Full Specifications. What's new in version 1. Release August 25, Date Added July 5, However, such a previewer can be enabled in previous versions of Windows with the Windows Desktop Update installed through the use of folder customization templates. All Microsoft Office documents since Office 4. File shortcuts can also store comments which are displayed as a tooltip when the mouse hovers over the shortcut.
The shell introduces extensibility support through metadata handlers, icon overlay handlers and column handlers in Explorer Details view. The right pane of Windows Explorer, which usually just lists files and folders, can also be customized.
For example, the contents of the system folders aren't displayed by default, instead showing in the right pane a warning to the user that modifying the contents of the system folders could harm their computer. It's possible to define additional Explorer panes by using DIV elements in folder template files. The Indexing Service has also been integrated into the operating system and the search pane built into Explorer allows searching files indexed by its database.
Microsoft released the version 3. Sparse files allow for the efficient storage of data sets that are very large yet contain many areas that only have zeros. Windows also introduces a Distributed Link Tracking service to ensure file shortcuts remain working even if the target is moved or renamed. The target object's unique identifier is stored in the shortcut file on NTFS 3.
It allows any folder or drive on an NTFS volume to be encrypted transparently by the user. 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 keycipher were used. 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 into 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. 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. Windows included version 7.
Microsoft published quarterly updates to DirectX 9. The majority of games written for versions of DirectX 9. Windows included the same games as Windows NT 4. Windows introduced the Microsoft Management Console MMC , which is used to create, save, and open administrative tools. Each console can contain one or many specific administrative tools, called snap-ins. 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.
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 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 Windows introduced Windows Script Host 2.
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. Instead, an updated version of Windows 98 called Windows 98 Second Edition was released in and Windows Me was released in late While Windows was designed for businesses, Windows Me was designed for home use. Close to the release of Windows Service Pack 1, Microsoft released Windows Datacenter Server, targeted at large-scale computing systems with support for 32 processors, on September 29, Microsoft issued the following statement:.
As such, it is illegal to post it, make it available to others, download it or use it. Despite the warnings, the archive containing the leaked code spread widely on the file-sharing networks. On February 16, , an exploit "allegedly discovered by an individual studying the leaked source code" for certain versions of Microsoft Internet Explorer was reported. The most notable improvement from Windows NT 4. Similar to Windows 9x , Windows supports automatic recognition of installed hardware, hardware resource allocation, loading of appropriate drivers, PnP APIs and device notification events.
The addition of the kernel PnP Manager along with the Power Manager are two significant subsystems added in Windows Windows introduced version 3 print drivers user mode printer drivers. Driver Verifier was introduced to stress test and catch device driver bugs.
Windows introduces layered windows that allow for transparency, translucency and various transition effects like shadows, gradient fills and alpha blended GUI elements to top-level windows. Menus support a new Fade transition effect.
The Start Menu in Windows introduces personalized menus , expandable special folders and the ability to launch multiple programs without closing the menu by holding down the SHIFT key. A Re-sort button forces the entire Start Menu to be sorted by name. The Taskbar introduces support for balloon notifications which can also be used by application developers.
Windows Explorer has been enhanced in several ways in Windows This feature was abused by computer viruses that employed malicious scripts, Java applets, or ActiveX controls in folder template files as their infection vector. Other features new to Explorer include customizable toolbars, auto-complete in address bar and Run box, advanced file type association features and a Places bar in common dialogs.
The "Web-style" folders view, with the left Explorer pane displaying details for the object currently selected, is turned on by default in Windows For certain file types, such as pictures and media files, the preview is also displayed in the left pane. Until the dedicated interactive preview pane appeared in Windows Vista , Windows had been the only Windows release to feature an interactive media player as the previewer for sound and video files, enabled by default.
However, such a previewer can be enabled in previous versions of Windows with the Windows Desktop Update installed through the use of folder customization templates. The default file tooltip displays file title, author, subject and comments; this metadata may be read from a special NTFS stream, if the file is on an NTFS volume, or from an OLE structured storage stream, if the file is a structured storage document.
All Microsoft Office documents since Office 4. File shortcuts can also store comments which are displayed as a tooltip when the mouse hovers over the shortcut. The shell introduces extensibility support through metadata handlers, icon overlay handlers and column handlers in Explorer Details view. The right pane of Windows Explorer, which usually just lists files and folders, can also be customized.
For example, the contents of the system folders aren't displayed by default, instead showing in the right pane a warning to the user that modifying the contents of the system folders could harm their computer. It's possible to define additional Explorer panes by using DIV elements in folder template files. This degree of customizability is new to Windows ; neither Windows 98 nor the Desktop Update could provide it. The Indexing Service has also been integrated into the operating system and the search pane built into Explorer allows searching files indexed by its database.
Windows supports disk quotas , which can be set via the "Quota" tab found in the hard disk properties dialog box. Microsoft released the version 3. 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.
