Actually there are several methods to backup Windows registry. Some of them, I’m discussing in this article.

Method 1: Using System Restore

When we create a system restore point in Windows XP, it backs up the following items:

• Registry
• DllCache
• Local User Profile
• COM+ and WMI databases
• IIS Metabase

So if you want to backup the registry, creating a restore point is the safest way to do so. To create a restore point go to Start –> All Programs –> Accessories –> System Tools –> System Restore. Create a system restore point from there.

Medhod 2: Backing up Individual registry keys

If you want to backup individual registry keys, go to Start –> Run –> regedit
This will open the registry editor. Go to the registry you want to backup, right click it and select Export.

Method 3: Backing up the whole registry

To backup the whole registry, go to Start –> Run –> regedit
This will open the registry editor. Go to File –> Export. This will open the save registry dialog. After the name, select “All” from Export Range and save the registry.

Method 4:

This method is very old but still usable for dial-up internet users.

Use the below method to resume internet connection while LogOff / Fast User Switching,

Start -> Run then type regedit and press enter

Locate the following entry,

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Right-click within the right pane, select New and then select String Value, and give name as

KeepRasConnections

and press enter, then double click on KeepRasConnections and set the value to 1. Close the Registry Editer and restart your PC. Now, your dial-up internet connection will resume after LogOff / Fast User Switching.
