In the day-to-day activities of a teacher of ICT, you definitely encounter a few challenges here and there. Viruses, slow internet, corrupted flash drives, unresponsive operating systems are just some of the challenges we face everyday.
Sometimes, the obvious solutions fail to rectify the problems. This then calls for one to try out DOS based solutions. In this article, I share with you just 5 DOS commands that could come in handy in the event that the obvious solution fails.
1. Ping: Use this command to find the quality of your internet.
Step 1: Open the Run dialogue box (Win key + R)
Step 2: Type cmd and click OK.
Step 3: In the DOS window type the following command and press enter. ping yahoo.com -t (Mind the spaces)
A steady stream like this shows a good internet connection
2. Format: use this to format a stubborn flash disk or hard drive.
Step 1: Identify the drive letter of your flash drive. In the figure below, its drive F:
Step 2: Open command prompt and type format f: then press enter.
At, this point, press the enter button and wait for it to progress to 100%.
Step 3: At the next screen, simply press enter
Your flash drive is now ready
3. ipconfig: use this command to know your computer’s IP address, that of your router and subnet mask.
Step 1: Connect your PC or laptop to a network. (In most cases, this is automatic)
Step 2: Open command prompt and type ipconfig then press enter
In the picture above,
4. slmgr -rearm: Use this to extend your windows license when it expires
Step 1: Open command prompt
Step 2: Type the following command and press Enter: slmgr -rearm
Step 3: Restart your computer
5. Attrib: Use this command t deal with stubborn viruses on your flash drive.
Step 1: Open command prompt
Step 2: Identify the drive letter
Step 2: Type the following command and press Enter: F: attrib This will display the file attributes including the file extensions on your flash drive. Identify the problematic file extensions which are usually, .lnk, .vbs, .exe, .wsf
Step 3: Type this command and press enter f: attrib -s -h -r /s /d *.*
Step 4: Type del *.lnk then press enter. (This removes shortcuts) Do this for other problematic file extensions like .bat, .wsf, .exe, .vbs . You can refer to this article on how to manually remove viruses.
