Fixes to Windows 98 to resolve the Year 2000 problem were distributed using Windows Update in December 1998. Security fixes for Outlook Express, Internet Explorer and other programs appeared later, as did access to beta versions of upcoming Microsoft software, e.g.
The initial focus of Windows Update was free add-ons and new technologies for Windows. Windows 95 and Windows NT 4.0 were retroactively given the ability to access the Windows Update website and download updates designed for those operating systems, starting with the release of Internet Explorer 4. Windows Update was introduced as a web app with the launch of Windows 98 and offered additional desktop themes, games, device driver updates, and optional components such as NetMeeting. The Windows Update web app, version 4, in Windows Me In Windows 10 and Windows 11, the use of Windows Update is mandatory, however, the software agreement states that users may stop receiving updates on their device by disconnecting their device from the Internet. System administrators can configure Windows Update to install critical updates for Microsoft Windows automatically, so long as the computer has an Internet connection. Microsoft routinely releases updates on the second Tuesday of each month (known as the Patch Tuesday), but can provide them whenever a new update is urgently required to prevent a newly discovered or prevalent exploit. Cumulative updates were introduced with Windows 10 and have been backported to Windows 7 and Windows 8.1. Cumulative updates are updates that bundle multiple updates, both new and previously released updates. Security updates or critical updates mitigate vulnerabilities against security exploits against Microsoft Windows. The service provides several kinds of updates. Starting with Windows Vista, the primary client component became Windows Update Agent, an integral component of the operating system.
For a decade, the primary client component of the service was the Windows Update web app that could only be run on Internet Explorer. The latter is available to business editions of Windows 10 and permits postponing updates or receiving updates only after they have undergone rigorous testing.Īs the service has evolved over the years, so has its client software. The former expands the core service to include other Microsoft products, such as Microsoft Office and Microsoft Expression Studio. Since its inception, Microsoft has introduced two extensions of the service: Microsoft Update and Windows Update for Business. The service delivers software updates for Windows, as well as the various Microsoft antivirus products, including Windows Defender and Microsoft Security Essentials.
Windows Update is a Microsoft service for the Windows 9x and Windows NT families of operating system, which automates downloading and installing Microsoft Windows software updates over the Internet.
