Windows system pseudo-optimization skills analysis and application

Temptation index: 9 risk index: 8

You only need to prepare two hard drives and a Ghost 2003 Software, you can expand the capacity of the hard disk by a factor of two. Even on some websites, a screenshot of the disk capacity increase under Windows and the detailed process of the above method are given (the specific operation is not described here). This translated article from a foreign website has caused speculation and interest from many netizens. Adding free hard disk capacity is something that everyone is willing to do. The 80GB hard drive suddenly becomes 120GB or more, and everyone wants to eat this free lunch. However, the final test results have caused many netizens to suffer.

On this issue, we specifically consulted Symantec related technical staff. After reading the above method, they said that a new partition generated by this method is definitely not available. If the data is written to the partition, it may damage other normal partitions. The main reason for this phenomenon is that many hard disk partition table files are not certified by Microsoft technology, which causes Ghost to misidentify the hard disk partition in the Windows operating system due to some operation, and generate the hard disk. Misidentification of the partition table. Such a problem is most likely to occur in mirror backup and recovery operations between two different brands of hard drives, but this is a more accidental phenomenon.

Proverbs 2: Svchost.exe is deleted, because it is a virus

Temptation index: 5 Risk index: 7

Shockwave, one appeared in August last year The virus once caused extreme panic to computer users. In 2004, the shock wave was much less, but the shock wave “stunned” did not decrease. According to many reports, many people saw that the system had Svchost.exe process, they said that they were infected with shock waves, and even many people began to think that Svchost.exe is the camouflage shell of Trojans.

But Svchost.exe itself is a normal process in the Windows operating system. It is a program for managing system services in the Windows operating system based on the NT kernel. In Windows 2000, there are generally two such processes; there will definitely be four such processes in Windows XP. In the server-level operating system, the number of Svchost.exe processes is more. Typically, the Svchost.exe file exists under the %Sytemroot \\System 32 directory and under the Dllcache directory. Svchost.exe in other directories may not be normal.

So, in the face of this process, you don't have to talk about it. Don't forcefully delete this file in the correct directory. If you want to identify whether the Svchost.exe method provided by the system is also very simple, just look at the original path of Svchost.exe.

谣言三: Remove 20% of QoS, fast speed up

Temptation Index: 8 Risk Index: 4

After installing Windows XP Professional, run Gpedit. Msc, open the Windows XP Group Policy, and then find the "Computer Configuration → Administrative Templates → Network
→ QoS Packet Scheduler" item, modified to 0%, so you can remove 20% of Windows XP retention Network bandwidth.

This "skill" may be the most widely spread rumor since the advent of Windows XP.

But the problem is really as mentioned above, has Windows XP kept 20% of the bandwidth? The answer is no, the bandwidth reserved is for a new technology introduced in Windows 2000? ? QoS (ie: networked service quality), and, not to say that 20% of the bandwidth will be occupied, in fact, only when using the QoS application programming
interface to write applications need to access the network Will use this 20% of the bandwidth. If these applications that use the QoS API do not have access to the network, the reserved bandwidth can still be used by other applications.

Microsoft specifically addresses this issue in a knowledge base codenamed KB 316666 ( http://support.microsoft.com/
?id=316666). The modified value in the group policy refers to the maximum amount of bandwidth that can be used when the QoS API writer needs to access the network. If we set it to 0%, it means that the application written by the QoS API has to be combined with other The application competes for limited bandwidth, with the potential that data that requires priority communication is not prioritized. Of course, QOS, a new technology that was originally used to improve network quality, has lost its meaning.

Proverbs 4: Change the parameters, add a software, the startup speed will be faster

Temptation index: 6 Risk index: 2

We can often see the so-called Optimize Boot.ini to speed up Windows boot speed: Change Fastdeect at the end of each boot entry to Nodetect. Literally, the quick detection of the startup is changed to no detection, but the biggest problem is that there is no Nodetect parameter in the parameter list in Boot.ini. In the technical information released by Microsoft, from Windows NT to the latest Windows Server. 2003, Nodetect this parameter does not exist, using this fabricated parameter, there may not be a problem, but whether it can speed up the startup speed is still an unknown.

For the Fastdeect parameter, Microsoft gave a detailed explanation: Turn off Ntdetect.com to detect the serial mouse at startup.

But in order to speed up the system startup speed, some people are still infatuated. Coincidentally, Microsoft released a program called Bootvis.exe, and there is a menu under the menu that has an "Optimiae System" option, so there is an optimized startup technique: use Bootvis.exe to speed up Windows XP Startup speed. In fact, Bootvis.exe is a visual performance tracking tool provided by Microsoft to system designers and software developers. Developers can use this tool to track problems that occur during system startup or wake-up. Unfortunately, the tool was used in very inappropriate situations.

Microsoft also mentioned at http://www.microsoft.com/whdc/hwdev...ot/bootvis.mspx
that Bootvis.exe cannot change the startup or wake-up performance of the system. of.
