How To Backup Registry Files

Windows configuration information is in the registry. Here's a look at what's stored in the registry:

-Windows system configuration
-Hardware configuration
-Installed programs
-Types of documents each program can create
-User preferences

Registry files contain data in keys, subkeys, and named values. If the registry is not edited correctly, your system could sustain severe damage. Microsoft says you should backup registry files before editing the registry.

Registry files can be found in the following places:

Windows 2000, XP, Vista- C:\Documents and Settings\User Name\

Windows 2000, XP, Vista- C:\Windows\System32\Config\

Windows 95, 98, ME- C:\Windows\

Windows 95, 98, ME- C:\Windows\Profiles\

You can find registry files here:

Windows 95, 98 and ME- System.dat, User.dat, and Policy.pol

Windows NT, 2000, XP, Vista- Security, System.alt, Default, Sam, Software, System, Ntuser.dat

How to back up Windows registry files?

You are not allowed to back up registry files under Windows NT, 2000, XP, and Vista, while the system is running. Registry files are locked, so there is no way to reach these registry files. But, you can use an integrated Windows XP's System Restore option to backup your registry files.

1. Go to Start, and then go to Run.

2. In Open, type regedit, and then hit OK.

3. Locate and then hit the root subkey that contains all the child subkeys and values that will be backed up

4. On the File menu, hit Export.

5. In Save, select a location where you want to save the Registration Entries (.reg) file, type a file name in the File name box, and then hit Save.

Backing up registry files in Windows 95, 98, and ME is pretty easy. For Windows NT, 2000, XP, and Vista, it's much more difficult. A registry repair program will find the correct locations and back up all of your registry data in an automatic, quick and safe manner
