In one of my earlier posts,I had described the way to backup registry through the system state data backup.
Let us take a look on how to go about if we only need to backup registry and nothing else.
1.Open registry editor (Start>Run>regedt32).
2.We will export the current registry settings and save it as a .reg file somewhere.
To do this,click File>Export.
3.Choose a suitable location to store this exported registry file,you may never know when it can come in handy 🙂
4.If possible,store multiple copies of this file in multiple storage devices to improve redundancy.
For Vista,administrator privileges will be needed to open registry editor.The procedure for backup remains the same as in XP.
If more information on what .reg file is and how to use it,check this post on it.
Peace.
