Certain troubleshooting techniques require editing the Windows registry. However, it is always a good precaution to save a backup of the registry before doing any edits in case something goes wrong. This will allow you to recover your Windows installation.
There are several methods or tools available to backup the Windows Registry. A common method is described here. For other methods, see Windows On-Line Help. For Windows XP and Windows ME, see also Article 670: How to Create a Windows XP or ME Restore Point Windows Registry Editor program (REGEDIT)
- From the Windows Start menu, click Run
- In the Open field, type Regedit and click OK.
- From the Registry menu and click Export Registry File.

- Click Save. A copy of your computer's Registry is now backed-up.
- If possible, boot the computer to the Windows desktop, or boot the computer to Safe Mode
- Note:If you have problems booting to Safe Mode, see Technical Document 102: How Do I Boot into Safe Mode? for additional instructions.
- Using Windows Explorer, navigate to the folder where you saved your backup registry file. Double-click the file.
- or If you saved the file in your Desktop folder, double-click the Registry icon on your desktop. The backup is automatically merged into the registry and restores the previous values.
- If you've booted to Safe Mode, restart your computer and return to your normal mode.
