== New Features ==

==File Locations==
The following new features were introduced in Windows 8:
+
The Windows Registry is stored in multiple files.
* [[Windows Shadow Volumes | File History]]
+
* [[Windows Storage Spaces | Storage Spaces]]
+
* [[Resilient File System (ReFS)]]; server edition will likely be available in Windows Server 2012
+
  
=== Windows 8.1 ===
+
===Windows NT 4 ===
 +
In Windows NT 4 (and later) the Registry is stored in the [[Windows NT Registry File (REGF)]] format.
  
== Jump Lists ==
+
Basically the following Registry hives are stored in the corresponding files:
[[Jump Lists]] are Task Bar artifacts that were first introduced on Windows 7 and are also available on Windows 8.
+
* HKEY_USERS: \Documents and Setting\User Profile\NTUSER.DAT
 +
* HKEY_USERS\DEFAULT: C:\Windows\system32\config\default
 +
* HKEY_LOCAL_MACHINE\SAM: C:\Windows\system32\config\SAM
 +
* HKEY_LOCAL_MACHINE\SECURITY: C:\Windows\system32\config\SECURITY
 +
* HKEY_LOCAL_MACHINE\SOFTWARE: C:\Windows\system32\config\software
 +
* HKEY_LOCAL_MACHINE\SYSTEM: C:\Windows\system32\config\system
  
== Registry ==
+
===Windows 9x/ME===
The [[Windows_Registry|Windows Registry]] remains a core component of the Windows operating system.
+
In Windows 95, 98, Me the Registry is stored in the [[Windows 9x Registry File (CREG)]] format.

 +
 
 +
== Special cases ==
 +
The Windows Registry has several special case scenarios, mainly concerning key and value name, that are easy to fail to account for:
 +
* special characters key and value names
 +
* duplicate key and value names
 +
* the names when stored in extended ASCII (ANSI string) use a codepage that is dependent on the system settings
 +
 
 +
=== special characters key and value names ===
 +
Both key and values names are case insensitive. The \ character is used as the key separator. Note
 +
that the \ character can be used in value names. The / character is used in both key and value names.
 +
Some examples of which are:
 +
<pre>
 +

File Locations

The Windows Registry is stored in multiple files.

Windows NT 4

In Windows NT 4 (and later) the Registry is stored in the Windows NT Registry File (REGF) format.

Basically the following Registry hives are stored in the corresponding files:

  • HKEY_USERS: \Documents and Setting\User Profile\NTUSER.DAT
  • HKEY_USERS\DEFAULT: C:\Windows\system32\config\default
  • HKEY_LOCAL_MACHINE\SAM: C:\Windows\system32\config\SAM
  • HKEY_LOCAL_MACHINE\SECURITY: C:\Windows\system32\config\SECURITY
  • HKEY_LOCAL_MACHINE\SOFTWARE: C:\Windows\system32\config\software
  • HKEY_LOCAL_MACHINE\SYSTEM: C:\Windows\system32\config\system

Windows 9x/ME

In Windows 95, 98, Me the Registry is stored in the Windows 9x Registry File (CREG) format.

  • \Windows\user.dat
  • \Windows\system.dat
  • \Windows\profiles\user profile\user.dat

Keys

Run/RunOnce

System-wide:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce

Per user:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce

Special cases

The Windows Registry has several special case scenarios, mainly concerning key and value name, that are easy to fail to account for:

  • special characters key and value names
  • duplicate key and value names
  • the names when stored in extended ASCII (ANSI string) use a codepage that is dependent on the system settings

special characters key and value names

Both key and values names are case insensitive. The \ character is used as the key separator. Note that the \ character can be used in value names. The / character is used in both key and value names. Some examples of which are:

Key: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\NetBT\Parameters\
Value: Size/Small/Medium/Large
Key: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Terminal Server\VIDEO\disc\
Value: \Device\Video0
Key:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\services\xmlprov\Parameters\SchemaGroups\User\http://www.microsoft.com/provisioning/eaptlsuserpropertiesv1\
Value: SchemaFile

codepaged ASCII strings

Value with name "ëigenaardig" created on Windows XP codepage 1252.

value key data:
00000000: 76 6b 0b 00 46 00 00 00  20 98 1a 00 01 00 00 00   vk..F...  .......

00000020: 55 4e 49 43                                        UNIC

value key signature                     : vk
value key value name size               : 11
value key data size                     : 0x00000046 (70)
value key data offset                   : 0x001a9820
value key data type                     : 1 (REG_SZ) String
value key flags                         : 0x0001
        Value name is an ASCII string

value key unknown1                      : 0x6e69 (28265)
value key value name                    : ëigenaardig
value key value name hash               : 0xb78835ee
value key padding:
00000000: 00 55 4e 49 43                                     .UNIC

As you can see the name is stored in extended ASCII (ANSI) using codepage 1252.
