IntelliType
Microsoft IntelliType is the brand driver for Microsoft's series of computer keyboards. Microsoft releases versions for both Windows and (as of version 10.15 Microsoft IntelliType no longer installs on ). It has been succeeded by Microsoft Mouse and Keyboard Center, which combines IntelliType with IntelliPoint. IntelliType supports all known Microsoft keyboards (including those that are shipped as parts of desktop sets, as well as entertainment keyboards – i.e. those that are intended for Media center). However, advanced features may only be available on certain models (the users select their keyboard's type inside the program to access that keyboard type 's specific button selection). Supported keyboards. Note: Version 8.0 and above dropped PS/2 support for the following list. As even adapters can't assist, Microsoft keeps version 7.1 as an offered download for users who still own keyboards with PS/2 connectors (instead of USB). Special features. If the keyboard has multimedia buttons, the user can define them to run any program or action. On-screen indication of NumLock/CapsLock toggling with some keyboards. On-screen indication of volume level when level is changed. Limitations. While the user could always define special keys (and multimedia keys, if such exist), it was  only possible since version 6.3 to define them not just globally but also per application. Version 6.2 forced the user to constantly check for updates by installing and launching the file "dpupdchk.exe" in the background. It must stay in the background for the control panel's settings to launch (although it could be avoided by renaming the file to something else). Version 6.3 fixed this behavior by only making it an opt-in option during the installation. Version 7.0 and later in Windows 7 64-bit has recently been proven to disable the media keys (Play/Pause, Next, Previous, Stop ) for third-party media players such as iTunes and Media Jukebox when they are not the primary window of focus. Some workaround exists: This behavior continues to be an issue as of Version 8.
