the operating system, and users are rarely required to manually install the driver. In fact, this achievement is inseparable from Vista's huge 1.3-megabyte drive library. Therefore, in some cheats, there is a saying "If you have already installed the required hardware, you can safely delete it, you can save 1.3 GB of space...".

So, is this really the case? In fact, the problem lies in the phrase "The required hardware has been installed." In fact, although many hardware will be equipped with a driver CD, for simple hardware like a USB flash drive, it is still difficult to find a matching driver. If you have actually deleted this folder, then when a new USB drive is inserted into the system, not only Vista will recognize it. Even if the so-called "universal driver" is installed, it will not help.

Misunderstanding 2. Regularly empty SuperPrefetch

* Misleading index: ★★★★★

* Target path: X:/Windows/Prefetch

About Prefetch (pre-reading), I believe everyone is very familiar with it. In the XP era, it was an iconic feature. By automatically recording each running program, XP can speed up its startup with Prefetch the next time the program starts. However, this technology also has a drawback. That is, as the computer usage time increases, the content in the Prefetch folder will also increase. This, in addition, will not only occupy a lot of disk space, but also cause XP to slow down when searching for pre-read data. Therefore, many articles suggest that this folder should be emptied regularly.

However, in Vista, it is not advisable to empty SuperPrefetch on a regular basis. Because, compared with XP's Prefetch, Vista's SuperPrefetch is undoubtedly more intelligent. In addition to automatically remembering each running program, it automatically analyzes the startup data. Then, according to the result, when the system is idle, the program that the user may use later is read into the memory in advance to accelerate the program startup more effectively. Therefore, once we clear the SuperPrefetch, then these rules of startup that are not easily counted are eliminated. Therefore, the best way is to leave it alone.

Misunderstanding 3. It is okay to delete WinSxS/backup

* Misleading index: ★★

* Target path: X:/Windows/WinSxS/backup

Although there is a WinSxS folder (Windows Side-by-Side) on both XP and Vista systems, the volume of the two is quite different. In general, for a newly installed XP system, the WinSxS folder is about 20 MB. In Vista, its volume will suddenly jump to 3.3 GB. Therefore, more and more friends started to research the WinSxS folder. The final "research results" is that "you can arbitrarily delete files in WinSxS/Backup".

In fact, although the volume is different, the WinSxS functions in the two operating systems are exactly the same. As a place to store different versions of system components, WinSxS includes many important files of the system. In fact, the best way for this type of file is to not delete it. Because even if you lose a file, it may cause a certain module of the operating system to be inoperable, which will affect our normal use. The files in WinSxS/Backup are the same, if forced to delete. When you go to install the latest version of the system patch, I am afraid I will run into trouble.

Misunderstanding 4. UAC is useless to ordinary users, turn it off

* Misleading index: ★★★★★

* Target path:-

UAC (User Account Control) is also a new feature added to Vista, and its biggest function is that regardless of the current login account, how much authority, will be automatically "downgraded" for ordinary 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 proceeding. 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, it is very troublesome to close the window frequently. Therefore, many optimization cheats will turn off UAC as a must-do job.

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, simply disabling UAC is not desirable. But we can adjust the default UAC security level with some small settings. In this way, a balance can be found between system security and ease of operation.

The setting method is very simple. Just enter "gpedit.msc" in the Vista start menu and press Enter to open the Group Policy Editor. Then, expand Computer Configuration /Windows Configuration /Security Settings /Local Policies /Security Options. In this way, you can find the "User Account Control: Administrator's Promotional Prompt Behavior in Administrator Approval Mode" item from the right pane. Double-click, and from the pop-up dialog box, change the default "Agreement Prompt" to "Do not prompt, directly promote". In this way, the UAC pop-up frequency is greatly reduced.

Misunderstanding 5. Downloaded Installations is buffering

* Misleading index: ★★

* Target path: X:/Windows/Downloaded Installations

After some exploration of Vista's directory structure. Many friends take it for granted that a folder named "Downloaded Installations" on the system disk is of little use. The only use is to back up some software installers (mainly software using Windows Installer installation technology), just like MSOCache. Therefore, even if you delete the contents, it will not be a big problem.

The reality is that some software (such as Diskeeper or Fireworks 8) automatically transfers installation files to this folder, except during installation. This file will also be used when uninstalling. And if you force them to be deleted, the result is that the software cannot be uninstalled properly.

Misunderstanding 6. Forcibly specifying virtual memory size

* Misleading index: ★★★★

* Target path:-

Since the XP era, netizens have been circulating such a skill. That is to set the maximum and minimum values ​​of virtual memory to the same. This will ensure that there will not be too much disk fragmentation. In fact, such an approach is not desirable. Because, when we set the maximum and minimum values ​​of virtual memory, it is very large. If you happen to read a small data file, then the computer will spend more time on virtual memory for retrieval. Or, when we set the maximum and minimum values ​​of virtual memory, it is very small. Once the data exceeds the capacity of the initial page file, a memory overrun error occurs. This situation is particularly evident in Vista systems where memory consumption is quite severe.

Therefore, the best way is to be able to draw a partition for virtual memory alone. Then, the minimum value of the virtual memory is set to 1.5 times the physical memory, and the maximum value is set to 3 times the physical memory.

Misunderstanding 7. Cancel system hibernation

* Misleading index: ★★★

* Target path:-

In Vista system, hibernation function is Started by default. However, because of its size and physical memory is exactly the same. Therefore, from a practical point of view, the disk space it occupies cannot be underestimated. Therefore, many optimization cheats will cancel the system hibernation file and make a mandatory option. In fact, if you are a notebook user, the 250 blog (http://www.im250.com.cn) reminds everyone that Vista's powerful sleep function and sleep function can not only let you forget the shutdown command. Moreover, notebooks are also more power efficient because they can significantly reduce disk workload. In contrast, in this era of hard drive is the price of cabbage, it is not advisable to cancel this function blindly.

Misunderstanding 8. System protection is a chicken rib function

* Misleading index: ★★★★

* Target path: -

and other new Compared to the features, Vista's "system protection" can be described as old. From the first appearance in Windows Me, to the Vista era, it has spanned four versions. With the upgrade of the version, the system protection function is more and more powerful. Today, in Vista, we can not only restore the system for any period of time (ie "system restore"). Also, you can use previous versions of files to restore files that were accidentally modified, deleted, or corrupted (that is, "shadow copies"). What's more worth mentioning is that Vista's "system protection" is more stable than the XP version of "system restore", which can completely restore the system to a previous state. The old installation software and registry incompatibility problems that often appear in the old version of XP have also been well handled. Therefore, turning off "system protection" is definitely not a good idea.

However, an indisputable fact is. By default, Vista automatically creates a restore point every 24 hours. The system is this feature, leaving 15% of the disk space by default. You should know that in the era of 200-300 GB hard drives, 15% means that 30-40 GB of space will be occupied by "system protection." Therefore, we still need to make some adjustments to it.

Written in the last

These misunderstandings are described above. I am afraid you will not see it. In fact, as long as we keep our usual calm thinking, we don't easily blindly follow other people's opinions. Then, many of these misunderstandings can be avoided. For the purpose of this article, I just want to make a reminder for everyone by throwing bricks and jade. If you have similar experience in the actual application, you may wish to share it with everyone.
