Using the Get-Process Cmdlet

Retrieving Process Information

The Get-Process cmdlet provides a quick and easy way to retrieve information about the processes running on your computer. To get a quick overview of all the processes currently running on your machine simply call Get-Process without any parameters:

Get-Process

By default, you’ll get back data similar to this:

Believe it or not, that’s all it takes. Only interested in the instances of Microsoft Word that are running on your computer? Then call Get-Process followed by the executable file name (without the file extension). In other words:

Get-Process winword

That results in output similar to this:

Handles  NPM(K)    PM(K)      WS(K) VM(M)   CPU(s)     Id ProcessName
-------  ------    -----      ----- -----   ------     -- -----------
    565      25    48760      77744   537   241.34   3116 WINWORD

Want to get back more than one process? Then just specify more than one executable name, separating the names with commas:

Get-Process winword,explorer

This time around your output will return information about both Word and Windows Explorer:

Handles  NPM(K)    PM(K)      WS(K) VM(M)   CPU(s)     Id ProcessName
-------  ------    -----      ----- -----   ------     -- -----------
    497      16    18524      28264    96     8.30   1080 explorer
    565      25    48760      77744   537   241.34   3116 WINWORD

Alternatively, you can use a wildcards to retrieve information about, say, all the running processes whose executable file name starts with the letter w:

Get-Process w*

With this command you get back pretty much what you’d expect to get back:

Handles  NPM(K)    PM(K)      WS(K) VM(M)   CPU(s)     Id ProcessName
-------  ------    -----      ----- -----   ------     -- -----------
     65       2     1628       1836    15     0.03   2024 wdfmgr
    557      65     8184       3824    57     1.06   1220 winlogon
    569      26    48748      77912   542   282.86   3116 WINWORD
    149       4     2024       5288    37     0.17    808 wmiprvse
     48       2      916       3404    29     0.06   2820 WZQKPICK

Although the functionality of the Get-Process cmdlet overlaps with the functionality of the WMI class Win32_Process, Get-Process can retrieve additional information not exposed through WMI, including properties such as company, file version, and product version. For example, this command pipes Get-Process through the Select-Object cmdlet, filtering out everything except the process name and the properties just mentioned:

Get-Process | Select-Object name,fileversion,productversion,company

Here’s the kind of information you can expect to get back:

Name                FileVersion         ProductVersion      Company
----                -----------         --------------      -------
alg                 5.1.2600.2180 (x... 5.1.2600.2180       Microsoft Corpor...

Note. Because of the length of some of these property values, you might want to pipe the output through the Format-List cmdlet.

So how do you know which process properties are available through Get-Process? Probably the easiest way to determine that is to simply call Get-Process and then pipe the returned information through the Get-Member cmdlet:

Get-Process | Get-Member

That will return a list of all of the cmdlet’s properties and methods.
