I have uninstalled a program that I do not want to have uninstall.
I have shadow copies of the entire disk so the files are there. How can I revert the entire system to a shadow copy?
I'm using Vista
You need to use System Restore, assuming it created a checkpoint before you uninstalled the program.
If you goto the folder where the program was installed and right click on the folder you will see previous versions. From within there you can restore a particular state.
This may not make your program work as it is likely the installer installed items other than just files such as registry settings.
