After Microsoft's official XP release, it is estimated that there are quite a few people who install this system. XP's technical articles have also begun to increase, but use XP to be careful about the "taboos" mentioned below. If you don't pay attention, it will make your system unstable or troublesome, but it may damage your hardware. ! First, avoid virtual optical drive Now most virtual optical drives are unstable in XP, it is easy to cause XP's crash, because virtual optical drive is different from general software: it tricks Windows through "device manager" through special mechanism, let Windows thought that the physical drive was added. XP only designed the driver to restore the hardware. I didn't expect to "restore/delete" the hardware itself. Because XP is specially optimized for NTFS and network, and most virtual CD-ROMs are developed under the FAT32 environment. Currently, there are few virtual CD-ROM softwares that are compatible with XP. If you have to install them, you have to endure several crashes. Come slowly and try which one is stable, and XP may crash if you don't. Special reminder is that even if you find a stable virtual CD-ROM software, if you have more than 4 physical CD-ROMs, you may trigger XP's activation verification mechanism, asking you to activate XP again - because Microsoft thinks you changed The four hardware is probably a machine change, so it is recommended that you do not install a virtual CD drive. If you really want to use a virtual optical drive, it is better to use multiple operating systems. It is better to use the 98 inside. It seems that only developers who write virtual CD-ROM software can write a new version that can run stably without causing activation, so that everyone can really use the virtual drive. Second, avoid invalid date XP also has a date inspection mechanism with the activation test. If your motherboard CMOS battery is powered down, or if you misuse or use other date-limited software, causing the date to become an invalid date in 1999 (99 has not yet developed XP), then XP will initialize the graphical interface. After the word "welcome", the system is locked, and there are no prompts and options, just like the crash of the mouse. If you don't pay attention to the effect of the date, no matter what operation you can't fix XP, the author has eaten the loss and reloaded XP. Later, I found out the real reason - so be sure to take care of the date you started XP and enter XP. After that, it is ok to change the date. Third, avoid the power supply of the cat is not open XP is optimized for ISDN and broadband network design, for MODEM is not so "care". Many cats do not have proper drivers in XP. They can only be replaced by FOR 2000 or NT drivers, and dial-up exceptions often occur. Especially a lot of foreign cats, if you do not turn on the power of MODEM when you start XP, you will not find the hardware after entering the graphical interface and then open XP. You need to refresh the scanning hardware or restart XP again in the device manager. Trouble - some people don't know why, don't restart XP, but constantly download different versions of the program update, restore driver may cause the entire system to crash, so friends with foreign cats please pay attention: remember to open you before entering XP MODEM power supply. Fourth, avoid the lack of security knowledge of the novice to open the default sharing and remote assistance XP because it is part of the implementation of Microsoft.Net strategy, the default is to open a lot of network functions. For example, share your drive, remotely solve Windows operation problems through the network, and so on. These network functions may be very convenient for people who know how to do it, but for beginners who don't have enough knowledge about network security, there is a certain danger, because sharing the drive and allowing remote assistance is the need to open the port of your computer and open certain permissions. Although XP has its own firewall, if you encounter a clever virus or a malicious hacker, these services may also expose you to data loss or compromise. People who are not familiar with network security knowledge are advised to turn off the sharing and remote assistance functions if they do not need to access the LAN (you need to turn off the server service in the management tool). Fifth, avoid installing XP and then installing Windows9X in the same partition. XP is developed with NT architecture, but the default directory for placing files is not WINNT. It is also named Windows directory on the partition where you install XP. If you install XP98 in the same partition after installing XP, not only may destroy the boot menu of multiple operating systems, but also because the 98 installer overwrites the file to destroy XP system, because 9X default installation path is also Windows. . Therefore, it is recommended that you still have a separate partition for each operating system, and pay attention to installing a low-level version of the window, and then install XP, so as not to use the installer to repair the multi-boot menu. Six, avoid supporting ACPI on a bad machine with XP standby or hibernation support ACPI is not good on the machine, mainly power and motherboard problems, at this time if you use the sleep or standby function, the sound card may sound after recovery Normal, with a lot of murmurs; in addition, because standby and hibernation are to shut down the hard drive, but in systems with poor ACPI support, the hard drive is turned off but the power is not turned off, or even the hard drive is not completely closed. It may be that after a few seconds, the hard disk is automatically turned on again, so that the magnetic head is greatly affected by the current without being reset in a short time, and the life of the hard disk will be greatly affected. I suggest you find that your XP system standby or hibernation function has a BUG, it is best to change a good power or a good motherboard, if you do not intend to replace, it is best not to use XP standby and hibernation.
