Windows 2003在安装sp2补丁时出现：Windows Server 2003 Service Pack 2 无法安装，用来安装 Microsoft Windows 的产品密钥可能无效。有关接收到此错误消息的原因和如何解决此问题的更多消息，请访问 XXXXX。

解决方法：

1、新建一个记事本；

2、将以下代码拷贝到其中

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion]
"ProductId"="69713-640-9722366-45198"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion]
"CurrentBuild"="1.511.1 () (Obsolete data - do not use)"
"InstallDate"=dword:3f6c976d

"CurrentType"="Uniprocessor Free"
"ProductId"="69713-640-9722366-45198"
"DigitalProductId"=hex:a4,00,00,00,03,00,00,00,36,39,37,31,33,2d,36,34,30,2d,\
39,37,32,32,33,36,36,2d,34,35,31,39,38,00,5a,00,00,00,41,32,32,2d,30,30,30,\
30,31,00,00,00,00,00,00,00,00,e5,3f,e9,6a,2c,ed,25,35,12,ec,11,c9,8d,01,00,\
00,00,00,00,37,03,6d,3f,44,22,06,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\
00,00,00,00,00,00,00,00,00,00,00,31,32,32,32,30,00,00,00,00,00,00,00,dc,0f,\
00,00,bf,4a,94,6c,80,00,00,00,15,18,00,00,00,00,00,00,00,00,00,00,00,00,00,\
00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,34,79,ca,d7

25,20,0e,80,83,80,1f,31,27,86,64,1f,31,dc,22,af,f7,7d,aa,e4,2a,b9,e5,e3,6c,\
e2,01,69,85,70,91,be,a7,9f,95,e5

3、重命名记事本文件为 “SP2补丁.reg” 即注册表文件；

4、然后双击运行它就自动导入到了注册表中，这次在安装SP2 就没有任何问题了 。

PS：如果安装了杀毒软件最好先禁用监视，它会拒绝补丁访问。使得补丁被迫停止.
