Criticism of Windows XP

Criticism of Windows XP deals with issues with security, performance and the presence of product activation errors that are specific to the Microsoft operating system Windows XP.

Security issues

Windows XP has been criticized for its vulnerabilities due to buffer overflows and its susceptibility to malware such as viruses, trojan horses, and worms. Nicholas Petreley for The Register notes that "Windows XP was the first version of Windows to reflect a serious effort to isolate users from the system, so that users each have their own private files and limited system privileges."[1] However, users by default receive an administrator account that provides unrestricted access to the underpinnings of the system. If the administrator's account is compromised, there is no limit to the control that can be asserted over the PC. Windows XP Home Edition also lacks the ability to administer security policies and denies access to the Local Users and Groups utility.

Microsoft stated that the release of security patches is often what causes the spread of exploits against those very same flaws, as crackers figure out what problems the patches fix and then launch attacks against unpatched systems. For example, in August 2003 the Blaster worm exploited a vulnerability present in every unpatched installation of Windows XP, and was capable of compromising a system even without user action. In May 2004 the Sasser worm spread by using a buffer overflow in a remote service present on every installation. Patches to prevent both of these well-known worms had already been released by Microsoft. Increasingly widespread use of Service Pack 2 and greater use of personal firewalls may also contribute to making worms like these less common.[2]

Many attacks against Windows XP systems come in the form of trojan horse e-mail attachments which contain worms. A user who opens the attachment can unknowingly infect their own computer, which may then e-mail the worm to more people. Notable worms of this sort that have infected Windows XP systems include Mydoom, Netsky and Bagle. To discourage users from running such programs, Service Pack 2 includes the Attachment Execution Service which records the origin of files downloaded with Internet Explorer or received as an attachment in Outlook Express. If a user tries to run a program downloaded from an untrusted security zone, Windows XP with Service Pack 2 will prompt the user with a warning.

Spyware and adware are a continuing problem on Windows XP and other versions of Windows. Spyware is also a concern for Microsoft with regard to service pack updates; Barry Goff, a group product manager at Microsoft, said some spyware could cause computers to freeze up upon installation of Service Pack 2.[3] In January 2005, Microsoft released a free beta version of Windows Defender which removes some spyware and adware from computers.

Windows XP offers some useful security benefits, such as Windows Update, which can be set to install security patches automatically, and a built-in firewall. If a user doesn't install the updates for a long time after the Windows Update icon is displayed in the toolbar, Windows will automatically install them and restart the computer on its own. This can lead to the loss of unsaved data if the user is away from the computer when the updates are installed. Service Pack 2 enables the firewall by default. It also adds increased memory protection to let the operating system take advantage of new No eXecute technology built into CPUs such as the AMD64. This allows Windows XP to prevent some buffer overflow exploits.

On April 8, 2014, extended support of Windows XP ended. As this means that security vulnerabilities are no longer patched, the general advice given by both Microsoft and security specialists is to no longer use Windows XP.

Antitrust concerns

In light of the United States v. Microsoft Corp. case which resulted in Microsoft being convicted for illegally abusing its operating system monopoly to overwhelm competition in other markets, Windows XP has drawn fire for integrating user applications such as Windows Media Player and Windows Messenger into the operating system, as well as for its close ties to the Windows Live ID (now Microsoft account) service.

In 2001, ProComp – a group including several of Microsoft's rivals, including Oracle, Sun, and Netscape – claimed that the bundling and distribution of Windows Media Player in Windows XP was a continuance of Microsoft's anticompetitive behavior[4] and that the integration of Windows Live ID (at the time Microsoft Passport) into Windows XP was a further example of Microsoft attempting to gain a monopoly in web services.[5] Both of these claims were rebutted by the Association for Competitive Technology (ACT) and the Computing Technology Industry Association (CompTIA), both partially funded by Microsoft.[6]

Backward compatibility

Migrating from Windows 9x to XP can be an issue for users dependent upon MS-DOS. Although XP comes with the ability to run DOS programs in a virtual DOS machine, it still has trouble running many old DOS programs. This is largely because it is a Windows NT system and does not use DOS as a base OS, and because the Windows NT architecture is different from Windows 9x.[14] Some DOS programs that cannot run natively on XP, notably programs that rely on direct access to hardware, can be run in emulators, such as DOSBox or virtual machines, like VMware, Virtual PC, or VirtualBox. This also applies to programs that only require direct access to certain common emulated hardware components, like memory, keyboard, graphics cards, and serial ports. With DOS emulators, 32-bit versions of Windows XP can run almost any program designed for any previous Microsoft operating system. Only 64-bit versions of XP have major backward-compatibility issues. This is because old 16-bit Windows programs require a tool called NTVDM, which is only present in the 32-bit version of the OS. However, this is true of every version of Windows that comes in both 32-bit and 64-bit versions, and it is not specific to XP; additionally, virtual machine software such as VirtualBox can run 16-bit DOS and Windows programs even on 64-bit versions of Windows.

Product activation and verification

Default theme

Windows XP's default theme, Luna, was criticized by some users for its childish look.[21][22]
