How do you open registry editor?

The Windows registry is a central database of information needed to configure your computer system for general settings and preferences, software applications, and hardware drivers and devices. Keeping your registry in a good state of repair and conducting regular maintenance is imperative because the registry contains important data that is used all the time during system operation.

1. Click Start

2. Click Run

3. Type REGEDIT


4. Click OK

5. The Registry Editor will now open

Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer. Whenever possible, use tools and programs other than Registry Editor to edit the registry.

Some previous versions of Windows had two versions of Registry Editor: regedit.exe and regedt32.exe. The version of Registry Editor that ships with the Windows Server 2003 family replaces both versions from previous operating systems.

Do not run Registry Editor as Administrator, except when necessary.
A malicious user who has access to Registry Editor running as Administrator can cause severe damage to the operating system and software. Only run Registry Editor as Administrator if you need to see or change keys that you cannot otherwise access.

Use Run as to run Registry Editor as Administrator or a different user.
To maintain registry security when making changes to a key that requires administrative credentials, log in as a member of the Users group and run Regedit as an administrator by right-clicking the Regedit icon, clicking Run as, and choosing an account in the local Administrators group. The Regedit icon does not appear by default from the Start menu. To access the icon, open the Windows or WINNT folder on your computer.

Do not access HKEY_CURRENT_USER or HKEY_CLASSES_ROOT using services that impersonate more than one user.
HKEY_CURRENT_USER and HKEY_CLASSES_ROOT are aliases for other keys in the registry. For example, HKEY_CURRENT_USER is an alias for the key in HKEY_USERS for the user who is currently logged in. If a service accesses one of these keys while running as one user, and again while running as another user, the operating system might still have the alias data cached from the first user. If this happens, an error will result because the second user will not have access rights for keys belonging to the first user.

Changes are not necessary when you have a new system even though within a very short period, your registry will quickly grow as you install and remove software and hardware. Usually, within six months, your Windows Registry will become highly fragmented with regular use; and, if you add and remove software and hardware frequently or often effect changes within your system, your registry may corrupt and be full of errors.

Statistics show that about 94% of computers have corrupt and possibly harmful files. On average, almost each PC will have about 150+ errors on them due to corrupt or missing registry entries.

If you are experiencing system crashes or if some of your installed applications are freezing or seizing for no obvious reason, your best bet is to defragment, clean and repair your Registry.

Keeping your system free of registry problems and fragmented entries is difficult even for the most experienced of users. The task is daunting and rather confusing simply because there are so many registry entries and detailed knowledge is required to effect any changes and not cause damage.
