Formatting of a Windows Computer

--Originally published at TC2027 – Titel der Website

Thats a blog post for two courses of Ken. TC1017 & TC 2027.

The reason why i took this topic is first of all, that Ken talked a lot in this semester about reason why we should Format a computer. Reasons are, that a student clicks a lot of times not serious links or just download a lot of trash to the computer. The result is most of the time a super slow computer. A computer which worked 1000 times slower than the first day of using.


An other reason is a personal reason. I guess i am one of the students, which did a lot of mistakes with clicking links and download trash. So why i post this is, i just Format one time in my life a computer by my own. I just want to do that again. To learn how it works and to rescue my lovely Surface 4 ?


To the operative work:

It is super easy to format a Windows computer nowadays.

The first step is to safe all your Datas, which you not want to lose. But important is, to realize that maybe movies, music or other stuff from strange websites could be the reason why a computer is not running like it should. So think twice if you also want to safe all the trash!

The reason for the first step is, that the computer will be empty after the process for Formatting.

Now the steps

  1. Simultaneously press the [Windows] and [R] keys to open the Run command.
  2. Enter „diskmgmt.msc“ here and confirm with „OK“. Subsequently, the disk management opens.
  3. Select the desired hard disk from the list and click on it with the right mouse button.
  4. Select the option „Format“ and confirm the process via the „OK“ button.
  5. Then the hard

Operating System Security (OS Security)

What is a Operating System Security?

The Definition of a OS is the process of ensuring OS integrity, confidentiality and availability. It uses special provisions to protect the system against threats, viruses, worms malware etc.

OS security encompasses all preventive-control techniques, which safeguard any computer assets capable of being stolen, edited or deleted if OS security is compromised.

Techopedia explains Operating System Security (OS Security)

OS security encompasses many different techniques and methods which ensure safety from threats and attacks. OS security allows different applications and programs to perform required tasks and stop unauthorized interference.

OS security may be approached in many ways, including adherence to the following:

  • Performing regular OS patch updates
  • Installing updated antivirus engines and software
  • Scrutinizing all incoming and outgoing network traffic through a firewall
  • Creating secure accounts with required privileges only (i.e., user management)


Network & Wireless Security

What is Network Security?

Network security is not a single established term, but includes all measures for planning, execution and monitoring of security in networks. These measures are by no means only of a technical nature, but also relate to the organization the operation (how can I apply network security in practice, without interrupting the operation at the same time?) and finally the law (which measures may be used?).


Wireless Security

The right wireless encryption for your router

WLAN name – SSID: This abbreviation stands for „Service Set Identifier“ and means the name of your WLAN. By default, this is usually the name of the DSL wireless router, such as Fritzbox 7270th These and all the following settings can be seen in the configuration interface of the router, which you can reach through your browser. The matching address is in the manual. Often it is something like this:,, or speedport.ip.

A recommendation is to assign a new, neutral name for the SSID. But don´t use the option to hide the name. It may happen, that hardware like Computer and Tablets cant connect with your WLAN

Encryption Standards – WEP, WPA, WPA2: The oldest standard has the abbreviation WEP (Wired Equivalent Privacy). Due to systemic vulnerabilities, the process is considered uncertain. The key to this encryption can be cracked in minutes. If your router or WLAN card in the PC only offers this standard, you should think about buying a new one. WPA (Wi-Fi Protected Access) is an evolution of the older WEP standard, but provides additional protection. But he has not yet built the better encryption with AES (Advanced Encryption Standard). This is only possible with the current standard WPA2.

WPA2 is
