Windows ME

**Windows Millennium Edition**, or Windows ME (marketed with the pronunciation of the pronoun "me" and codenamed **Millennium**), is a graphical operating system developed by Microsoft as part of its Windows 9x family of operating systems. It is the successor to Windows 98 Second Edition (SE), and was released to manufacturing on June 19, 2000, with general availability on September 14, 2000.

Windows ME was the last operating system released in the Windows 9x series which was targeted specifically at home PC users, and included Internet Explorer 5.5, Windows Media Player 7, and the then-new Windows Movie Maker software, which provided basic video editing and was designed to be easy to use for home users. Microsoft also incorporated features first introduced in Windows 2000, which had been released as a business-oriented operating system seven months earlier, into the graphical user interface, shell, and Windows Explorer.

Windows ME was a continuation of the Windows 9x model and still DOS-based like its predecessors, albeit with restricted access to real mode MS-DOS in order to decrease system boot time. In October 2001, Windows XP was released to the public, and became the successor of Windows ME, popularizing most of its features and introducing more visual themes, while being based upon the more stable Windows NT kernel.

## Development

In 1998, Microsoft stated that there would be no version of Windows 9x after Windows 98. In May 1999, however, Microsoft released Windows 98 Second Edition, and then announced a new version of Windows 9x which was later revealed to be codenamed Millennium. Derived from the enterprise-oriented Windows 2000, Microsoft originally planned for Windows Neptune to be the first consumer version of Windows based on the NT kernel, though Neptune's release was postponed in favor of finalising project Millennium, which was released as Windows ME. Much of the work in developing Neptune was incorporated into Microsoft's next consumer release, the first NT-based one, Windows XP.

At least three beta versions of Windows ME were available during its development phase. On September 24, 1999, Microsoft announced that Windows Millennium Beta 1 was released. Windows Millennium Beta 2 was released on November 24, 1999 and added a couple of new features such as System File Protection and Game Options Control Panel. Several interim builds were released between Beta 1 and 2, and added features such as automatic updates and personalized menus. Beta 3 was released on April 11, 2000, and this version marked the first appearance of its final version startup and shutdown sounds (derived from Windows 2000), as the previous betas used Windows 98's startup and shutdown sounds. The final version boot screen was first featured in Pre-Beta 3 build 2470. The general availability date of Windows Millennium Edition was September 14, 2000. At launch time, Microsoft announced a time-limited promotion from September 2000 to January 2001 which entitled Windows 95 or Windows 98 users to upgrade to Windows ME for $59.95 instead of the regular retail upgrade price of $109.

Shortly after Windows ME was released to manufacturing on June 19, 2000, Microsoft launched a campaign-initiative to promote Windows ME in the U.S., which they dubbed the *Meet Me Tour*. A national partnered promotional program featured Windows ME, OEMs and other partners in an interactive multimedia attraction in 25 cities across the U.S. It was launched on September 14, 2000.

Compared with other releases of Windows, Windows ME had a short shelf-life of just over a year. Windows ME, along with Windows 2000, was eventually succeeded by the NT-based Windows XP, which was launched on August 24, 2001.

## New and updated features

### User interface

Windows ME featured the shell enhancements inherited from Windows 2000 such as personalized menus, customizable Windows Explorer toolbars, auto-complete in Windows Explorer address bar and Run box, Windows 2000 advanced file type association features, displaying comments in shortcuts as tooltips, extensible columns in Details view (IColumnProvider interface), icon overlays, integrated search pane in Windows Explorer, sort by name function for menus, *Places bar* in common dialogs for *Open* and *Save*, cascading Start menu special folders, some Plus! 95 and Plus! 98 themes, and updated graphics. The notification area in Windows ME and later supported 16-bit high color icons. The Multimedia control panel was also updated from Windows 98 SE. *Taskbar and Start Menu* options allowed disabling of the drag and drop feature and could prevent moving or resizing the taskbar, which was easier for new users.

### Hardware support improvements

* Faster boot times: Windows ME features numerous improvements for improving cold boot time, pre and post-logon boot times and time required for resuming from hibernation. Processing of real mode configuration files, `CONFIG.SYS` and `AUTOEXEC.BAT`, is bypassed at startup and essential real mode drivers like `HIMEM.SYS` and `SMARTDRV.EXE` are embedded into `IO.SYS`. The registry is loaded only once; for efficient loading, the registry is split into three files instead of two (`SYSTEM.DAT` and `USER.DAT`), with the new file `CLASSES.DAT` containing the contents of the hive `HKEY_CLASSES_ROOT` required for boot loaded initially. Plug and Play device enumeration is more parallelized than in Windows 98 SE. Boot time is not affected due to unavailability of a DHCP server or other network components. There are also optimizations to prevent boot slowdown due to BIOS POST operations.
* USB Human Interface Device Class: Generic support for 5-button mice is also included as standard and installing IntelliPoint allows reassigning the programmable buttons.
* Windows Image Acquisition: Windows ME introduced the Windows Image Acquisition API for a standardized method of allowing Windows applications to transparently and more easily communicate with image acquisition devices, such as digital cameras and scanners. WIA intended to improve the configuration and the user interface for interacting with scanners and such devices, (which were previously supported by the TWAIN standard) and simplify writing device drivers for developers. WIA also includes support for USB still image capture device classes such as scanners and cameras through the Picture Transfer Protocol.
* Improved power management and suspend/resume operations: The OEM version of Windows ME supports OS-controlled ACPI S4 sleep state (hibernation) and other power management features without manufacturer-supplied drivers.
* USB and FireWire support improvements: Windows ME is the only operating system in the Windows 9x series that includes generic drivers for USB mass storage devices and USB printers. Support for FireWire SBP-2 scanners and storage devices is also improved.
* The waveOut, DirectSound, and DirectShow APIs support non-PCM formats such as AC-3 or WMA over S/PDIF.

### Digital media

* Windows Movie Maker: This utility is based on DirectShow and Windows Media technologies to provide Microsoft Windows computer systems with basic video capture and edit capabilities. It provides users with the ability to capture, edit, and re-encode media content into the Windows MEdia format, a tightly compressed format which requires a minimal amount of storage space on the computer's hard disk, when compared to many other media formats.
* Windows Media Player 7: The new version of the Windows multimedia player software introduces jukebox functionality featuring the Media Library, support for CD burning, an integrated media encoder, and the ability to transfer music directly to portable devices. Another new feature is its radio tuner that can be used to search for and connect to radio stations over the internet. Users can also customize the look and feel of the user interface through interactive skins.
* Windows DVD Player: The software DVD player in Windows ME is a redesigned version of the one featured in Windows 98 SE which, unlike its predecessor, does not require a dedicated decoder card for DVD playback. Instead, it supports software decoding through a third-party decoder.
* Image Preview: In Windows ME, images can be viewed by using the Image Preview utility. It allows users to rotate an image, print or zoom in/out an image. Image Preview supports images with .`BMP`, .`DIB`, .`EMF`, .`GIF`, .`JPEG`, .`PNG`, .`TIF` and .`WMF` file formats. The *My Pictures* folder also integrates previewing images.
* Games: Windows ME includes version 7.1 of the DirectX API which introduced DirectPlay Voice, and also offers several new games: Internet Backgammon, Internet Checkers, Internet Hearts, Internet Reversi, Internet Spades. It also includes Spider Solitaire from Plus! 98 and Pinball from Plus! for Windows 95.

### Networking technologies

* Net Crawler: Windows ME introduced a net crawling feature which automatically searches out and creates shortcuts to network shares and printers in *My Network Places*. This can be controlled using the *Automatically search for network folders and printers* option. Shortcuts that are added by the net crawler but not detected again on the network in a reasonable time period are aged out and deleted.
* New TCP/IP Stack: Windows ME includes the Windows 2000 networking stack and architecture which was known to be more reliable, full-featured, stable and offered better performance. Support for networking over FireWire, improved infrared support, a network diagnostic troubleshooter and a new Home Networking wizard are also included.
* The Home Networking Wizard is designed to help users to set up a computer that is running Windows ME for use on a small home network. This includes setting up Internet Connection Sharing (ICS) on a computer running Windows ME so the computer can share a connection to the Internet with other computers on the home network.
* Dial-up Networking component was updated in Windows ME, and provides several enhancements while maintaining the desired features of prior releases of the operating system. The user interface had been reworked to provide all configurable parameters in one convenient location. The user interface now included three new tabs: *Networking*, *Security* and *Dialing*. To improve dial-up networking, Windows ME includes built-in support for the Connection Manager dial-up client. Using the Connection Manager Administration Kit (an optional networking component in Windows 2000 Server), network administrators can pre-configure and deploy dial-up networking connections, by means of a Connection Manager service profile, to Windows ME–based client machines.
* Network Driver Interface Specification (NDIS) version 5.0 for Windows ME was enhanced to provide programming interface parity with NDIS version 5.0 in Windows 2000. This means that the programming interfaces that the author of a network device driver uses are the same for both of these Windows platforms.
* Universal Plug and Play: Windows ME introduced support for Universal Plug and Play (UPnP). Universal Plug and Play and NAT traversal APIs can also be installed on Windows 98 and Windows 98 SE by installing the Windows XP Network Setup Wizard.

### System utilities

* System Restore: Windows ME introduced the "System Restore" logging and reversion system, which was meant to simplify troubleshooting and solve problems. It was intended to work as a rollback and recovery feature so that if the installation of an application or a driver adversely affected the system, the user could undo the installation and return the system to a previously working state. It does this by monitoring changes to Windows system files and the registry. System Restore protects only the operating system files, not documents, and therefore is not a substitute for a backup program.
* System File Protection: First introduced with Windows 2000 (as Windows File Protection), and expanding on the capabilities introduced with System File Checker in Windows 98, System File Protection aimed to protect system files from modification and corruption silently and automatically. When the file protection is in effect, replacing or deleting a system file causes Windows ME to silently restore the original copy. The original is taken from a hard drive backup folder (`%WinDir%\Options\Install`) or from the Windows ME installation CD, if the cached copy of files on the hard disk has been deleted. If no installation CD is in the drive, a dialog box alerts the user about the problem and requests that the CD be inserted. System File Protection is a different technology from System Restore and should not be confused with the latter. System Restore maintains a broad set of changed files including added applications and user configuration data stored repeatedly at specific points in time restored by the user, whereas System File Protection protects operating system files with no user input.
* System Configuration Utility allows users to manually extract and restore individual system files from the Windows ME setup files. It has also been updated with three new tabs called "Static VxDs", "Environment" and "International". The *Static VxDs* tab allows users to enable or disable static virtual device drivers to be loaded at startup, the *Environment* tab allows users to enable or disable environment variables, and the *International* tab allows users to set international language keyboard layout settings that were formerly set via the real mode MS-DOS configuration files. A *Cleanup* button on the *Startup* tab allows cleaning up invalid or deleted startup entries.
* System Monitor has been updated with a Dial-Up Adapter section. Users can now monitor items such as Connection Speeds, Bytes Received or Transmitted / Second.
* SCANDISK runs from within Windows upon an improper shutdown before the Windows Shell loads.
* Automatic Updates: The Automatic Updates utility automatically downloads and installs critical updates from the Windows Update Web site with little user interaction. It is set up to check Windows Update once every 24 hours by default. Users can choose to download which update they want, although high-priority updates must be downloaded and installed.
* Compressed Folders: Windows ME includes support for ZIP files through a shell extension known as Compressed Folders. Originally introduced in the Plus! 98 pack for Windows 98, this feature allows users to create, access and extract files from ZIP archives similar to a regular folder in Windows. The user can also restrict access to files with a password.
* A new *Help and Support* program has also been added, replacing the HTML Help-based documentation in Windows 2000 and Windows 98. The Help and Support Center is entirely HTML-based and takes advantage of a technology called Support Automation Framework (SAF), that can show support information from the internet, allows collecting data for troubleshooting via WMI and scripting and for third parties to plug into Windows Help and Support. Several other support tools also shipped with Windows ME.
* Windows ME also includes Internet Explorer 5.5, which supports a new Print Preview feature. It also shipped with the MSN Messenger Service.

### Accessibility features

* On-Screen Keyboard: Originally introduced with Windows 2000, a program called On-Screen Keyboard has been added, which makes it possible to input characters using the mouse instead of the keyboard. This feature is useful for computers that use a tablet as the primary pointing device or for accessibility purposes.
* The *Mouse* Control Panel incorporates IntelliPoint features, namely ClickLock (selecting or dragging without continuously holding down the mouse button), hiding the pointer while typing and showing it by pressing *Ctrl*.
* The cursor (system caret) can be set to a thicker width.
* Increased Active Accessibility support in utilities such as Calculator and Magnifier.

## Removed features

### Real mode DOS

Windows ME restricted support for real mode MS-DOS. As a result, `IO.SYS` in Windows ME disregards `CONFIG.SYS`, `COMMAND.COM` and `WIN.COM` and directly executes `VMM32.VXD`. In its default configuration the system would neither boot into an MS-DOS command prompt nor exit to DOS from Windows; real mode drivers such as `ANSI.SYS` could not be loaded and older applications that require real mode could not be run. Microsoft argued that the change improved the speed and reliability of the boot process.

In Windows ME, the `CONFIG.SYS` and `AUTOEXEC.BAT` files are used only to set global environment variables. The two files (if present) are scanned for settings relating to the environment variables, and any other commands present are removed into a Windows registry key (see below). The two files thus contain only settings and preferences which configure the "global environment" for the computer during the boot phase or when starting a new virtual DOS machine (VDM).

To specify or edit other startup values (which, in Windows 98, would be present in the `AUTOEXEC.BAT` file) the user must edit the following Windows registry key:

`HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SessionManager\Environment`
For troubleshooting and crash recovery, both the Windows ME CD-ROM and the Windows ME startup disk (a user-createable floppy disk, known as the Emergency Boot Disk (EBD)) allowed booting into real mode MS-DOS.

It is possible to restore real mode DOS functionality through various unofficial means. Additionally, a registry setting exists that re-enables the "Restart in MS-DOS mode" option in the shutdown dialog box.

### Other components

Unlike past versions of Windows 9x, Windows ME was entirely aimed at home users, and thus had certain enterprise-oriented features removed. Several features of its predecessors did not work or were officially unsupported by Microsoft on Windows ME, including Automated Installation, Active Directory client services, System Policy Editor, Personal Web Server and ASP. These features were supported on its predecessors, Windows 98 and Windows 95. A Resource Kit publication, targeted towards system administrators, was never published for Windows ME.

Other features that were removed or never updated to work with Windows ME included Microsoft Fax, QuickView and DriveSpace, as well as the GUI FAT32 conversion tool. Several Windows Explorer commands were also removed in Windows ME.

## Reception

Windows ME was heavily panned by many users and critics, mainly due to stability issues. Due to its many bugs and glitches, Windows ME is considered one of the worst operating systems of all time. A *PC World* article dubbed Windows ME the "Mistake Edition" and placed it 4th in their "Worst Tech Products of All Time" feature in 2006. The article states: "Shortly after Me appeared in late 2000, users reported problems installing it, getting it to run, getting it to work with other hardware or software, and getting it to stop running." Consequently, most home users remained with Windows 98 Second Edition, while some moved to Windows 2000 despite the latter being enterprise-oriented.

System Restore suffered from a bug in the date-stamping functionality that could cause System Restore to date-stamp snapshots that were taken after September 8, 2001 incorrectly. This could prevent System Restore from locating these snapshots and cause the system restore process to fail. Microsoft released an update to fix this problem.

Byron Hinson and Julien Jay, writing for ActiveWin, took an appreciative look on the operating system. On the removal of real mode DOS, they had noted "The removal of DOS has clearly made a difference in Windows ME in terms of stability (far less Blue Screens of Death are seen now) and booting speed has greatly increased." In a recommendation of the operating system upgrade for users of Windows 95 and 98, they had stated "If Windows ME isn't a revolutionary OS it's clear that Microsoft has focused its efforts to make it more user-friendly, stable and packed full of multimedia options. The result is great and the enhancements added are really worth the wait." The new features that Windows ME introduced were also praised and have since remained part of subsequent Windows generations.

Along with Windows 2000 from the NT family, Windows ME was the last version of Windows that lacked product activation.

## Product life cycle

Microsoft planned to stop its support for Windows ME on December 31, 2004. However, in order to give customers more time to migrate to newer Windows versions, particularly in developing or emerging markets, Microsoft decided to maintain support until July 11, 2006. Support for Windows 98 also ended on this date. Microsoft ended support for these products because the company considers them obsolete and running these products can expose users to security risks. Windows ME also contained the Microsoft Java Virtual Machine, which caused it as well as Windows 98 and Windows 98 SE to be pulled from the Microsoft Developer Network at the end of 2003.

In 2011, Microsoft removed the update website for Windows ME (the updates site for Windows 98 and Windows 98 SE was also terminated that year).[*citation needed*] Microsoft announced in July 2019 that the Microsoft Internet Games services on Windows ME and Windows XP would end on July 31, 2019 (and for Windows 7 on January 22, 2020).

## Upgradeability

Windows ME could have its components upgraded or have new components installed up to the following versions:

* Internet Explorer 6 SP1 and Outlook Express 6 SP1
* Windows Media Player 9 Series
* MSN Messenger 7.0
* Windows Installer 2.0
* DirectX 9.0c (the latest compatible runtime is from October 2007.)
* Microsoft .NET Framework up to and including version 2.0 (2.0 SP1 and higher versions are not supported.)
* Microsoft Visual C++ 2005 runtime
* Text Services Framework
* Several other components such as MSXML 3.0 SP7, Microsoft Agent 2.0, NetMeeting 3.01, MSAA 2.0, ActiveSync 3.8, WSH 5.6, Microsoft Data Access Components 2.81 SP1, WMI 1.5 and Speech API 4.0.
* Office XP was the last version of Microsoft Office to be compatible with Windows ME.
* The Microsoft Layer for Unicode can be installed to allow certain Unicode applications to run on the operating system.

## System requirements

 CPU
 Memory
 Free space
 Media
 Display
 Sound hardware
* Speakers or headphones
 Network
 Input device(s)

Windows ME is not designed to handle more than 512 MB of RAM by default. Systems with larger RAM pools may lose stability; however, depending on the hardware and software configuration, it is sometimes possible to manually tweak the installation to continue working with somewhat larger amounts of RAM as well. Systems with 1.5 GB of RAM or more may reboot continuously during startup. The /nm setup switch can be used at the DOS command line to bypass the minimum requirements, allowing for installation on a CPU as low as the 16 MHz 80486SX.
