If Windows or some other program has never assigned a value to a value entry, the value entry contains the null value. This is very different from assigning an empty string to a value entry; an empty string is a string of characters that just happens to be of zero length.

Each subkey represents a mapped drive letter (D, E, F, and so on). Under each drive letter’s subkey, you’ll find a handful of value entries–such as Provider Name, RemotePath, and UserName–that describe the connection. InstallLocationsMRU. This itty-bitty subkey contains the last several paths from which you’ve installed Windows extensions. Windows maintains control sets, each of which determines exactly which device drivers and services Windows loads and how it configures them when Windows starts. For example, a control set provides the various parameters Windows needs when it starts, such as the computer’s name on the network and the current hardware profile.
- Each Key name is unique and has one or more printable characters except Backslash.
- Keys can contain Subkeys, Values and additional Data in each Value.
- Data stored in the Windows Registry is stored in the form of a hierarchy of keys.
- The hierarchy resembles a tree format where each node in the tree is called a Key(Windows Registry Key).
- Applications installed on any Windows OS use the Registry’s Key/Value format through the Registry API to create, delete and change data stored in the database.
Otherwise, select Selected Branch, and REGEDIT automatically fills in the key you selected in step 1. To restart Windows 98 quickly, choose Shut Down from the Start menu. In the Shut Down Windows dialog box, select Restart the Computer and then hold down the Shift key and click OK.
Changes that you make to the Registry might not be reflected immediately in Windows or the programs that are currently running. The only way to make sure is to close REGEDIT and restart Windows or the affected program. Windows 98 stores persistent network connections in HKEY_CURRENT_USER\Network\Persistent.
A control set also controls which device drivers and file systems Windows loads and provides the parameters Windows needs in order to configure each driver. This subkey contains information about the computer’s network security provider, administrative shares (for remote administration), and public shares. Windows 98 keeps track of all the open network connections other users have on your computer in HKEY_LOCAL_MACHINE\Security\Access. An important concept you need to understand is that of an empty value entry.
