Microsoft Windows 7

Everything you need to know about Windows 7

Microsoft Windows 7 was one of the most successful versions of the Windows operating system line ever released.

As of January 2020, Microsoft is no longer supporting Windows 7. We recommend upgrading to Windows 10 or Windows 11 to continue receiving security updates and technical support.

Windows 7 Release Date

Windows 7 was released to manufacturing on July 22, 2009. It was made available to the public on October 22, 2009.

It's preceded by Windows Vista, and succeeded by Windows 8.

Windows 11 is the latest version of Windows, released in 2021.

Windows 7 Support

The Windows 7 end-of-life was on January 14, 2020. This was when Microsoft discontinued technical support and quit supplying Windows 7 users with software updates and security fixes through Windows Update.

On January 14, 2020, Microsoft also ended support for the following for Windows 7 users:

  • Internet Explorer
  • Games like Internet Checkers and Internet Backgammon
  • Microsoft Security Essentials platform (signature updates remain)

Although Windows 7 has been discontinued, it can still be activated and installed on new computers. If you're a Microsoft 365 user, Microsoft continued to provide security updates for Microsoft 365 through January 2023, but not feature updates.

It's recommended that you install Windows 11 to continue getting security and feature updates for Windows.

The Best Version of Windows 7 For You

Windows 7 Ultimate is the, well, ultimate version of Windows 7, containing all the features available in Professional and Home Premium, plus BitLocker technology. Windows 7 Ultimate also has the largest language support.

Windows 7 Professional (aka, Windows 7 Pro) contains all the features available in Home Premium, plus Windows XP Mode, network backup features, and domain access, making this the right choice for medium and small business owners.

Windows 7 Home Premium is the version designed for the standard home user, including all the non-business bells and whistles that make Windows 7...well, Windows 7! This tier is also available in a "family pack" that allows installation on up to three separate computers. Most Windows 7 licenses allow installation onto only one device.

Windows 7 Enterprise is designed for large organizations. Windows 7 Starter is only available for pre-installation by computer makers, usually on netbooks and other small form-factor or lower-end computers. Windows 7 Home Basic is only available in some developing countries.
