Regshot is a small,free and open-source(GPL) registry compare utility that allows you to quickly take a snapshot of your registry and then compare it with a second one - done after doing system changes or installing a new software product. The changes report can be produced in text or HTML format and contains a list of all modifications that have taken place between snapshot1 and snapshot2. In addition, you can also specify folders (with sub filders) to be scanned for changes as well.

Regshot是个简单，实用的注册表比较工具，它通过两次抓取注册表而快速地比较出答案。可以将您的注册表以纯文本方式记录下来，便于浏览；可以监察Win.ini，System.ini中的键值；可以监察您Windows目录和 System 录中文件的变化，为您手工卸载某些软件创造条件。附带源代码。
