When you are deleting a program in the registry, you need to be careful as you should only delete the right program, as otherwise you might delete a very important system program, causing the system to crash. It is best to take professional assistance in doing this task so that the editing process happens smoothly.
The system registry controls the system’s core activities. You can edit the system registry in so many different ways. It must be noted that changes made to Windows Registry takes effect immediately and that no backup is done prior to the edit. It is necessary to take a backup of your system disk before performing the task and to also know how to restore the system to normal functioning, in case of an error in the action that you perform.
Let’s take an example of how Registry Editing works. When you uninstall a program, we think it’s been removed from the system, but in reality it is not completely removed. If you want to remove every trace of the program, you need to check the system registry to do this.
The steps involved in editing system registry for removing a program from the system are quite simple. You need to go to the DOS prompt. This can be done by clicking ‘Command Prompt’ from the ‘Start’ menu of the system. Type “regedit.exe” in the Command Prompt and then press enter. The system registry is open and you can check out the program that you wish to uninstall.
Before to begin to use the Registry Editor, you should be aware of how it looks like. The Registry Editor has a tree of folders. This tree looks similar to the file directory in your system. The registry refers to them as ‘keys’ and each key has subkeys, just like the files that can be seen inside a folder.
