The Windows Registry is the centralized configuration database for Windows NT and Windows 2000, as well as for applications. The Registry in Windows 10/8/7 stores information about tuning parameters, device configuration, and user preferences.
On disk, the Windows Registry isn’t simply one large file, but a set of discrete files called hives. Each hive contains a Registry tree, which has a key that serves as the root (i.e., starting point) of the tree. Subkeys and their values reside beneath the root.
Location of Windows Registry files
The location of these registry hives are as follows:
HKEY_LOCAL_MACHINE SYSTEM : system32configsystem
HKEY_LOCAL_MACHINE SAM : system32configsam HKEY_LOCAL_MACHINE SECURITY : system32configsecurity HKEY_LOCAL_MACHINE SOFTWARE : system32configsoftware HKEY_USERS UserProfile : winntprofilesusername HKEY_USERS.DEFAULT : system32configdefault
The supporting files are as follows:
Acer support drivers. Some hives are volatile and don’t have associated files. The system creates and manages these hives entirely in memory; the hives are therefore temporary. The system creates volatile hives every time the system boots. Examples are: Recover files from lost partition free.
HKEY_LOCAL_MACHINE HARDWARE : Volatile hive
HKEY_LOCAL_MACHINE SYSTEM Clone : Volatile hive
These files are database files, and only RegEdit, Regedit32 and the Kernel32 can read them. The primary tool in Windows 10/8/7 for working directly with the registry is Registry Editor. To access it, simply type Regedit in Start Menu Search Bar and hit Enter.

UPDATE: AccidentalADMIN has made a useful comment. He says:
Every Windows got a registry Key which lists every hive in the system. Run regedit to open the Registry Editor and navigate to the following key to get a complete list:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlhivelist

Because registry entries are properties of keys and, as such, cannot be directly browsed, we needto take a slightly different approach when working with them.
Listing Registry Entries
There are many different ways to examine registry entries. The simplest way is to get the propertynames associated with a key. For example, to see the names of the entries in the registry key
HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersion , use Get-Item . Registry keyshave a property with the generic name of 'Property' that is a list of registry entries in the key.The following command selects the Property property and expands the items so that they aredisplayed in a list:
To view the registry entries in a more readable form, use
Get-ItemProperty :
The Windows PowerShell-related properties for the key are all prefixed with 'PS', such asPSPath, PSParentPath, PSChildName, and PSProvider.
You can use the
*.* notation for referring to the current location. You can use Set-Location to change to the CurrentVersion registry container first:
Alternatively, you can use the built-in HKLM PSDrive with
Set-Location :
You can then use the
*.* notation for the current location to list the properties withoutspecifying a full path:
Path expansion works the same as it does within the file system, so from this location you can getthe ItemProperty listing for
HKLM:SOFTWAREMicrosoftWindowsHelp by usingGet-ItemProperty -Path .Help .
Getting a Single Registry EntryHow To Access To Hkey_local_machine
If you want to retrieve a specific entry in a registry key, you can use one of several possibleapproaches. This example finds the value of DevicePath in
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersion .
Using
Get-ItemProperty , use the Path parameter to specify the name of the key, and theName parameter to specify the name of the DevicePath entry.
This command returns the standard Windows PowerShell properties as well as the DevicePathproperty.
Note
Although
Get-ItemProperty has Filter, Include, and Exclude parameters, they cannotbe used to filter by property name. These parameters refer to registry keys, which are itempaths and not registry entries. Registry entries which are item properties.
Another option is to use the Reg.exe command line tool. For help with reg.exe, type
reg.exe /? at a command prompt. To find the DevicePath entry, use reg.exe as shown in the following command:
You can also use the WshShell COM object as well to find some registry entries, although thismethod does not work with large binary data or with registry entry names that include characterssuch as '). Append the property name to the item path with a separator:
Setting a Single Registry Entry
If you want to change a specific entry in a registry key, you can use one of several possibleapproaches. This example modifies the Path entry under
HKEY_CURRENT_USEREnvironment . ThePath entry specifies where to find executable files.
Note
Although
Set-ItemProperty has Filter, Include, and Exclude parameters, theycannot be used to filter by property name. These parameters refer to registry keys—which are itempaths—and not registry entries—which are item properties.
Another option is to use the Reg.exe command line tool. For help with reg.exe, type reg.exe /?at a command prompt.
The following example changes the Path entry by removing the path added in the example above.
Get-ItemProperty is still used to retrieve the current value to avoid having to parse the stringreturned from reg query . The SubString and LastIndexOf methods are used to retrieve thelast path added to the Path entry.
Creating New Registry Entries
To add a new entry named 'PowerShellPath' to the CurrentVersion key, use
New-ItemProperty with the path to the key, the entry name, and the value of the entry. For this example, we willtake the value of the Windows PowerShell variable $PSHome , which stores the path to theinstallation directory for Windows PowerShell.
You can add the new entry to the key by using the following command, and the command also returnsinformation about the new entry:
The PropertyType must be the name of a Microsoft.Win32.RegistryValueKind enumeration memberfrom the following table:
Note
You can add a registry entry to multiple locations by specifying an array of values for thePath parameter:
You can also overwrite a pre-existing registry entry value by adding the Force parameter to any
New-ItemProperty command.
Renaming Registry Entries
To rename the PowerShellPath entry to 'PSHome,' use
Rename-ItemProperty :
To display the renamed value, add the PassThru parameter to the command.
Deleting Registry EntriesHow To Get To Hkey_local_machine System Currentcontrolset Services
To delete both the PSHome and PowerShellPath registry entries, use
Remove-ItemProperty :
