Some taboos in Windows XP system

First, avoid virtual drive Now most virtual drive is unstable in XP, it is easy to cause XP crash, because virtual drive is different from general software: it through special mechanism, in "Device Manager" I lied to Windows and let Windows think that it has added a physical optical drive. 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. Slowly try which one is stable, and XP may crash if you don't. Special reminder: Even if you find a stable virtual drive software, if you virtualize more than 4 physical drive, it may trigger the XP activation check mechanism, asking you to activate XP&mdash again; — because Microsoft thinks you have changed four hardware It is very likely that the machine has been changed, 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, the date becomes an invalid date in 1999 (no XP has been developed in 1999)
