You will be able to perform the following operations:
á1. Registry snapshot for a specific date
á2. Compare registry data with a previous snapshot
á3. Follow the changes, which software makes in the registry during installation/un-installation
á4. Apply undo in the registry towards a status before software installation.

áHint1. To use the whole of software features, install application via Clean My Registry!

Hint2. After un-installation some applications leave some keys in the Windows registry (installation date, registration data, etc.). To track them down, first, you need to install an application via Clean My Registry, which will take a snapshot of your pre-installation Windows registry, and then, when you decide to un-install the application, you can use item 4 in the "Advanced" feature window to track software traces in the registry and completely un-install (optional) the application if necessary.
