Although MS Windows (in its various versions) is at present the most
popular OS (Operating System) in personal computers, after years of
consecutive improvements there are still various issues which need to be
improved, which include for example issues of efficiency, comfort, and/or
reliability. The present invention tries to solve the above problems in
new ways that include considerable improvements over the prior art.
Preferably the system allows for example a "Reset" function, which means
that preferably an Image of the state of the OS (including all loaded
software) is saved immediately after a successful boot on the disk or
other non-volatile memory and is preferably automatically updated when
new drivers and/or software that change the state after a boot are added,
so that if the system gets stuck it can be instantly restarted as if it
has been rebooted. Other features include for example solving the problem
that the focus can be grabbed while the user is typing something,
allowing the user to easily define or increase or decrease the priority
of various processes or open windows, a powerful undo feature that can
include preferably even any changes to the hard disk, improved undo
features in word processing, improved file comparison features, being
able for example to track changes retroactively, improved backup
features, and many additional improvements. The application covers also
improvements that are related for example to Word processing (since for
example in Microsoft Windows, Word behaves like an integral part of the
system) and things that are related to the user's Internet surfing
experience (This is important since for example in Microsoft Windows,
Internet Explorer is practically an integral part of the OS). The
invention deals also with some preferable improvements in the performance
of the hard disk.
