SuperFetch is a performance enhancement introduced in [[Microsoft]] [[Windows|Windows Vista]] to reduce the time necessary to launch applications. SuperFetch works with the memory manager service in Windows to analyze memory usage patterns over time to determine the optimal memory content for a given user for a date or time of day. This differs from the [[Prefetch]] technique used in Microsoft Windows XP, which preloads data into memory without analyzing usage patterns.
+
'''Windows''' is a widely-spread [[operating system]] from [[Microsoft]].
  
From [http://msdn.microsoft.com/en-us/library/windows/hardware/dn653317(v=vs.85).aspx]: SuperFetch prioritizes the following kinds of pages to remain in memory:
+
There are 2 main branches of Windows:
* Pages of applications that are used most frequently overall.  
+
* the DOS-branch: i.e. Windows 95, 98, ME
* Pages of applications that are commonly used when resuming:  
+
* the NT-branch: i.e. Windows NT 4, XP, Vista
** After extensive hibernation (for example, first thing in the morning).
+
** After shorter periods of sleep or hibernation (for example, after lunch).
+

== Features ==
 +
* Basic and Dynamic Disks, see: [http://msdn.microsoft.com/en-us/library/windows/desktop/aa363785(v=vs.85).aspx]
  
== Configuration ==
+
=== Introduced in Windows NT ===
 +
* [[NTFS]]
  
Because SuperFetch appears to leave a system with no available memory, some users turn it off to create the appearance of having more free memory. The feature can be configured by changing the <tt>HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters\EnableSuperfetch</tt> [[Registry]] key [http://www.codinghorror.com/blog/archives/000688.html]. A value of zero disables SuperFetch, one enables it for booting only, two for applications, and three for both applications and boot. This setting can also be changed using the Services console, <tt>services.msc</tt> [http://tiredblogger.wordpress.com/2007/03/27/superfetch-not-so-super-for-gaming/].
+
=== Introduced in Windows 2000 ===
  
== File Formats ==
+
=== Introduced in Windows XP ===
 +
* [[Prefetch]]
 +
* System Restore (Restore Points); also present in Windows ME
  
Data for SuperFetch is gathered by the <tt>%SystemRoot%\System32\Sysmain.dll</tt>, part of the Service Host process, <tt>%SystemRoot%\System32\Svchost.exe</tt>, and stored in a series of files in the <tt>%SystemRoot%\Prefetch</tt> directory [http://www.microsoft.com/technet/technetmag/issues/2007/03/VistaKernel/]. These files appear to start with the prefix <tt>Ag</tt> and have a <tt>.db</tt> extension. The format of these files is not fully known, there is available unofficial partial specification [http://blog.rewolf.pl/blog/?p=214] and open source (GPL) dumper for .db files [http://code.google.com/p/rewolf-superfetch-dumper/]. Some information can be gleaned from these files by searching for [[Unicode]] [[strings]] in them.

Windows is a widely-spread operating system from Microsoft.

There are 2 main branches of Windows:

  • the DOS-branch: i.e. Windows 95, 98, ME
  • the NT-branch: i.e. Windows NT 4, XP, Vista

Features

  • Basic and Dynamic Disks, see: [1]

Introduced in Windows NT

Introduced in Windows 2000

Introduced in Windows XP

  • Prefetch
  • System Restore (Restore Points); also present in Windows ME

SP2

  • Windows Firewall

Introduced in Windows Server 2003

  • Volume Shadow Copies

Introduced in Windows Vista

Introduced in Windows Server 2008

Forensics

Partition layout

Default partition layout, first partition starts:

  • at sector 63 in Windows 2000, XP, 2003
  • at sector 2048 in Windows Vista, 2008, 7

Filesystems

Recycle Bin

The Recycle Bin contains "Recycled" files. Moving files and directories to the Recycle Bin is also referred to as soft deletion, since the files are not removed from the file system.

RECYCLER

The Recycler format is used by Windows 2000, XP.

Per user Recycle Bin folder in the form:

C:\Recycler\%SID%\

Which contains:

  • INFO2 file; "Recycled" files metadata

$RECYCLE.BIN

The $Recycle.Bin is used as of Windows Vista.

Per user Recycle Bin folder in the form:

C:\$Recycle.Bin\%SID%\

Which contains:

  • $I files; "Recycled" file metadata
  • $R files; the original data

Registry

The Windows Registry is a database of keys and values that provides a wealth of information to forensic investigators.

Thumbs.db Files

Thumbs.db files can be found on many Windows systems. They contain thumbnails of images or documents and can be of great value for the investigator.

See also: Vista thumbcache.

Browser Cache

Browser History

The Web Browser History files can contain significant information. The default web browser that comes with Windows is Microsoft Internet Explorer but other common browsers on Windows are Apple Safari, Google Chrome, Mozilla Firefox and Opera.

Search

See Windows Desktop Search

Setup API Logs

Windows Vista introduced several new Setup API Log files.

Also see [2].

Sleep/Hibernation

After (at least) Windows 7 recovers from sleep/hibernation there often is a system time change event (event id 1) in the event logs.

Users

Windows stores a users Security identifiers (SIDs) under the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

The %SID%\ProfileImagePath value should also contain the username.

Windows Error Reporting (WER)

As of Vista, for User Access Control (UAC) elevated applications WER reports can be found in:

C:\ProgramData\Microsoft\Windows\WER\

As of Vista, for non-UAC elevated applications (LUA) WER reports can be found in:

C:\Users\%UserName%\AppData\Local\Microsoft\Windows\WER\

Corresponding registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting

Advanced Format (4KB Sector) Hard Drives

Windows XP does not natively handle drives that use the new standard of 4KB sectors. For information on this, see Advanced Format.

%SystemRoot%

The actual value of %SystemRoot% is store in the following registry value:

Key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\
Value: SystemRoot
