SqlServer2008的卸载 与重新安装

最近在学习一个产品Guidewire,配置这个ClaimCenter6.0产品的数据库使用的是SqlServer2008版本的,这个安装配置倒是没有什么问题的;
但是配置ClaimCenter7.0产品的数据库时,问题就来了,之前安装的SqlServer2008的版本太低了,不支持,由于SqlServer2008 R2版本跟SqlServer2008版本实例不同,
所以先要把SqlServer2008卸载掉,再重新安装SqlServer2008R2版本的;在卸载SqlServer2008的时候可是费了我不少时间啊,当时就是一直不能够完全的卸载,使用Windows自带的“添加/删除”工具,有些就是无法删掉,
查了很多的资料,最终找到了解决方案:
1)使用工具软件“Windows Install Clean Up” 来完成SqlServer2008的完全卸载工作,这个工具确实很方便,能够卸载掉“添加/删除”工具中无法卸载的软件;
2)卸载完SqlServer2008的组件之后,要将安装目录下的SqlServer的目录结构删掉;
3)最后腰删除注册表中的信息;
A:删除HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server
B:删除HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer
C:进入HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and delete all the sub-keys referencing SQL Server.
D:Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and delete all the keys referencing SQL Server.
这样SqlServer2008可以算是完全的卸载成功了,接下来可以放心的安装SqlServer2008R2的实例了。
