been released as a test version for keen users to try.

4. Windows 7
Windows 7 is a personal computer operating
system developed by Microsoft, a version of
Windows NT. Development of Windows 7 occurred
as early as 2006 under the codename
"Blackcomb." Windows 7 was released to
manufacturing on July 22, 2009, and became
generally available on October 22, 2009, less than
three years after the release of its
predecessor, Windows Vista.

5. Features of Windows 7
1. Home group
2. Windows Live Essentials
3. Jump Lists
4. Improved gadgets
5. Performance Improvements

7. Windows 8
Windows 8 is a personal computer operating
system developed by Microsoft as part of the Windows
NT family of operating systems. Development of
Windows 8 started before the release of its
predecessor, Windows 7, in 2009. The operating
system was released to manufacturing on August 1,
2012, and was released for general availability on
October 26, 2012. Windows 8 is a totally new version
of Windows that, in addition to the traditional desktop,
also includes a new-style interface for use with touch
screens.

8. Features of Windows 8
1. Windows 8 touch
2. Windows 8 Start screen
3. Windows 8 charms
4. Windows 8 Search and Social
5. Windows Store
6. Windows 8 cloud integration

10. Differences between Windows 7 & Windows 8

11. Differences between Windows 7 & Windows 8
1. Hardware Requirements

12. 2. Structure
Different from Windows 7, which was intended
to be a more focused and have a desktop similar
to the previous versions of windows, Windows 8
has been "restructured from the chipset to the
user experience" to relate more with the user. It
features the Metro interface which gives users a
brand-news experience.

13. The most immediate and fundamental
difference between Windows 7 and Windows 8
is the main interface. The Metro interface is the
default home screen for Windows 8, and
features a series of colorful tiles, each offering
access to a discrete application. Each offers live
information, so you can see how many emails
are in your inbox, for example, without having to
open an application.

15. 4. Search
o In Windows 8, available
through Search charm +
Start Screen
o Start typing and the results
are on screen for programs
and files.
o In Windows 7, we were
required to first click on
Start button and then click
on search bar.
o Afterwards we can search
what we require.

16. 5.Windows Store and Apps
Windows 8 is an online shop front that is stuffed
with full Windows apps - each designed to run
on x86 Windows PCs, laptops and tablets, as
well as ARM tablets and smart phones. Native
apps included with Windows 8 include the Mail
email app, a calendar app and much improved
contacts app called People. There's Photos,
Music, IE, Weather, Finance, Sports and so on.
On the other hand, Windows 7 OS is missing all
these features.

17. 6. Core Upgrades
Windows 8 boots up faster and the OS itself
consumes less RAM and CPU cycles than
Windows 7. For mobile users this means more
battery life and snappier performance but for
Desktop users, this means Windows 8 is simply
faster than Windows 7.

18. 7. Speed and Performance
There are number of speed and
performance tests so as to compare
Windows 8 with Windows 7.Some
of them are as follows :-
7.1. Startup Time
Windows 8 Starts Up faster than
Windows 7. Windows 8 took 18
seconds while windows 7 took 27
seconds. Calculated difference is 8
seconds.

19. 7.2. Shutdown Time
A similar improvement is seen when measuring
shutdown time. Windows 8 took 8 seconds versus
the 12 seconds in windows 7. Calculated difference
is 4 seconds.
7.3. Wake-up From Sleep
Windows 8 shows a marked improvement here as
well. However we still thought 10 seconds was too
long. We then tested Windows 8 using our SSD and
the exact same 10 second window was repeated.
While windows 7 took 13 seconds.
7.4. 3D Graphics Performance
3Dmark 11 is used primarily to measure 3D
graphics performance – meaning graphics card
drivers play a vital role here. Still, the performance
was very similar on both operating systems, though
the more mature Windows 7 was slightly faster.

20. 7.5. Microsoft Excel
Comparing Windows 8 armed with the new Office
2013 suite we found that it was 10% faster when
running our Excel test against Windows 7 using Office
2010.
7.6. Transferring Multiple Files Together
When transferring thousands of files we found that
Windows 7 and Windows 8 offer the same
performance.
7.7. Different Browsers with Windows 7 and Windows 8
As you can see, the desktop version of the IE10
browsers on Windows 8 delivered virtually the same
performance as IE9 on Windows 7. Chrome works
better in Windows 8 in comparison with Firefox running
on identical Windows 8 computer. Also both Mozilla
Firefox and Google Chrome perform faster in Windows
8 than Windows 7. Internet Explorer works very slowly
in all versions of windows.

21. Due to the inclusion of UEFI (which is basically
like a very light-weight operating system that
then loads Windows), there is also a boot-level
malware scanner that will prevent your
computer from booting if a USB thumb drive is
infected. There’s also Secure Boot, which stops
the system from loading if any core system files
have been altered. So, Windows 8 is more
secure in comparison to windows 7.

22. Improved power management in Windows 8
takes a three-pronged approach. The
introduction of the Metro app model; idle
hygiene; and runtime device power
management.
Windows 7 requires more power consumption
in comparison to windows 8.

23. • Only lists currently running applications.
• Doesn’t prompt users to confirm when ending a task
• For advanced users, a more in-depth task manager can
be opened by clicking on ‘more details.’

24. Windows 8, Windows Defender (a standard
service in Windows 7) takes a step up from just
an anti-spyware package and becomes a full an
means that every Windows 8 machine ships
with Microsoft Security Essentials.
So, Windows 8 is more protected in comparison
to Windows 7.

25. • When Windows 8 gets corrupted, users now have two options:
refresh and reset.
• Refresh: Retains your customizations and re-installs window in-
place.
• Reset: Resets your installation to its initial state. It deletes all your
personal data and software.
• In Windows 7, the cpu restores all the default contents on
restarting.
12. System Recovery

26. Windows 7 (x64) introduce new operating system
support for User-Mode Scheduling. User-mode
scheduling (UMS) is a light-weight mechanism with
system API’s that applications can use to schedule
their own threads.. Windows 8 uses round robin
CPU scheduling algorithm.
Thus, windows 7 has a user mode scheduling in
comparison to round robin scheduling of windows
8.

27. 14. Memory Consumption
The comparison was made when memory was used
to install both operating systems on a 1GB RAM
machine (minimum OS RAM requirement) and their
comparison when they've been rebooted multiple
times, and then idled for a while. It was found that
windows 8 consumes less memory in comparison to
windows 7.

28. 15. Cloud Integration
Earlier, it was not possible to store large amount
of data on servers but cloud computing have
made it possible. Windows 7 is not representing
cloud based services but Windows 8 does.

29. 16. Supported File Systems
• Windows 7 supports NTFS, FAT16,
FAT32, HPFS, along with network file systems.
• Windows 8 introduced a new ReFS (Resilient
File System), which replaces the traditional
NTFS file system.
• Less prone to crash and errors.

30. 17. Network Differences
Windows 8 allows us the feature of managing
the amount of internet data used by the system
which is not available in case of windows 7.
Windows 8 does not allow to create ad-hoc
networks but still able to connect to such
networks while in case of Windows 7, we can
both create and connect to ad-hoc networks.

31. Why use Windows 8
1. The Start screen
2. Snap Apps
3. Picture Password
4. Reset and Refresh
5. Windows Store
6. Secure Boot, trusted Boot
7. Skype
8. ARM
9. Sky Drive
10. Multiple Monitor Options

32. Conclusion
Windows 8 is actually a significant upgrade to Windows 7.
Windows 8, through various low-level changes, could
improve the speed of productivity apps (Office, Photoshop,
etc.) significantly. We may have some concerns about the
clunky integration between the new (Metro) and old
(Desktop), but really, over time, these concerns should fade.
From time to time we will experience the brutal cross-
paradigm UI train wreck head-on some settings can only be
tweaked in the Metro-style Control Panel, for example but
these cases are fairly few and far between, once we’ve got
system fully set up. The fact that Microsoft isn’t making a
version of Windows 8 specifically for non-touch screen
devices, without Metro, is a bitter pill to swallow from an
ideological standpoint, and I suspect many consumers will
hold out for this reason.
