In Microsoft's command-line interpreter [[Windows PowerShell]], <code>kill</code> is a predefined [[alias (command)|command alias]] for the <code>Stop-Process</code> [[cmdlet]].

[[Windows XP|Microsoft Windows XP]], [[Windows Vista|Vista]] and [[Windows 7|7]] include the command <code>taskkill</code><ref>{{cite web

[[GNU]] versions of <code>kill</code> have been ported via [[Cygwin]] and run inside of the Unix environment subsystem that [[Microsoft Windows Services for UNIX]] provides (Microsoft acquired Windows Services for Unix wholesale via their purchase of Softway Systems and their [[Interix]] product on September 17, 1999).<ref>{{cite web

The [[ReactOS]] implementation is based on the Windows variant. It was developed by Andrew Riedi, Andrew Nguyen, and He Yang. It is licensed under the [[LGPLv2.1]]  or later.<ref name="reactos">[https://github.com/reactos/reactos/blob/master/base/applications/cmdutils/taskkill/taskkill.c reactos/taskkill.c at master · reactos/reactos · GitHub]</ref> 

====Examples====
Find all processes beginning with the letter "p" that were developed by Microsoft and use more than 10 MB of memory and kill them:

<syntaxhighlight lang="ps1con">
PS C:\> ps p* | where { $_.Company -like "Microsoft*" -and $_.WorkingSet -gt 10MB } | kill -confirm

Confirm
Are you sure you want to perform this action?
Performing operation "Stop-Process" on Target "powershell (6832)".
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "Y"): A
PS C:\>
</syntaxhighlight>

Here is a simpler example, which asks the process [[Windows Explorer|Explorer.exe]] to terminate:
<syntaxhighlight lang="ps1con">PS C:\> taskkill /im explorer.exe</syntaxhighlight>
This example forces the process to terminate:
<syntaxhighlight lang="ps1con">PS C:\> taskkill /f /im explorer.exe</syntaxhighlight>
Processes can also be killed by their [[Process identifier|PID number]]:
<syntaxhighlight lang="ps1con">PS C:\> taskkill /pid 3476</syntaxhighlight>
