The rumor arose because of the need. But it may be too much to have, and some rumors are getting more and more true and spreading. The network developed, what kind of information have, direct translation, their own compilation and modification, their own inventions ... Recently, on the internet, even in some media has let a lot of rumors so that some computer beginners into a deep misunderstanding, and even into the lost. Now, the use of computer "rumors" generally come from some optimization systems, free to enhance system performance and other skills. However, after more use of the discovery, some skills seem useful, but it does not feel what effect, some even cause your system "death."

One of the rumors: Magical Ghost, hard disk capacity will double

Temptation Index: 9 Risk Index: 8

You only need to prepare two hard drives and a Ghost2003 software, you can multiply the size of the hard disk. Even on some Web sites, a screenshot of the disk capacity under Windows and a detailed flow of the above methods are also given (the specific operation is not described here). This article from the foreign website translation article, has aroused many netizen's speculation and the interest. Free up the hard drive This is what everyone would like to do, 80GB hard drive suddenly become 120GB or more, who want to eat this free lunch. But the results of the final Test so many netizens have suffered.

On this issue, we specifically consulted Symantec (SYMANTEC) related technical personnel. They looked at the above method, indicating that a new partition resulting from this practice was definitely not available, and that writing data to that partition might damage other normal partitions. The main reason for this phenomenon is that many hard disk partition table files have not been certified by Microsoft technology, which leads to ghost may be mistaken for the hard disk partition in Windows operating system because of some operation. Such problems are most likely to occur on mirrored backup and restore operations between two different branded hard disks, but this is a more casual phenomenon.

Rumor bis: There are Svchost.exe to delete, because it is a virus

Temptation Index: 5 Risk Index: 7

The shock wave, a virus that emerged last August, has caused extreme panic among computer users. Into the 2004, the shock wave is much less, but the shock wave "fright" has not diminished. According to many reports, many people see the system has Svchost.exe process, said they infected with the shock wave, and even many people began to think that Svchost.exe is a Trojan horse camouflage shell.

But Svchost.exe itself is a normal process in the Windows operating system. It is a program that manages system services in a Windows operating system based on the NT kernel. In Windows2000, there are generally two processes; There will certainly be four of these processes in Windows XP. Server-level operating system, the number of Svchost.exe processes is greater. Typically, Svchost.exe files exist under the%sytemroot\system32 directory and the Dllcache directory. It may not be normal for other directories to appear Svchost.exe.

Therefore, the face of this process can not be pale. Do not forcibly delete this file in the correct directory. If you want to identify the system is not provided by the Svchost.exe method is also very simple, only need to see the original path Svchost.exe.

Rumor three: Get rid of QoS 20%, speed up quickly

Temptation Index: 8 Risk Index: 4

After you install Windows xpprofessional, run gpedit.msc, open the Group Policy for Windows XP, and then locate the computer configuration → administrative Templates → network →qos Packet Scheduler, modified to 0%, This will unlock 20% of the network bandwidth that Windows XP retains. This "trick" may be the most widely circulated rumor since Windows XP was published.

But is it true that Windows XP retains 20% of its bandwidth? The answer is no, the reserved bandwidth is used for a new technology introduced in Windows2000--qos (that is, the quality of networked services), and, not to say that 20% of the bandwidth is bound to be occupied, In fact, this 20% bandwidth is used only when writing applications that use the QoS application programming interface to access the network. If these QOSAPI applications do not have access to the network, the reserved bandwidth can still be used by other applications.

Microsoft specifically addresses this issue in detail in the KB 316666 (http://support.microsoft.com/?id=316666) Knowledge Base. The value modified in Group Policy refers to the maximum amount of bandwidth that can be used when the QOSAPI program needs to access the network, and if we set it to 0%, it means that applications written using QOSAPI have to compete for limited bandwidth with other applications, The likely consequence is that data requiring priority communication is not given priority. Of course, QoS, the new technology used to improve the quality of the network, has lost its meaning.

Rumor four: Change the parameters, add a software, start faster

Temptation Index: 6 Risk Index: 2

We can often see the so-called Boot.ini optimization to speed up the Windows startup measures: The end of each of the Fastdeect modified to Nodetect. Literally, is to change the fast start detection to not detect, But the biggest problem is boot.ini inside the parameter list does not have nodetect this parameter, in Microsoft's published technical data, from NT to the latest Windowsserver2003,nodetect This parameter does not exist, use this apocryphal argument, may not appear to ask , but it is still an unknown whether you can speed up the speed of startup.

For fastdeect This parameter, Microsoft has given the detailed explanation: turns off the Ntdetect.com to the serial mouse when starts the detection.

But in order to speed up the system to start, some people are still infatuated. Coincidentally, Microsoft has released a program called Bootvis.exe, and there is a menu with a "optimiaesystem" option, so there is a technique for optimizing startup: Using Bootvis.exe can speed up the startup of Windows XP. In fact, Bootvis.exe is a visual performance tracking tool that Microsoft provides to system designers and software developers, and developers can use this tool to track problems that occur when the system starts or wakes up. Unfortunately, the tool was used in a very inappropriate situation.

Microsoft also mentioned in http://www.microsoft.com/whdc/hwdev...ot/bootvis.mspx that Bootvis.exe can not change the system's startup or wake-up performance.

Bianhouyu: Because space is limited, we can't make all the "rumors" one by one clear this time. However, from the above example, it can be seen that the current rumors are almost hidden in the seemingly correct operation or theory, or hearsay, and ignore the deeper meaning. Now, what we need to do is to learn as much as possible about the use of a technology. Understanding is not difficult, see the system with the help of the general can be known. For a slightly higher level of users, can use the various materials provided by vendors to obtain detailed information.

It's not scary to run into rumors, it's scary to recognize rumors. So, here we want all readers to have more knowledge to avoid more serious problems caused by misunderstanding.
