How to Open the Registry Key in Windows XP

The windows registry is like the central nervous system for the Windows operating system. It contains the settings for all of the hardware, operating-system files and programs your computer runs. The two main components of the registry are "keys" and "values." Keys are the parameters that control certain functions, and values are the settings for those parameters. Changing these can make the computer run more efficiently, correct problems--or completely crash your system. Because of this, you should only try to edit your registry if you are an expert.

Instructions

1. From the "Start" menu on the taskbar in Windows XP, click "Run..."

2. In the "Open:" dialog box, type "regedit" and click "OK." This will bring up the Windows XP registry editor. Keys will appear as folders in the left portion of the window, and values will appear as files in the right portion.

3. To find a specific key or value, click "Edit" in the menu bar, then click "Find..." Type the name of the key or value you are looking for in the dialog box and click "Find Next." You do not need the full name of the value you are looking for. This function searches for substrings unless the "Match whole string only" check box is activated.

4. To edit a value, right-click the value and select "Modify." This same menu allows you to rename and delete a value as well.

5. Add new keys (and new values to keys) by right-clicking any key. Keys can also be renamed using this same menu.

Tips & Warnings

• There are several good registry cleaners for Windows XP on the market. Before digging into the registry yourself, look into one of these products. They have been tested, and usually have a feature built in that will restore your system if something goes wrong.

• Editing the registry can have dire and irreversible consequences. Do not edit the registry unless you are well-acquainted with its functionality.
