基于WMI的信息查询和编辑,按微软的说明一般都是
Requirements
Minimum supported client  Windows Vista
Minimum supported server  Windows Server 2008
Namespace  RootCIMV2
MOF  CIMWin32.mof
DLL  CIMWin32.dll

操作系统能读到的信息,都能读到.内容丰富的撑到爆.在windows域环境下,wmi是可以查看域内任意计算机信息的,不限于本机,当然需要你有相应域权限.
具体可msdn.microsoft.com搜索
比如磁盘的:
https://msdn.microsoft.com/en-us/library/aa394132%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396
操作系统的:
https://msdn.microsoft.com/en-us/library/dn792258(v=vs.85).aspx
基本上windows整个体系方方面面统统可以用此方法读取和操作.这也是微软未来的方向,以前的单个api系统会慢慢被wmi统一掉.
当然XP对很多wmi不支持,Windows Vista 则几乎都没问题
