openfiles /query
If you are running a system and you want to know who has files open on your computer, this command will provide you a list of those users and the files that they have open.
Note: If you get an error saying The system global flag ‘maintain objects list’ needs to be enabled to see local opened files, you can fix this issue by typing openfiles /local on. You will have to reboot the system but it will resolve the issue. |
Recover Information From A Corrupt File
recover filename.ext
If you have a disk with damaged sectors, you can attempt to recover as much information as possible from the damaged file. Data that is not damaged can be retrieved but data in damaged sectors will be lost. |
rexec remotePC defrag C: /F
This command used the rexec command to force a defragment of the C: drive on the computer named remotePC. You can use whatever you want to for the command (I just used defrag C: /F as an example). This is very useful for remote maintenance.
Retrieve Detailed System Information |
tasklist
taskkill /im programname.exe /f
It’s always good to know what is running on your system. This is the command line version of the processes tab in Taks Manager.
Kill A Program

dir *.ext /s /b > files.txt
This command line will create a file called files.txt. When you open this file, there will be a complete list of all the files in that directory and all subdirectories with the .ext extension. You can then open up this text file in any text editor and work this the information.By changing the ext part, you can select different files. For example, if you wanted to list all of the PDF documents, you would type:
dir *.pdf /s /b > files.txt |
ipconfig /all
This will retrieve a pile of information about your network connection and IP information. From this command, you can get:
Host Name
Primary DNS Suffix
Node Type
IP Routing Enabled
WINS Proxy Enabled
DNS Suffix Search List
Connection-specific DNS Suffix
Network Adapter Description
Physical (MAC) Address
DHCP Enabled
IP Address
Subnet Mask

Monitor Port Activity
netstat -a 30
This will show you all of the TCP/IP ports that are being used on your system and what they are connecting to (or being connected from). It will continue to monitor these ports and refresh the information every 30 seconds. You can change the refresh rate by changing the number at the end of the command. |
Reboot a Remote Computer
shutdown -r -f -m \\remotePC –c
"System will be rebooted in 20 seconds |
Automatically Defragment C: Daily
schtasks /create /tn "Defrag C" /tr "defrag c: /f" /sc daily /st 23:00:00 /ru "System"
This will set your computer to automatically perform a complete defrag of the C: drive each day at 11:00:00 PM (23:00:00). It does this by creating a scheduled task called Defrag C. It will run this command under the computer’s system account.
