windows 7 debug symbols 不含win7 sp1的symbol
If you plan to install symbols manually, it is crucial that you remember this basic rule: the symbol files on the host computer are required to match the version of Windows installed on the target computer. If you are planning to do a kernel mode debug of a Windows XP target from a Windows
2000 host, you need to install the Windows XP symbol files on the Windows 2000 system. If you plan to perform user-mode debugging on the same computer as the target application, then install the symbol files that match the version of Windows running on that system. If you are analyzing a memory dump file, then the version of symbol files needed on the debug computer are those that match the version of the operating system that produced the dump file, not necessarily those matching the version of the operating system on the machine running the debug session.
