First, upgrade on the basis of SP2 low version

Under normal circumstances, SP2 upgrade installation package can be successfully installed to the computer with WindowsXP operating system and SP1 patch package installed in. However, suppose you have upgraded your computer to SP2, and then want to upgrade the SP2 version based on this, such as SP2_2135, SP2_2144, SP2_2149 and other upgrades based on the SP2_2096 upgrade. The system will prompt you that the SP2 operating system is installed on your computer and cannot be upgraded again. The solution is to modify the registry: delete the "CSDBuildNumber" and "CSDVersion" under HKEY_LOCAL_MacHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion, and then you can install it normally.

Second, cross-installation between Simplified Chinese and English versions

Under normal circumstances, SP2 upgrade installation package can only be upgraded and installed on the basis of their respective language versions. That is, the Simplified Chinese upgrade package can only be installed on the lower version of the Simplified Chinese version of the operating system, while the English version can only be installed on the lower version of the English version of the operating system. The solution is to modify the registry. Install the SP2 English version upgrade package based on the Simplified Chinese version: expand the registry [HKEY_LOCAL_MacHINE\\SYSTEM\\ControlSet001\\ Control\\Nls\\Language] branch, find the string values ​​"Default" and "InstallLanguage" in the right window, double click respectively They change their value data from "0804" to "0409" in the pop-up edit dialog; otherwise, if you want to install the SP2 Simplified Chinese upgrade package on the English version, just put the same string value from " 0409" can be modified to "0804".
