History First version of Microsoft Windows hit the market in 1983. Windows 1.0 was not an operating system. It was a graphical user interface that worked with an existing OS called MS-DOS. Version 1.0 didn't look much like newer versions either. Graphics were simpler and used fewer colors.

History Cont..:

History Cont.. Windows has changed considerably in the last 20 years. Microsoft has released numerous full-fledged versions of the operating system.

Newest Windows :

Newest Windows Microsoft's newest version of its operating system is Windows Vista. For many users, upgrading to Vista won't seem as dramatic as when they upgraded from 3.1 to Windows 95. But Windows Vista has a number of new features, both in the parts that you can see and the parts that you can't.

New Features: User Account Control:

New Features: User Account Control Goal: Allow businesses to move to a better-managed desktop and consumers to use parental controls Make the system work well for standard users Allow standard users to change time zone and power management settings, add printers, and connect to secure wireless networks High application compatibility Make it clear when elevation to admin is required and allow that to happen in-place without logging off High application compatibility with file/registry virtualization Administrators use full privilege only for administrative tasks or applications User provides explicit consent before using elevated privilege

Why: User Account Control:

Why: User Account Control OS is at risk from malware when user is running as Administrator Ease with which malware can self-install Privilege elevation through security holes in software Extent of damage caused by malware is potentially greater Accidental damage caused by user

How: User Account Control:

How: User Account Control With Windows Vista, all users run as Standard User by default, including members of Admin group Only true for interactive logins; services continue to run as before in Windows XP Two tokens are created at logon (split token) Standard User Token Administrator SID set as Deny Only (can still be used to deny access, but not to grant) Runs with medium integrity level (IL) Most privileges removed Administrator Token Administrator SID has all rights assigned Runs with high integrity level (IL) All privileges are present

How: User Account Control (cont.):

How: User Account Control (cont.) Standard User Token is used until explicit consent is given, then Administrator Token is used (Consent UI) Supporting feature: Unnecessary Administrator checks (in XP) have been removed Example: Change time zone
