I have a process I'd like to kill:

```
$ ps Sourcetree

Handles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName
-------  ------    -----      -----     ------     --  -- -----------
   1311     116   136720     137804      57.45   1044   1 SourceTree

```

Send it to [`Stop-Process`, aka `kill`](https://technet.microsoft.com/en-us/library/ee177004.aspx):

```
$ ps Sourcetree | kill

```

Runs without error. But the process isn't killed:

```
$ ps Sourcetree

Handles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName
-------  ------    -----      -----     ------     --  -- -----------
   1311     116   136720     137804      57.45   1044   1 SourceTree

```

**How can I forcibly kill a process using powershell?**
