Misunderstanding

in the Windows Vista system optimization process For Vista
this hardware consumption king, I believe everyone has already heard about it. Therefore, many so-called Vista
optimization cheats. In fact, it is to teach us how to "slim" for Vista. And as Vista's attention continues to heat up, more and more media have put these skills into the magazine. After such a "packaging", many friends have regarded it as a "classic". However, some 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. Here are a few common pitfalls in Vista
optimization.
Misunderstanding 1. The driver backup directory can be deleted at will
Target path: X:\\Windows
\\System32\\DriverStore\\FileRepository
If you are a user who frequently uses Vista
, then you I must have witnessed the powerful hardware support capabilities of Vista
. It is no exaggeration to say that if it is not particularly advanced, or particularly unpopular hardware, 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. So, in some "cheats", there is "If you have already installed the required hardware, you can safely delete it, you can save 1.3 GB of space..."
The real situation is really true 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 not recognize it. Even if the so-called "universal driver" is installed, it will not help. So this folder, if you don't know too much about Vista
, don't move it better.
Misunderstanding 2. Regularly empty SuperPrefetch
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. If it is an NTFS partition, you can tick its compression option in the right-click property. If you turn off superfetch, then you can delete it without problems.
Misunderstanding 3. Delete WinSxS\\backup does not matter
Target path: X:\\Windows
\\WinSxS\\backup
Although there is a WinSxS folder in XP and Vista
systems ( Windows
Side-by-Side, but 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. (Although I have not encountered any related problems at the moment)
Misunderstanding 4. UAC is useless to ordinary users, turn it off
UAC (User Account Control) is also a new feature added in Vista
, and Its biggest role 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 close UAC as a must work.
Although the UAC of Vista
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.
Miscellaneous 5. Downloaded Installations and Installer are buffered
Target path: X:\\Windows
\\Downloaded Installations
X:\\Windows
\\Installer (all hidden system folders) )
After exploring the directory structure of Vista
. 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.
And the real situation is that some software (such as Diskeeper or Fireworks 8) will automatically transfer the 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 specify the size of virtual memory
Since the XP era, netizens have been circulating such a technique. 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 noticeable in Vista's memory system, which is quite expensive.
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.
Mystery 7. Cancel System Sleep
In Vista
system, the sleep function is enabled 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, Vista's powerful sleep and sleep features will 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
Compared with other new features, Vista's "system protection" can be described as old. From the first appearance in Windows
Me, to the era of Vista
, 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.
1. Selectively turn on system protection
In contrast, this method is relatively simple, we just click "Start Menu" → "Control Panel" → "System and Maintenance" to open the "System Protection" window Then, remove the check boxes for the partitions that do not need to be protected, and finally click the "OK" button.
2. Adjust the "system protection" disk occupation limit
In addition, we can also limit the disk usage limit of "system protection" by command. For example, to limit to 600MB, first, click the Start menu and find the "Command Prompt". Then right click on the item and select "Open as administrator". At this time, from the pop-up command prompt window, enter the command "vssadmin Resize ShadowStorage /For=C: /On=C: /MaxSize=600MB" (without double quotes). Finally, a prompt will pop up on the screen. And we have successfully completed the setting of the system to protect the disk space occupation limit.
