The Start Menu is back and a speech assistant Cortana is available. Windows CE officially known as Windows Embedded Compact , is an edition of Windows that runs on minimalistic computers, like satellite navigation systems and some mobile phones. The OEMs and device makers can modify and create their own user interfaces and experiences, while Windows CE provides the technical foundation to do so.
Windows CE was the core from which Windows Mobile was derived. Windows Phone 8 however, is based on the same NT-kernel as Windows 8. Xbox OS is an unofficial name given to the version of Windows that runs on Xbox consoles. Before Microsoft has used a proprietary SourceDepot Version Control system which couldn't keep up with size of Windows.
In Microsoft announced that it would start using Git, an open source version control system created by Linus Torvalds and in May of they reported that has completed migration into the Git repository. Because of its large, decades-long history, however, the Windows codebase is not especially well suited to the decentralized nature of Linux development that Git was originally created to manage.
Market share overview As a percentage of desktop and laptop systems, [76] according to StatCounter data from June [77]. Use of the latest version Windows 10 has exceeded Windows 7 globally since early Including personal computers of all kinds e. Those statistics do not include servers including so-called cloud computing, where Microsoft is known not to be a leader, with Linux used more than Windows , as Net Applications and StatCounter use web browsing as a proxy for all use.
Consumer versions of Windows were originally designed for ease-of-use on a single-user PC without a network connection, and did not have security features built in from the outset. These design issues combined with programming errors e. In June , Bruce Schneier's Counterpane Internet Security reported that it had seen over 1, new viruses and worms in the previous six months. Microsoft releases security patches through its Windows Update service approximately once a month usually the second Tuesday of the month , although critical updates are made available at shorter intervals when necessary.
While the Windows 9x series offered the option of having profiles for multiple users, they had no concept of access privileges, and did not allow concurrent access; and so were not true multi-user operating systems. In addition, they implemented only partial memory protection. They were accordingly widely criticised for lack of security. The Windows NT series of operating systems, by contrast, are true multi-user, and implement absolute memory protection. However, a lot of the advantages of being a true multi-user operating system were nullified by the fact that, prior to Windows Vista, the first user account created during the setup process was an administrator account, which was also the default for new accounts.
Though Windows XP did have limited accounts, the majority of home users did not change to an account type with fewer rights — partially due to the number of programs which unnecessarily required administrator rights — and so most home users ran as administrator all the time. Windows Vista changes this [89] by introducing a privilege elevation system called User Account Control.
When logging in as a standard user, a logon session is created and a token containing only the most basic privileges is assigned.
In this way, the new logon session is incapable of making changes that would affect the entire system. When logging in as a user in the Administrators group, two separate tokens are assigned. The first token contains all privileges typically awarded to an administrator, and the second is a restricted token similar to what a standard user would receive. User applications, including the Windows shell, are then started with the restricted token, resulting in a reduced privilege environment even under an Administrator account.
When an application requests higher privileges or 'Run as administrator' is clicked, UAC will prompt for confirmation and, if consent is given including administrator credentials if the account requesting the elevation is not a member of the administrators group , start the process using the unrestricted token.
Leaked documents published by WikiLeaks, codenamed Vault 7 and dated from to , detail the capabilities of the CIA to perform electronic surveillance and cyber warfare, [91] such as the ability to compromise operating systems such as Microsoft Windows.
In August , computer experts reported that the BlueKeepsecurity vulnerability, CVE, that potentially affects older unpatched Microsoft Windows versions via the program's Remote Desktop Protocol, allowing for the possibility of remote code execution, may now include related flaws, collectively named DejaBlue , affecting newer Windows versions i.
These global groups then hold other groups or users depending on different Windows versions used. This system varies from other vendor products such as Linux and NetWare due to the 'static' allocation of permission being applied directly to the file or folder. Owing to the operating system's popularity, a number of applications have been released that aim to provide compatibility with Windows applications, either as a compatibility layer for another operating system, or as a standalone system that can run software written for Windows out of the box.
