You may already be familiar with chkdsk. After an unexpected shutdown, Windows will sometimes halt a reboot to run chkdsk, in order to check for bad sectors and repair errors on the disk. As a a slightly faster alternative, you can also open a PowerShell window as an administrator (Win+X or right-clicking on the Start button). It’ll work the same as the Command Prompt. Right-click on the result for the Command Prompt, then choose Run as administrator. To open a Command prompt as an administrator, hit the Windows key or click on Start button, then type cmd. Running sfc /scannow will check for corrupted files on your system and attempt to repair any files with problems. When parts of the Windows interface start acting up-say, disappearing taskbar icons-it may be time to lean on the System File Checker. It’s more rare that we want only the information that ping reveals, hence tracert’s place on this list. Ping is better for answering the question “Is there a connection and how fast is it?”, while tracert answers both that and “Where does the connection fail?”. This tells the command prompt to run what we type after it, then stay open so that you can see the result. You may notice the odd '/k' in the middle of the command. By default, the report will save to your Windows 10 user folder under the name “battery-report.html” For example, the following command will tell the command prompt to print 'hello world:' 'C:WindowsSystem32cmd.exe' /k echo hello world. If you’ve felt like your battery life has taken a sudden dip, this information will share the battery level at certain points in time, along with the time it recently took to drain since last plugged in. The powercfg command can be of use to both desktop PC and laptop owners, especially if you need to toggle the hibernation feature ( powercfg /hibernate) or begin an investigation into what’s disturbing your computer from sleep ( powercfg /lastwake).īut laptops benefit the most from the gem among powercfg’s operations: the battery report ( powercfg /batteryreport). If you never use Run for anything else, it’ll remember this command whenever you next call it up, making it slightly faster than opening a fresh Command Prompt window each time. You can also turn off history while you’re in that menu.)Īn alternative way to use this command is to open Windows 10’s Run command window (Win + R) and enter cmd /c “echo off | clip”.

(This command won’t clear your full Clipboard history though, so you’ll have to use Windows 10’s Clipboard settings to do that. You can execute Windows Command prompt commands using a C++ function called system(). Entering this string into the Command Prompt clears the last item on your Clipboard-helpful when you’ve copied sensitive information and are done with it.
