Top Articles. We look at the history of Windows Read more. 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.
