On-Screen Keyboard Portable is a handy way to bring your settings for the Windows’ built-in On-Screen Keyboard with you from PC to PC. It will remember your hover preferences and other options and provides an easy way to launch it right from the PortableApps.com Menu. For earlier operating systems that lack a built-in on-screen keyboard (Windows 95/98/Me) it even includes a simple virtual keyboard that, while lighter on accessibility features, is still useful.
While on-screen keyboards offer protection against hardware keyloggers, they do not offer protection against software keyloggers (which are far more common). They are primarily intended as an accessibility tool or for alternate means of text entry (pen-based computing, etc).
If you’re using the PortableApps.com Menu, to start your portable app, just click its icon within the menu. If you’re running it standalone, browse to the directory you installed it to and, in the [AppName]Portable directory, double-click the [AppName]Portable.exe file.
