Body
There are two ways to achieve this: <ul> <li>Hook the relevant functions in the kernel - the traditional way - which requires a C/Kernel Driver. This is possible on x86 Windows, but on x64 <a href="http://msdn.microsoft.com/en-us/library/windows/hardware/gg487353.aspx" rel="nofollow">Kernel Patch Protection</a> will detect these modifications and shut down the system (with a bluescreen).</li> <li>Build a <a href="http://msdn.microsoft.com/en-us/library/windows/hardware/ff563911%28v=vs.85%29.aspx" rel="nofollow">registry filter driver</a> - this is the now encouraged way to attack this problem and is the way process monitor works. You can also build file system filter drivers this way. Essentially, you simply need to pass the information back to userland which boils down to: <pre><code>IoRegisterDevice(...somewhere in \Devices\YourDriverName...) IoCreateSymbolicLink(\\DosDevices\Name -> \Devices\YourDriverName) </code></pre> then a C, C++, C# application should be able to open the file <code>\\.\YourDriverName</code> and <code>DeviceIoControl</code> to it and receive responses.</li> </ul> It is possible to use C++ to write kernel drivers, but <a href="http://msdn.microsoft.com/en-us/library/windows/hardware/gg487420.aspx" rel="nofollow">see this before you embark on doing so</a>. To be clearer, you need to be really careful about memory in kernel mode (paged, nonpaged) and you're not going to have access to much of the standard library. As an aside, you should be aware that: <ul> <li>Not all registry hives are accessible to kernel mode drivers, depending on context.</li> <li>The paths are not common. So the kernel accesses <code>\Registry\System</code> whereas userland accesses <code>HKLM</code>.</li> </ul>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
