Sparse files allow for the efficient storage of data sets that are very large yet contain many areas that only have zeros. Reparse points allow the object manager to reset a file namespace lookup and let file system drivers implement changed functionality in a transparent manner.

Volume mount points and directory junctions allow for a file to be transparently referred from one file or directory location to another. It allows any folder or drive on an NTFS volume to be encrypted transparently by the user. To date, its encryption has not been compromised. EFS works by encrypting a file with a bulk symmetric key also known as the File Encryption Key, or FEK , which is used because it takes less time to encrypt and decrypt large amounts of data than if an asymmetric key cipher were used.

The symmetric key used to encrypt the file is then encrypted with a public key associated with the user who encrypted the file, and this encrypted data is stored in the header of the encrypted file.

To decrypt the file, the file system uses the private key of the user to decrypt the symmetric key stored in the file header. It then uses the symmetric key to decrypt the file. Because this is done at the file system level, it is transparent to the user. For a user losing access to their key, support for recovery agents that can decrypt files is built in to EFS.

A Recovery Agent is a user who is authorized by a public key recovery certificate to decrypt files belonging to other users using a special private key. By default, local administrators are recovery agents however they can be customized using Group Policy..

Windows introduced the Logical Disk Manager and the diskpart command line tool for dynamic storage. All versions of Windows support three types of dynamic disk volumes along with basic disks : simple volumes , spanned volumes and striped volumes :. In addition to these disk volumes, Windows Server , Windows Advanced Server , and Windows Datacenter Server support mirrored volumes and striped volumes with parity :. With Windows , Microsoft introduced the Windows 9x accessibility features for people with visual and auditory impairments and other disabilities into the NT-line of operating systems.

It also has support for many different locales. Windows included version 7. Microsoft published quarterly updates to DirectX 9. The majority of games written for versions of DirectX 9. The Windows Computer Management console can perform many system tasks.

It is pictured here starting a disk defragmentation. Windows introduced the Microsoft Management Console MMC , which is used to create, save, and open administrative tools. Each of these is called a console , and most allow an administrator to administer other Windows computers from one centralized computer.

Each console can contain one or many specific administrative tools, called snap-ins. These can be either standalone with one function , or an extension adding functions to an existing snap-in. In order to provide the ability to control what snap-ins can be seen in a console, the MMC allows consoles to be created in author mode or user mode. Author mode allows snap-ins to be added, new windows to be created, all portions of the console tree to be displayed and consoles to be saved.

User mode allows consoles to be distributed with restrictions applied. User mode consoles can grant full access to the user for any change, or they can grant limited access, preventing users from adding snapins to the console though they can view multiple windows in a console.

Alternatively users can be granted limited access, preventing them from adding to the console and stopping them from viewing multiple windows in a single console. The main tools that come with Windows can be found in the Computer Management console in Administrative Tools in the Control Panel.

It contains Disk Management and Removable Storage snap-ins, a disk defragmenter as well as a performance diagnostic console, which displays graphs of system performance and configures data logs and alerts. It also contains a service configuration console, which allows users to view all installed services and to stop and start them, as well as configure what those services should do when the computer starts. REGEDIT has a left-side tree view of the Windows registry , lists all loaded hives and represents the three components of a value its name, type, and data as separate columns of a table.

REGEDT32 has a left-side tree view, but each hive has its own window, so the tree displays only keys and it represents values as a list of strings. It is a command line utility that scans system files and verifies whether they were signed by Microsoft and works in conjunction with the Windows File Protection mechanism.

It can also repopulate and repair all the files in the Dllcache folder. The Recovery Console is run from outside the installed copy of Windows to perform maintenance tasks that can neither be run from within it nor feasibly be run from another computer or copy of Windows It is usually used to recover the system from problems that cause booting to fail, which would render other tools useless, like Safe Mode or Last Known Good Configuration, or chkdsk.

Windows introduced Windows Script Host 2. Screenshot of Windows Server When users try to access a network share off the DFS root, the user is really looking at a DFS link and the DFS server transparently redirects them to the correct file server and share. Domain-based DFS roots exist within Active Directory and can have their information distributed to other domain controllers within the domain — this provides fault tolerance to DFS.

DFS roots that exist on a domain must be hosted on a domain controller or on a domain member server.

A new way of organizing Windows network domains , or groups of resources, called Active Directory, is introduced with Windows to replace Windows NT's earlier domain model. Active Directory's hierarchical nature allowed administrators a built-in way to manage user and computer policies and user accounts, and to automatically deploy programs and updates with a greater degree of scalability and centralization than provided in previous Windows versions.

It is one of the main reasons many corporations migrated to Windows User information stored in Active Directory also provided a convenient phone book-like function to end users. Active Directory domains can vary from small installations with a few hundred objects, to large installations with millions. Active Directory can organise and link groups of domains into a contiguous domain name space to form trees.

Groups of trees outside of the same namespace can be linked together to form forests. Active Directory services could always be installed on a Windows Server , Advanced Server , or Datacenter Server computer, and cannot be installed on a Windows Professional computer.

However, Windows Professional is the first client operating system able to exploit Active Directory's new features. As part of an organization's migration, Windows NT clients continued to function until all clients were upgraded to Windows Professional, at which point the Active Directory domain could be switched to native mode and maximum functionality achieved.

There should be one or more domain controllers to hold the Active Directory database and provide Active Directory directory services. Along with support for simple, spanned and striped volumes, the server family of Windows also supports fault-tolerant volume types. The types supported are mirrored volumes and RAID-5 volumes :.

Windows can be deployed to a site via various methods. It can be installed onto servers via traditional media such as CD or via distribution folders that reside on a shared folder. Installations can be attended or unattended. During a manual installation, the administrator must specify configuration options. Unattended installations are scripted via an answer file , or a predefined script in the form of an INI file that has all the options filled in. An answer file can be created manually or using the graphical Setup manager.

The Winnt. The ability to slipstream a service pack into the original operating system setup files is also introduced in Windows The Sysprep method is started on a standardized reference computer — though the hardware need not be similar — and it copies the required installation files from the reference computer to the target computers. The hard drive does not need to be in the target computer and may be swapped out to it at any time, with the hardware configured later.

Sysprep allows the duplication of a disk image on an existing Windows Server installation to multiple servers. This means that all applications and system configuration settings will be copied across to the new installations, and thus, the reference and target computers must have the same HALs , ACPI support, and mass storage devices — though Windows automatically detects " plug and play " devices.

The primary reason for using Sysprep is to quickly deploy Windows to a site that has multiple computers with standard hardware. Systems Management Server can be used to upgrade multiple computers to Windows It will indicate that your disk drives are Dynamic. Right-click on Disk 0 or Disk 1 and select New Volume…. The New Volume Wizard will appear. Click Next.

A window will appear prompting you to Select the volume you want to create. Select Striped as shown in the screen capture and click Next. Add Disks 0 and Disk 1 to the Selected list. Choose the size of each disk you wish to use for the new striped disk Click Next. Choose the drive letter to assign to the drive and click Next. Click Finish on the next window. You should now see a striped disk in the Computer Management window with the sum capacity of the two areas on the disks that were selected to make the striped array, see the screen capture" There will also remain an area of unallocated space on Disk 1 if the two unused areas did not match in size.

You may format this and use it as additional storage. You must run the operating system from a separate partition. In a two-disk RAID 0 array, the data of the first, third, fifth blocks will be written to the first disk, while the second, fourth, sixth blocks will be written to the second disk. With this data organization, the entire RAID 0 array will fail once one of the disks crashes. All the data on the RAID 1 array will be completely mirrored on each disk. It means that even if one of the disks fails, the data can be restored since it has an exact copy on the second disk.

There is no doubt that RAID 0 provides better storage capacity. Since there is no redundancy, the total storage that you can use for the RAID 0 unit is the sum of all individual disk storage capacities.

However, in a RAID 1 array, the total storage capacity is equal to one hard disk. For instance, you have 2 hard disks with GB. Both of the 2 RAID arrays have their own distinctive features, which decides their different applications.

If the reliability and data security are more important than other aspects, you can choose RAID 1 array. If the good performance is your first consideration, the RAID 0 array is a better choice.

For instance, you can choose RAID 0 array for game playing, HD video capturing, and recording because they require a very fast write speed and a large capacity.
