MICROSOFT and WINDOWS


REVERSE HISTORY OF WINDOWS OSs

 

Windows XP (2001)

A client version of Windows 2000 with a redesigned user interface and .NET capability. XP comes in a Home Edition and Professional version, the latter adding more security and administrative capabilities and the capability of being run remotely. XP has improved support for digital photography, gaming, instant messaging and wireless networks. A 64-bit version is also available for Intel's Itanium CPUs.

Windows 2000 (2000)

An updated version of Windows NT 4.0 (originally thought to be named NT 5.0). It added numerous enhancements including Plug and Play and Active Directory. Windows 2000 comes in one workstation version (Windows 2000 Professional) and three server versions, the latter supporting as much as 64GB of memory and as many as 32 CPUs in a single system. See Windows 2000.

Windows NT (1993)

Windows NT 3.5 was introduced two years before Windows 95. It was an entirely different and self-contained operating system and offered separate versions for client and server. Providing greater crash protection than Windows 3.1, its first user interface was the Windows 3.0 Program Manager. In 1996, Version 4.0 was introduced with the Windows 95 interface, but did not include Win 95's Plug and Play capability. Windows NT Server gained significant market share as a server operating system, although the workstation version did not compete very much with other Windows versions.

Windows ME (2000)

An upgrade to Windows 98. ME has a shorter boot time but no longer can be booted into DOS only (DOS sessions can still be run in a Windows window).

98 (1998) & Second Edition

An upgrade to Windows 95 that tightly integrated the Internet Explorer Web browser with the OS. It added support for the Universal Serial Bus (USB) and dual monitors. In 1999, Windows 98 Second Edition fixed numerous bugs by incorporating Service Pack 1 with upgraded applications including Internet Explorer 5 and Outlook Express 5.

Windows 95 (1995) and OSR2

Windows 95 introduced a new user interface that added more Macintosh features. It included preemptive multitasking, which allows programs to be timeshared together more effectively than in Windows 3.1, and Plug and Play, which makes adding new peripherals much easier than Windows 3.1. Unlike Windows 3.1, which was loaded after booting up with DOS, Windows 95 was a self-contained 32-bit operating system that boots with its own version of DOS. Windows 95 ran most Windows 3.x and DOS applications, and within a couple of years, support for earlier 16-bit Windows applications was dropped by most vendors. In 1996, an upgrade known as Win95B or OS Release 2 (OSR2) added support for FAT32 files and 32-bit CardBus PC cards.

Windows 3.1 (1992)

An upgrade to Windows 3.0 that provided a more stable and faster environment. It added multimedia support, TrueType fonts, drag & drop commands and OLE compound documents. Windows for Workgroups was later introduced with built-in networking, allowing PCs to share data and programs when fitted with network adapters. Windows for Workgroups 3.11 was the last 3.x version. Windows 3.1 is rarely used anymore.

Windows 3.0 (1990)

"First Real Windows"

Windows 3.0 put Windows on the map. Its ability to manage more than one megabyte of memory, which was a serious limitation in DOS. Its built-in DOS extender could manage 16MB of RAM, a huge amount for that time, and its Program Manager user interface was widely accepted. It still required DOS to be booted first, but Windows added multitasking, cut and paste capability between applications and centralized printer and font management, all of which were sorely lacking in DOS. Within a couple of years, Windows would become the major desktop operating system worldwide.

Windows 1.0 (1985)

Version 1.0 of Windows was introduced in 1985, but barely made a dent in the market. Subsequent versions (Windows 2.0, Windows/386) began to make some inroads, and a handful of companies adopted Windows as their operating environment. However, it wasn't until Version 3.0 that Windows had any impact. The PCs of the time were also terribly underpowered for a graphics-based interface.


ADD/REMOVE PROGRAMS COMPLETELY

 

It's typically good practice to use the Add/Remove Programs applet in Control Panel to remove software from Windows 98, unless the programs provide an Uninstall utility that's clearly marked in the Start menu. Sometimes, however, Windows 98 just doesn't seem to want to let go of third-party applications and finds some reason why it cannot uninstall them cleanly. Usually when this happens, the title remains on the Add/Remove Programs list, and reselecting the title for removal simply displays an error, leaving the title where it is.

You can resolve this issue with a quick registry edit. Using the Registry Editor, you can remove these entries from the list manually. After opening the Registry Editor (Regedit.exe), navigate to the following key:

HKEY_LOCAL_MACHINE\Software \Microsoft \Windows\CurrentVersion \Uninstall.

Remove the key below this level that corresponds to the application you want to delete. For example, with the key above, you would remove the following:

HKEY_LOCAL_MACHINE\Software \Microsoft \Windows\CurrentVersion \Uninstall\iShare

When you open the Add/Remove Programs applet in Control Panel, the application should no longer be present.

NOTE: Editing the registry is risky, so be sure you have a verified backup before making any changes.

MS WINDOWS XP MEDIA CENTER

 

With the next generation of Media Centre PCs, you'll be able to have your TV and record it too. [Picture shows Remote Control and Portable Media Center].

For the first time, Microsoft's Windows XP Media Centre Edition is supporting multiple tuners, meaning that consumers will be able to watch one channel while recording another or record two stations at once, CNET News.com has learned. The feature is one of several improvements Microsoft has made with Windows XP Media Centre Edition 2005, an update that the company plans to announce next week.

At the same time, Microsoft is also allowing computer makers to create Media Centre PCs that lack the TV recording feature altogether, a move that will allow computer makers to offer PCs with the operating system for less than $US 800. It's all part of an effort by Microsoft to position Media Centre as a more mainstream consumer OS.

Without an all-new version of Windows until Longhorn in 2006, Microsoft is hoping that an improved Media Centre OS can help reignite interest in the 3-year-old Windows XP operating system. The launch of the updated Media Centre, along with several new companion products, will form a key part of Microsoft's fall marketing blitz designed to sell consumers on the benefits of XP.

The entertainment-oriented Media Centre OS is similar to other flavours of Microsoft's flagship Windows XP, but adds a second interface that can play movies, music, digital pictures or television and be controlled via remote control. In its first two incarnations, Media Centre has attracted only a niche of the PC market, largely those interested in recording TV shows onto their hard drives.

Microsoft has thus far been largely mum about the new version of Media Centre OS, though details have begun to trickle out. As previously reported, the new version has several new features designed to address current shortcomings, such as the ability to burn CDs and DVDs from within the remote-controlled interface.

Sources tell CNET News.com that the product will also include the ability to exchange MSN-compatible instant messages while doing other things, such as watching television or viewing a photo slideshow. The instant messages appear as an overlay to the TV or other main image.

Media Centre Edition 2005 will offer limited support for high-definition television, but only the type of high-definition signal received through an antenna--not high-definition satellite or cable. Microsoft declined to comment on the new version of Media Centre or its features.

Much of the focus with the new version, which is code-named Symphony, has been on improving the audio and video quality, with the goal being to rival consumer electronics devices such as DVD players and digital video recorders that cost far less and have outshined the Media Centre in quality. With this version, sources say, they believe Microsoft has at least caught up to TiVo. The program guide has also been improved, including the ability to browse upcoming movies using "cover art" images.

Microsoft has also announced plans for two products that will complement the new OS. One is a handheld device known as a Portable Media Center that will allow content from a Media Center PC to be taken on the go. The other is a type of set-top box known as a Media Center Extender, which allows consumers to view content in one room that is stored on a Media Center PC in another room.

The company is expected to use next week's "Experience More" event in Los Angeles to tout other digital home efforts, including several moves designed to make it easier to move content around the home while still offering digital rights management. For example, Microsoft has been developing technology, code-named Janus, that paves the way for a new class of portable music devices capable of playing music that is rented on a subscription basis rather than purchased. And, in addition to Media Center extenders, which work only with Media Center PCs, Microsoft has a broader Windows Media Connect effort designed to let many different living-room products grab video, music and photos that are stored on a Windows XP computer.

Some details have come from the companies making Media Center products. Two tuner manufacturers, Hauppauge and Vixs have announced dual-tuner products that are designed specifically to work with Media Center 2005. Computer makers are also starting to tip their hand. Sony, for example, posted several new models to its SonyStyle Web site. Best Buy has also started listing at least one of the new Sony models.

The machines are part of Sony's existing "R" series of Vaio Desktops. In addition to sporting the new OS, the machines add faster processors and larger hard drives as well as the option to automatically create a backup of data using RAID. For now, Sony's machines stick to offering a single TV tuner.

Hewlett-Packard has announced its Digital Entertainment Center, a Media Center device that is designed to look more like a consumer electronics device than a PC and is also expected to offer dual tuners, among other features. HP has yet to announce pricing or when the device will be available, though. The company is also expected to have more traditional Media Center PCs and is expected to offer an upgrade program for existing Media Center PCs, but details are not yet available.

Dell, Gateway and Toshiba are among the other big-name computer makers expected to offer machines with the new operating system, sources said.

As for the Media Center extenders, HP has announced plans to offer such a device and online retailer Buy.com has started taking orders for a similar product from Linksys. Creative and Samsung recently started selling the first Portable Media Centers.

All of the Microsoft devices find themselves competing, at least to some degree, with non-Microsoft alternatives. In the portable category, RCA and Archos offer competing portable video players that do not interface directly with Media Center. There are also other companies that offer features similar to Media Center both for Linux and Windows-based machines.

Intel showed off many such designs at its recent developer forum, though it is unclear how many big-name PC makers will choose to offer entertainment-oriented PCs that are not Microsoft-based. Instead, the challenge may come more from consumer electronics makers.

Devices that could both burn DVDs and record TV shows were once rare but are increasingly more common. Cable and satellite operators are also starting to ship digital video recorders in larger numbers, again potentially challenging Microsoft's Media Center ambitions.
