==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 98/ME===
 
* \Windows\user.dat
 
* \Windows\system.dat
 
* \Windows\profiles\user profile\user.dat
 
 
== Keys ==
 
 
=== Run/RunOnce ===
 
System-wide:
 
<pre>
 
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
 
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
 
</pre>
 
 
Per user:
 
<pre>
 
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
 
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
 
</pre>
 
 
== 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>
 
Key: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\NetBT\Parameters\
 
Value: Size/Small/Medium/Large
 
</pre>
 
 
<pre>
 
Key: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Terminal Server\VIDEO\disc\
 
Value: \Device\Video0
 
</pre>
 
 
<pre>
 
Key:
 
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\services\xmlprov\Parameters\SchemaGroups\User\http://www.microsoft.com/provisioning/eaptlsuserpropertiesv1\
 
Value: SchemaFile
 
</pre>
 
 
=== codepaged ASCII strings ===
 
 
Value with name "ëigenaardig" created on Windows XP codepage 1252.
 
 
<pre>
 
value key data:
 
00000000: 76 6b 0b 00 46 00 00 00  20 98 1a 00 01 00 00 00  vk..F...  .......
 
00000010: 01 00 69 6e eb 69 67 65  6e 61 61 72 64 69 67 00  ..in.ige naardig.
 
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
 
</pre>
 
 
As you can see the name is stored in extended ASCII (ANSI) using codepage 1252.
