2. To enter in Windows Tools, you must
follow the next picture.

3. Is a computer maintenance
utility included in Microsoft
Windows designed to free
up disk space on a
computer's hard drive. The
utility first searches and
analyzes the hard drive for
files that are no longer of
any use, and then removes
the unnecessary files.

4.  Is used to view the
characters in any
installed font, to check
what keyboard input
(Alt code) is used to
enter those
characters, and to
copy characters to the
clipboard in lieu of
typing them.

5. Designed to increase access speed by
rearranging files stored on a disk to
occupy contiguous storage locations, a
technique called defragmentation.
Defragmenting a disk minimizes head
travel, which reduces the time it takes to
read files from and write files to the disk.

6. Provides users with the ability to
view the status of computer security
settings and services. This initial
version provides monitoring of
Windows Update, Windows
Firewall, and the availability of an
anti-virus software package

7. This tool can be used to collect
information about your
computer, from
others tools, diagnose
problems…

9.  Seven computers.
 Switch o hub: The switch is where you will plug in your
IP cameras, NVR, IP storage array, video servers, etc and
the switch will quickly connect all of them together and
enable communication.
 Ethernet cable: Systems communicating over Ethernet
divide a stream of data into shorter pieces called frames.
Each frame contains source and destination addresses
and error-checking data so that damaged data can be
detected and re-transmitted.

10.  Rj45: a connector for computer network
 (Ethernet) cables.
 Network printer
 Network card: is a computer hardware component that connects a
computer to a computer network.
 USB cable: was designed to standardize the connection of computer
peripherals to personal computers, both to communicate and to supply
electric power
 Printer
 Router : is a device that forwards data packets between computer
networks, creating an overlay internetwork. A router is connected to two or
more data lines from different networks.
 Telephone cable
 Telephone socket

12.  To use the protocols you must follow next
pictures.
• Click on “start” and then, control panel.
• Please double-click the Network
Connections icon.
• Select the icon Local Area Connection 2
and with the right button of the mouse you
select Properties.
Pressing the Setup button on the window
that appears
shown below where you can access some
Features of this adapter.

13.  From the Properties window of the
Local Area Connection that
shown above on the left, select the
Internet Protocol item
(TCP / IP) and clicking on the
Properties button, the window
Properties Internet Protocol (TCP /
IP) (top right),
where are some data relating to the
operation of these
protocols.

15.  is a native Windows application usually
running in Win32 console. This allows it to
take advantage of features available to
native programs on the platform that are
otherwise unavailable to DOS programs.

16.  If you are having connectivity problems, you can use the ping
command to check the destination IP address you want to reach and
record the results. The ping command displays whether the
destination responded and how long it took to receive a reply. If there
is an error in the delivery to the destination, the ping command
displays an error message.
You can use the ping command to:
• Ping your computer (by address, not host name) to determine that
TCP/IP is functioning. (Pinging your computer does not verify that
your network adapter is functioning.)
• Ping the local router to determine whether the router is running.
• Ping beyond your local router.

17. My computer

computer
(invented)

19.  You can use the ifconfig command to assign an address to a network
interface and to configure or display the current network interface
configuration information. The ifconfig command must be used at
system startup to define the network address of each interface present
on a machine. After system startup, it can also be used to redefine an
interfaces address and its other operating parameters. The network
interface configuration is held on the running system and must be
reset at each system restart. The ifconfig command interprets the
IFF_MULTICAST flag and prints its value if it is set.

21. There are some computer problems, now
I´m going to explain one solution for this
two. These problems can cause that our
computer goes slow, have a lot of virus…

22. “SOME FILES COULD NOT BE SCANNED”
It means that the scanner was
blocked, somehow, from scanning those
files. I suggest you run another scan, this
time in Safe Mode With Networking. That
sometimes keeps malware from protecting
itself. In other words, your anti-malware may
be able to scan and fix those files.
To get into Safe Mode with Networking:
1. Log out and reboot your machine.
2. When the machine starts the reboot
sequence, press the F8 key repeatedly.
3. Select Safe Mode with Networking from
the resulting menu.
4. Login. If the malware has changed your
password, try logging in as Administrator. By
default, Administrator has no password.
5. The machine will continue booting, but
the Windows desktop will look different.
6. When you're finished doing what you
need to do, log out and reboot back into
normal mode.

23. “ WINDOWS GENUINE ADVANTAGE”
The easiest way to do this is...
Search online for the "Windows 7 Loader"
program. It is completely automated and will
automatically give your computer a valid
activation key. I think that the version that I used
(as a test, of course) is version 1.7.7.
However,
Following three simple steps now you can get rid
of the pesky and sometimes buggy Windows
Genuine Advantage (WGA) notifications:
1. Reboot Windows in safe mode (hold the f8 key
while booting and you will get the option to boot
in safe mode) and then:
2. Open Registry Editor (regedit.exe) and search
for wgalogon folder and delete it. You should
backup up the registry before hand, in case
something goes wrong.
3. In your windows directory search for files wga*
and delete them. when you search for wga*
please don't delete wgapi.dll if you found. This
dynamic link is not related with that notifications
massage.
You are done!
Now reboot back normally and continue your
work. Windows Genuine Advantage will not
bother you anymore.
Note: Now it is not required anymore. You can do
it yourself by carefully following the guide above.
