注册表编辑器是^{(Registry Editor)}Windows操作系统的一个相当敏感的部分，使用它时应始终小心，因为一个错误的更改可能会使您的系统崩溃 。不需要的注册表更改甚至可能会损害您的用户体验。有时您甚至可能需要监视和比较程序对注册表^(Registry)所做的更改。

我们已经了解了如何 使用Process Monitor、RegShot、 WhatChanged 或内置 fc.exe 工具来监控注册表更改。^{(monitor registry changes)}现在让我们看看如何使用RegFromApp来跟踪、捕获和比较程序所做的注册表项更改。

^{(Compare Registry)}比较程序所做的注册表更改

^(RegFromApp)Nirsoft的^(Nirsoft)RegFromApp是一款可用于 Windows x64 和 x86 机器的免费便携式软件。下载后，打开RegFromApp。

在这里，您可以找到几乎所有已安装在计算机上的程序。选择一个并点击OK按钮。

之后，每当所选程序进行任何更改时，它将像这样存储：

RegFromApp没有复杂的设置。但是，您可以更改显示模式^{(Display Mode)}。有两种不同的显示模式，即Show Last Modified Values和Show Original Values。

您应该记住的一件事是，如果您想监视 32 位程序的注册表更改，则必须下载 32 位版本的RegFromApp。例如，如果您使用的是 64 位版本的Windows，但您安装了 32 位版本的Google Chrome。那么您将无法使用 64 位工具来监控您的 32 位Chrome。

Track, capture & compare Registry changes made by Program

The Registry Editor is quite a sensitive part of the Windows operating system, and one should always take care when using it, as a single wrong change can crash your system. Unwanted registry changes may even hurt your user experience. At times you may even need to monitor and compare the changes made to the Registry by a program.

We have already seen how to monitor registry changes using Process Monitor, RegShot, WhatChanged or the built-in fc.exe tool. Now let us see how to use RegFromApp to track, capture & compare registry key changes made by a program.

Compare Registry changes made by a program

RegFromApp from Nirsoft is a free portable software available for Windows  x64 as well as x86 machines. Once you have downloaded it, open RegFromApp.

Here, you can find almost all the programs that you have installed on your computer. Select one and hit the OK button.

Following that, whenever that selected program makes any change, it will be stored like this:

RegFromApp has no complicated settings. But, you can change the Display Mode. There are two different display modes, i.e., Show Last Modified Values and Show Original Values.

One thing you should keep in mind is that, if you want to monitor registry changes of a 32-bit program, you will have to download the 32-bit version of RegFromApp. For example, if you are using a 64-bit version of Windows, but you have a 32-bit version of Google Chrome installed. Then you will not be able to use the 64-bit tool to monitor your 32-bit Chrome.
