You are a Level 1 IT Support Technician. A user just submitted a panicked helpdesk ticket: 'My computer is running slow, the internet is acting weird, and my files are a mess. Please help!' You need to check out their system, run diagnostics, and clean up their workspace.
Go to this comand line online demonstrator: https://learnmandu.com/
Part One: As an IT tech, you never start fixing things without knowing exactly what machine you are working on. First gather the critical data for their "support ticket."
Commands: hostname, ver, systeminfo, time, getmac
First, document the exact time you started the ticket by typing time.
You will need need the computer's name (hostname) and the exact Windows build (ver).
Pull the physical hardware address of the network card using getmac.
Finally, they run systeminfo to gather the full profile of the machine.
Part Two: The user complained that their files were a mess. The technician (you) need to isolate a "suspicious" file, back it up, and remove the original.
Commands: md, echo, type, copy, ren, del, rd
Execute this exact sequence to simulate quarantine protocols:
Make a quarantine folder: md Quarantine
Create the user's messy file: echo test > messyfile.txt
Verify what is inside it: type messyfile.txt
Back it up to the safe zone: copy messyfile.txt Quarantine\backup.txt
Rename the original so it can't execute: ren messyfile.txt deadfile.txt
Delete the renamed file: del deadfile.txt
Clean up the quarantine area by deleting the backup: del Quarantine\backup.txt
Remove the now-empty directory: rd Quarantine
Part Three: The computermight be broken, so you need to use the "heavy artillery" to repair corrupted Windows files and fix physically bad sectors on the hard drive.
Run sfc /scannow (System File Checker) to verify the integrity of the OS.
Run chkdsk /f to locate bad sectors and recover readable information.
Part Four: The user also comlained about a slow PC and weird Internet.
Commands: ping, tasklist
Check the "weird internet" complaint, by running a network diagnostic by typing ping 8.8.8.8 (Google's DNS server) to ensure packets are successfully sending and receiving without loss.
To check the "slow PC" complaint, type tasklist.

If you need help with the commands, click the Commands button at the top right. Also, I want to emphasize that the command line is unforgiving with spelling and spaces. If you get an error, remind yourself to check your command syntax before getting frustrated.
