Since Windows 95 and NT4, Microsoft has grouped all of the necessary information for the computer to function into two files (user.dat and system.dat), viewable and editable from the Regiedt program. The group of the programs is what makes up the “Windows Registry”.
You should be careful as this database is the heart of Windows and should only be modified with care, with problems quickly appearing due to a change gone worng.
It is for this reason that all changes that are made on the Windows registry should only be done after backing it up. This is strongly recommended so that if there is a problem you can restore the previous, functional version.
This tip will look at:
Backing up the Windows registry
Restoring the Windows registry from a backup.
The change is very simple and will only take a few seconds. To know more, follow the guide:
Click “Start”, “Run” and type “regedit”. Click “OK” and you will have the Windows Registry open in front of you.
Once the editor is open, go to the “File” lenu and click on “Export”.
Now windows explorer (by default the “My Documents”) will be diaplyed displayed. So that you know where your files are, create a new folder and call this “Registry Backup” so that we can put all of the saved files in here. Once this has been created, or you have chosen your desired location, you will need to give your backup a name. In our test we will name this “Savetest”, press enter or click on the “Save” button so that the backup can be completed.
Note: It is wise to go to the folder where the backup was saved to verify that the backup has been correctly saved.
