With Windows 8, Microsoft is making one of the biggest upgrades to its
PC operating system. For one, it will replace the Start Menu with a
Start Screen - with tiles that contain shortcuts to applications -
similar to the Metro interface seen on its Windows Phone 7 OS.
It will also be introducing the Ribbon interface - first seen in Office
2007 - to Windows Explorer. It will launch a store for the new
Metro-style apps that Windows 8 will support.
But the changes to
the new OS are not just cosmetic. Windows 8 has been designed ground-up
to support ARM processors - the chips used in tablets - apart from the
X86 processors from Intel and AMD. This means the same operating system
will be available on desktops, laptops and slates/tablets. And
regardless of the machine's form factor, whether tablet or PC, this new
OS promises a slew of brand new features that seem just as compelling to
power users as they are enticing to newbies.
Picture passwords
It can be rather cumbersome to enter long, complex passwords on
touchscreen devices such as tablets. Yet, having a strong passcode is
important, especially on portable devices. To allow for better
security, Windows 8 utilizes a new system that incorporates pictures and
gestures in user authentication. It's a simple concept: Users will
first need to select an image on which to perform a gesture. The gestures could be tapping on something in the picture, encircling something, or drawing a line between two points.
A "password" would then comprise any combination of these three. Since
you can pick any photo to perform the gesture on, these actions could be
based on the image, such as tapping someone's nose, encircling a book,
or drawing a line along the edge of an object.
Windows to go
Portable applications are a growing trend. Already, you can run software
such as web browsers, word processors, image editors etc from a pen
drive (so you can carry your favourite software to use on almost any
computer).
With Windows 8, you will even be able to take the
entire operating system with you. Enterprise versions of the OS will be
capable of running off a flash drive or portable harddrive. Since your
Windows environment pretty much makes your computer yours, you will - in
effect - be carrying your entire PC around without having to lug bulky
hardware.
Refresh and reset
After
an extended period of using Windows, you will often find a noticeable
decrease in performance - as applications are installed, and then
uninstalled, remnants of these programs start to build up and cause
performance issues. The best solution in such cases is to
reinstall the OS and migrate your data to the new copy. But this
solution has been needlessly difficult till now - and usually, only
expert users resort to it. Windows 8 will change all that...
The new OS will have two options, Refresh and Reset, to tackle this
problem. Reset, as its name suggests, resets your installation to its
initial state. It deletes all your personal data and software, leaving a
fresh Windows 8 computer that you can even hand over to someone else.
Refresh is a less drastic measure. It retains your personal data, customisations and settings, and reinstalls Windows in-place.
After this procedure you can log into the same old account, and see all
your documents intact. Your desktop apps will be gone, but a list of
those will be saved so you can remember which ones you need to
reinstall. If you want to refresh Windows to a customised state (instead of a blank slate), you can do that as well.
Better automatic updates

With Windows 8, you will no longer be harassed by those frequent
15-minute warnings that inform you that your system has been updated and
needs to be restarted. With the new OS, Windows Update (WU) will
consolidate all the restarts in a month into one single restart.
With this new feature, it will not matter when the updates are
released, since these restarts will wait till the month's security
release. In case of a critical update, however, WU will download,
install and restart automatically. But this will happen only
when the security threat is dire enough - and there is no chance of
losing the user's data. That means the restarts will not happen if you
are not at your PC, if you have applications running in the background,
or if there is potentially unsaved work.
Protection from malware
Windows 8 boot process will support a new built-in mechanism called
Secure Boot, which will ensure that the system being booted has not been
tampered by malware. Another anti-malware feature in Windows 8 is a
technology it borrows from Internet Explorer (IE), called SmartScreen. SmartScreen
checks URLs entered in the browser against a database of malware links,
and in IE9 this feature was extended to downloaded files. The
browser checks the "reputation" of the file you download and warns you
if the file is unknown and downloaded by very few people. Now instead of
being an IE-only feature, this technology is baked into Windows, and it
will check files downloaded using any browser or program.
File management improvements
The copying mechanisms that Windows currently uses can be quite
inefficient. Not only are the 'copy time' estimates frustratingly
erroneous, but even basic features such as pausing a transfer are
absent. Windows 8 rectifies this and a number of other issues with improvements in its file management system.
First
of all, if you are running multiple file operations on Windows 8, it
consolidates them all into a single window showing all transfers.
Secondly, individual operations can be paused or cancelled. And while
the basic Copy operation window is simplified, there is a new detailed
view that offers a lot more, including the current speed, and a graph of
how that speed has changed over time. Conflicts while copying
are also managed better. If while copying from one folder to another
Windows detects multiple conflicting files, it can show you a detailed
list of files in both the folders and the differences between them,
along with the option to skip files that are exactly the same on both
sides. Windows 8 also makes it possible for you to access files in an ISO file without burning it to a disc.
Logging in via Windows Live ID
A Windows Live ID gives you access to Microsoft cloud services such as
Hotmail for email, Office Web for online document creation and
collaboration, SkyDrive for online file storage, Live messenger for chat
etc. In Windows 8, Microsoft will let you log into your computer with
this ID.
It might seem odd to log into your own PC with an
online account, however, Microsoft offers a number of advantages for
such users. First, such accounts will automatically be synchronised with
Microsoft's servers. Many of your settings such as your wallpaper,
mouse settings, Explorer settings, Internet Explorer history and
favourites, spell-check dictionaries and a number of other settings will
be available on any computer, you log into with this account - and if
you make a change on one computer it will be reflected to all other
computers. Metro-style applications purchased from the Windows
Store will also be available on all your computers, along with their
settings. An eBook reader, for instance, could let you start reading a
book on one Windows 8 device and continue on another. IE10 already
supports this feature and will keep browsing sessions in sync across
computers.
