Most files in Windows are associated with a specific program that is assigned to open the file by default. Sometimes it can be confusing to remember these associations. You can remind yourself by entering the assoc command to display a complete list of file name extensions and program associations.
You can also expand the command to change file associations. For example, assoc .txt= will change the association for text files to whatever program you type after the equals sign. The Assoc command itself will reveal both the extension name and the program name, which will help you use the command correctly.
In Windows 10, you can see a more user-friendly interface, which also allows you to change file type associations on the fly. Go to Settings (Windows + I) > Apps > Default apps > Choose default app by file type .
Removing files on a mechanical hard drive doesn't actually delete them. Instead, it marks the files as inaccessible and the space they take up becomes unused. The files remain recoverable until the system overwrites them with new data, which can take some time.
However, the cipher command will delete a directory by writing random data to it. For example, to delete drive C, you would use the cipher /w:d command , which will wipe the free space on the drive. The command does not overwrite undelete data, so you will not wipe out the files you need by running this command.
You can use a variety of other cipher commands, however, they are often redundant with versions of Windows that support BitLocker .
Drivers are still some of the most important pieces of software installed on your PC. Missing or incorrectly configured drivers can cause all sorts of problems, so it’s good to have access to a list of the drivers on your PC. That’s exactly what the driverquery command does. You can expand it to driverquery -v to get more information, including the directory in which the driver is installed.
You can use this command to determine the text differences between two files. It is especially useful for writers and programmers trying to find small changes between two versions of a file. Just type fc , followed by the directory path and names of the two files you want to compare.
You can also extend the command in a number of ways. Typing /b compares only binary output, /c ignores uppercase and lowercase in comparisons, and /l compares only ASCII text.
So, for example, you could use the command like this:
fc /l "C:\Program Files (x86)\example1.doc" "C:\Program Files (x86)\example2.doc"The above command compares the ASCII text in two Word files.
This is a more advanced version of ping that is useful if there are multiple routers between your PC and the device you are testing. Like ping, you use this command by typing pathping followed by the IP address, but unlike ping, pathping also relays some information about the path the test packets take.
Powercfg is a very powerful command for managing and monitoring how your computer uses power. You can use the powercfg hibernate on and powercfg hibernate off commands to manage hibernation; or you can also use the powercfg /a command to see the current power saving states on your PC.
Another useful command is powercfg /devicequery s1_supported , which displays a list of devices on your computer that support connected standby. When enabled, you can use these devices to wake your computer from standby, even remotely. You can enable this feature by selecting the device in Device Manager , opening the device's properties, going to the Power Management tab , and then checking the Allow this device to wake the computer box .
Powercfg /lastwake will tell you which device last woke your PC from sleep. You can use this command to troubleshoot your PC if it seems to be randomly waking up from sleep.
You can use the powercfg /energy command to generate a detailed power consumption report for your PC. The report is saved to the specified folder after the command finishes. This report will tell you about any system errors that may be causing increased power consumption, such as devices that block certain sleep modes or are poorly configured to meet your power management settings.
Windows 8 added powercfg /batteryreport , which provides detailed analysis of battery usage, if available. Typically exported to your Windows user folder, the report provides details on the duration and length of charge and discharge cycles, average battery life, and estimated battery capacity.
This command will give you an overview of your computer's detailed configuration. The list includes your operating system and hardware. For example, you can look up the original Windows installation date, last boot time, BIOS version, total and available memory, installed hotfixes, network card configuration, and more.
Use systeminfo /s followed by the host name of a computer on the local network, to get remote information for that system.
This may require additional syntax elements for domain, username, and password, as follows:
systeminfo /s [host_name] /u [domain]\[user_name] /p [user_password]
System File Checker is an automatic scanning and repair tool that focuses on Windows system files.
You'll need to run Command Prompt with admin rights and enter the command sfc /scannow . If SFC finds any corrupt or missing files, it will automatically replace them using cached copies kept by Windows specifically for this purpose. The command may take half an hour to run on older laptops.
You can use the tasklist command to get a current list of all the tasks running on your PC. While somewhat redundant given the existence of Task Manager , this command can sometimes find tasks that are hidden from view in that utility.
There are also a variety of modifiers. Tasklist -svc shows the services associated with each task, use tasklist -v for more details on each task, and tasklist -m will locate the DLL files associated with the active tasks. These commands are useful for advanced troubleshooting.
Windows automatically flags a drive for a diagnostic chkdsk scan when symptoms indicate that the local drive has bad sectors , lost clusters, or other logical or physical errors.
If you suspect your hard drive is failing, you can start a scan manually. The most basic command is chkdsk c: , which will immediately scan the C: drive without restarting your computer. If you add parameters like /f, /r, /x, or /b , as in chkdsk /f /r /x /bc: , chkdsk will also repair errors, recover data, unmount the drive, or clear the bad sector list, respectively. These tasks require a reboot, as they can only run when Windows is powered off.
Schtasks is Command Prompt access to Task Scheduler, one of the many underrated Windows admin tools. While you can use the GUI to manage your scheduled tasks, Command Prompt lets you copy and paste complex commands to set up multiple similar tasks without having to click through multiple options.
For example, you can schedule your computer to restart at 11pm every Friday:
schtasks /create /sc weekly /d FRI /tn "auto reboot computer weekly" /st 23:00 /tr "shutdown -r -f -t 10"To supplement weekly restarts, you can schedule tasks to launch specific programs at startup:
schtasks /create /sc onstart /tn "launch Chrome on startup" /tr "C:\Program Files (x86)\Google\Chrome\Application\Chrome.exe"To replicate the above command for different programs, just copy, paste and modify it as needed.
If you want to map a new drive, you can always open File Explorer , right-click This PC , and go through the steps in the Map Network Drive wizard . However, using the Net Use command, you can do the same thing with a series of commands.
For example, if you have a shared folder on a computer on your network named \\OTHER-COMPUTER\SHARE\ , you can map it to your own Z: drive by typing the command:
net use Z: “\\OTHER-COMPUTER\SHARE” /persistent:yesA persistent switch tells your computer that you want this drive to be remapped every time you log back into your computer.
When you need to format a drive, you can use the Windows File Explorer GUI or switch to Command Prompt. You will need admin rights to use this command. Make sure you specify the volume you want to format, followed by the desired parameters.
The command below will quickly format drive D with exFAT file system, with size of 2048 bytes and rename the volume to "label" (without quotes).
format D: /Q /FS:exFAT /A:2048 /V:labelYou can also use this command to unmount the volume (/X) or, if it is formatted with NTFS, set the file compression mode to the default setting (/R). If you get stuck, use format /? to search for help.
If you find yourself cluttering up your Command Prompt window trying all of the commands above, there's one final command you need to know to clean it all up again.
