introduction: registry editor is an advanced tool for viewing and changing settings in your system registry, which contains information about how your computer runs. almost the entire settings are stored in the registry. for example, when you resize an application window, the window position (x,y points) is stored in the registry so that the settings are retained permanently. this is just an example, there are much more data stored in the registry, right from your user account names and passwords (if configured to store in the registry). although registry editor enables you to inspect and modify the registry, it's advisable to use registry editor only if the gui does not provide the option you're looking for. making incorrect changes in the registry can break your system. it's highly advisable to backup the registry before editing any portion of it. backing up the xp registry - three methods method 1: using system restore one way to backup the registry is to create a system restore snapshot. system restore returns your computer to a previous snapshot without losing recent personal information, such as documents, history lists, favorites, or e-mail. it monitors the computer and many applications for changes and creates restore points. you restore these snapshots when your configuration isn't working. this method is unreliable in case you want to rollback the registry changes made a longtime ago, in which case the system restore might have purged that particular restore point - due to space constraints or due to a recent system restore point or even a restore point corruption. please remember, system restore points get deleted for many reasons, making it unreliable, especially in the long run. for more help, see : creating a system restore point and using system restore to undo changes if problems occur
