Computer step by step
 Make your Pc better
   The operating system's purpose is to interact with the user. One of his
functionality is to anticipate user's needs and use various methods to recover in
case of system failure. To achieve this, the operating system during his daily
functioning, collects and stores important data. He uses different methods for
different actions. For Browsing it saves all visited web pages. The purpose is, if you
want to access them again, they will load faster. If major changes take place, like a
driver installation, the system creates a system restore point. In case you experience issues
after this action, you have the option to restore to a previous time. The variety of today's programs can
create various problems and lets not forget about malicious software which were specially created to
destabilize your operating system. All these factors put together affect your overall computer performance.
   To gain back your system performance we recommend erasing certain files to free disk space, checking
system's files and partition to improve system's reliability, analyzing and reducing disk fragmentation to
optimize disk space.
   To increase the overall time of computer maintenance you can choose between the command line method
and normal method. We believe the method using command prompt is faster then the normal one, because
you can just select the whole command line, right click on the selected area,click Copy, then right click on your
command prompt window and choose Paste in order to copy it. However, we recommend to choose the one
you feel most comfortable with. Also for backup reasons we added for every method detailed articles with
pictures, you can access them by clicking on the operating system logo.

   Clean/Reset your browser

   A browser is a software application which helps you to load the websites you love so much. There are a
variety of browsers available for navigating the world wide web (www). Most popular ones are Internet
Explorer, Mozilla Firefox, Chrome, Opera, Netscape and Safari. In time your browser performance decreases
due to several reasons: add-ons, toolbars, plug-ins, etc.
   Toolbars, how did they arrive on your computer?
   Now a days almost each software comes with a toolbar which is mentioned during installation process and
it's added to your browser. One toolbar is not a lot, but in time by installing more applications you will find
your self with at least 5 or 6 toolbars.  A massive amount of toolbars will decrease your screen view and  
browsing performance.
    Each browser has a cache folder where it stores copies of accessed web content. The purpose of this
folder is to increase your network performance. When you access a web page which has been accessed
before it will be loaded it from cache. This technique has a downside, the cache content increases filling your
hard drive with unwanted files. This means less space for your system.
   Toolbars, add-ons and stored internet files lead to poor navigation experience. A quick resolution is to
reset your browser back to default settings. This procedure removes all customizations done to the browser:
removes your homepage settings, disables all add-ons and toolbars, erases your browsing history,deletes
all saved accounts and passwords and changes your security settings to default mode. Basically after this
step, you start with a fresh copy of your browser.
Note: Bookmarks or favorites will not be affected by this  procedure.
   Clean your temporary files following these steps:
   Internet Explorer
   Delete old windows update files

   Windows update is a Microsoft feature with the purpose to keep your system up to date by offering you
several patches, security updates, service packs and also new enhancements. This service scans your system
and provides you the possibility to choose which updates to install. There is no need to worry, all offered
updates are compatible with your system and all you need to do is to choose and start the installation
process. Once the process is started it will perform the required steps in the background and you can go on
using your computer without any interference. Some installed updates will require a system restart, if this is
the case you will be prompted to restart your computer or you can postpone it.
   During update process, windows updates are first downloaded and then saved on your computer. When
the process is completed these files remain on your computer reducing disk space. They can be deleted to
gain more free space.
    Delete your old windows update files following these steps:
   Using CMD
   In the Command Prompt window please select, copy and paste the following commands:

net stop wuauserv
ren %systemroot%\SoftwareDistribution SoftwareDistribution.old
net start wuauserv

   Check your system files integrity

   Also integrated in your operating system is the System File Checker Tool. It's a very useful and powerful
tool to restore corruptions in your windows system's files. Why do we need to use it? During every day use
we install several programs which need access to system files; they may need to modify them or even
overwrite them. This tool was created like a security measure to protect critical system files. Every change is
tracked by the system and a spare copy of the initial file is saved. Like this,your system protects him self from
malicious attacks, corruptions or several other problems.
    The tool is very easy to use, you just need to start the checking process. If any critical files are damaged
they will be restored automatically.
    Check your system files integrity following these steps:
   Using CMD
   In the Command Prompt window please select, copy and paste the following command:

sfc /scannow

Please press Enter to execute

Note: This command, depending of your operating system, will ask for windows installation cd
   Run a disk error checkup

   Your hard disk might have errors or corruption in the file or directory structure. They can be produced by
several causes: system freezes, inappropriate shut downs or power outages. The check disk command will
inspect your hard drive volumes and repair problems related to bad sectors, lost clusters, cross-linked files,
and directory errors. It will repair automatically any found errors. Mainly we recommend to run a check disk
for your system partition. Because the partition is in use, this check will be done next time when the
computer restarts. The process takes a while but it makes sure your disk is healthy.
    A regular disk checkup is part of a good system maintenance.
   Check your system files integrity following these steps:
   Using CMD
   In the Command Prompt window please select, copy and paste the following commands:

chkdsk /x /f /r
Y

After each command please press Enter
   Using Windows
   Please go to Start and open Computer

Right on your windows partition and choose Properties
In Properties window please go to Tools tab and press on Check Now... button
In Check Disk Local Disk window please check Automatically fix file system errors, Scan for and
attempt recovery of bad sectors boxes and click on Start button
Because this is your system partition you will be informed that this utility will run on the next restart.
Please confirm the pop-up.
   Defragment your disk drive volumes

   Another useful tool is Disk Defragmenter Utility. All files that are stored on your hard disk are physically
organized in contiguous or in smaller fragments. Accessing fragmented files is slower then accessing content
from a contiguous region. By defragmenting the disk, we reduce the time to read and write data. Another
advantage is that it will speed up your system startup time.
   A regular defragmention will maintain your disk performance.
   Check your system files integrity following these steps:
   Using CMD
   In the Command Prompt window please select, copy and paste the following command:

dfrgui.exe

Please press Enter to execute
Please select your system partition and click on Defragment now button
   Using Windows
   Please go to Start->All Programs->Accessories->System Tools and select Disk Defragmenter

Please select your system partition and click on Defragment now button
