Pre-installed software (also known as bundled software)〔 is software already installed and licensed on a computer or smartphone bought from an original equipment manufacturer (OEM).〔("Pre-installed on a new computer" ), a Microsoft article〕 The operating system is usually pre-installed, but because it is a general requirement, this term is used for additional software apart from the bare necessary amount, usually from other sources (or the operating system vendor). Unwanted pre-installed software (also known as crapware) can include major security vulnerabilities, like Superfish, which installs a root certificate to inject advertising into encrypted Google search pages, but leaves computers vulnerable to serious cyberattacks that breach the security used in banking and finance websites. Some free download websites use unwanted software bundling that similarly installs unwanted software. ==Unwanted software== Often new PCs come with pre-installed software which the manufacturer was paid to include but is of dubious value to the purchaser. Most of these programs are included without the user's knowledge, and have no instructions on how to opt-out or remove them.〔(【引用サイトリンク】website=https://www.malwarebytes.org/pup/ )〕 A Microsoft executive mentioned that within the company these applications were dubbed craplets (a portmanteau of ''crap'' and ''applet''). He was saying that the experience of people buying a new Windows computer can be damaged by poorly designed, uncertified third-party applications installed by vendors. He stated that the antitrust case against Microsoft prevented the company from stopping the pre-installation of these programs by OEMs. Walt Mossberg, technology columnist for ''The Wall Street Journal'', condemned "craplets" in two columns published in April 2007, and suggested several possible strategies for removing them.〔 According to Ars Technica, most unwanted programs are installed by OEMs who receive payment from the authors of the software. At the 2007 Consumer Electronics Show, Dell defended this practice, stating that it keeps costs down, and implying that systems might cost significantly more to the end user if these programs were not pre-installed. Some system vendors and retailers will offer, for an additional charge, to remove unwanted pre-installed software from a newly purchased computer; retailers, in particular, will tout this service as a "performance improvement." In 2008, Sony Corporation announced a plan to charge end users US$50 for the service; Sony subsequently decided to drop the charge for this service and offer it for free after many users expressed outrage. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「preinstalled software」の詳細全文を読む スポンサード リンク
