Getting Started With Windiff in Windows 7
The Windiff, which you get from a Microsoft Server support CD works perfectly in Windows 7.
While Windiff is straightforward to get working, nevertheless, it leaves me with
a lingering feeling that I have never quite reach the bottom of its capabilities. For example, I rarely use Windiff for copying files.
Let us start with Windiff's principal job, namely comparing files. When you launch Windiff, take careful note of a pair of almost identical menus. Go slowly. Be alert for Windows 7 Windiff to ask you for the names of the two files in quick succession. I emphasise this because when I was a greenhorn, I thought either I was going mad, or Windiff had a bug. My salvation was reading the screen, Select First File, then Select Second File - it really is that easy to get started.
Once you have loaded the two files into Windows 7's Windiff GUI, I expect you want Windiff to identify the differences. The trick is to click on 1 .\filename and then click on Expand. (See screenshot opposite.)
As ever, Microsoft provide two ways of doing everything, so you could click on the Expand Menu and then select, 'Both files'.
Once called to action, Windiff homes in on every minute difference between the two files as you would want. Moreover, for easy reading, it highlights each difference with a different color. The color coding extends into the margin so you can see which file corresponds to the yellow highlight and which to the red highlight.
If the content is the same in both files it only has one entry, which you see in normal black text. Where there are differences, not only do you have the exceptions highlighted, but it gives you the line number.
The screen shot is taken from a regedit export. As I mentioned earlier, one of my classic uses of Windiff is researching where in the registry Microsoft store particular settings.
SolarWinds' Orion performance monitor will help you discover what's happening on your network. This utility will also guide you through troubleshooting; the dashboard will indicate whether the root cause is a broken link, faulty equipment or resource overload.
Perhaps the NPM's best feature is the way it suggests solutions to network problems. Its second best feature is the ability to monitor the health of individual VMware virtual machines. If you are interested in troubleshooting, and creating network maps, then I recommend that you try NPM now.
After doing its best to match the files line-by-line, Windiff looks at the remaining parts. Where there are sections which are different, but which correspond, in the sense that the part before and the part after match, Windiff has a choice between displaying the lines as blocks or as interleaved.
Windiff uses a heuristic intelligence to decide whether the lines from the two files are similar. If it judges that they are similar it displays them interleaved, otherwise it displays them as blocks.
Windows 7 Windiff Compare Folders or Directories
A secondary job for Windiff is to compare whole folders or directories. Just click on the File menu and select 'Select Directories'. This time you see both directories one under the other so there is no chance of confusion.
Press F8 to see the next change / difference.
Windows 7 Windiff Options
Although there is nothing really exciting in the Options menu, they are worth checking. For example, if you remove the tick next to: 'Show Identical Lines, it will help you track a single change in large files. In addition to the options, check out the Expand menu and decide whether you need to add or remove any of those options.
Windiff's Mark Menu
It is easy to overlook the Mark menu. The job of this menu is to hide or exclude files in your search.
Windiff Command Line Options
My old friend 'Barking' Eddie insisted that I added this command line section. As I may have mentioned in previous Eddie is an ex-UNIX man and is a founder of 'Dos Diehards'.
Windiff Command Line Options:
This freeware monitor is great for checking whether your network's load-balancing is performing as expected, for example, are two interfaces are getting about equal traffic?

Not many people realize the benefits of comparing registry settings with Microsoft's Windiff. However, like the all the best ideas, once you understand the idea the concept becomes blindingly obvious.
Let us take scenario where we want to find a particular value in the registry, for example, a setting on the Winlogon message box that we wish to control. Here is the outline of our plan:
