Powershell script to change Pagefile (Virtual memory) size on remote computers using PDQ deploy.
Looking for a Powershell script to deploy to remote labs using PDQ Deploy that will change/set the size of the Pagefile (Virtual Memory). I have found a couple older posts online that offer some options but I can't get them to work with PDQ deploy. Any direction and assistance is appreciated.

Can you post what you are using? And any error information? I suspect you would want to use WMI to accomplish this.
Here is the script from the PS that I dowloaded:
#Requires -Version 3.0
Function Set-PageFile {
<#
.SYNOPSIS
Set-PageFile is an advanced function which can be used to adjust virtual memory page file size.
.DESCRIPTION
Set-PageFile is an advanced function which can be used to adjust virtual memory page file size.
.PARAMETER <InitialSize>
Setting the paging file's initial size.
.PARAMETER <MaximumSize>
Setting the paging file's maximum size.
.PARAMETER <DriveLetter>
Specifies the drive letter you want to configure.
.PARAMETER <SystemManagedSize>
Allow Windows to manage page files on this computer.
.PARAMETER <None>
Disable page files setting.
.PARAMETER <Reboot>
Reboot the computer so that configuration changes take effect.
.PARAMETER <AutoConfigure>
Automatically configure the initial size and maximumsize.
.EXAMPLE
C:\PS> Set-PageFile -InitialSize 1024 -MaximumSize 2048 -DriveLetter "C:","D:"
Execution Results: Set page file size on "C:" successful.
Execution Results: Set page file size on "D:" successful.
Name InitialSize(MB) MaximumSize(MB)
---- --------------- ---------------
C:\pagefile.sys 1024 2048
D:\pagefile.sys 1024 2048
E:\pagefile.sys 2048 2048

This is how the site said to execute:
.\set-pagefile.ps1 -InitialSize 65536 -MaximumSize 65536 -DriveLetter "C:"
Error I get from PDQ deploy:
The term '.\set-pagefile.ps1 -InitialSize 65536 -MaximumSize 65536 -DriveLetter "C:"' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was
included, verify that the path is correct and try again.
I think I know what's wrong here. can you post a screenshot of your step settings?
Yup, there's a a quotation issue. I can't quite see the full command but you are basically saying
You'll want to change it to:
Them quotes can be pretty fickle at times!
AWESOME!! Thank you. It worked.
Glad to hear it! Happy Powershelling!
Ok, I was wrong. It doesn't error but it also doesn't change the settings. It is still set to Automatic manage. I need it to disable the automatic management and enable custom management with a min and max set to 65536 (3x physical memory).
I am doing this because it is suggested by Adobe as a possible solution to the computers slowing down or freezing when running Adobe Illustrator and Photoshop. I figured the best way would be a PS and push the settings to the labs.
What OS(s) are you deploying this too?
Just use this, it is way easier. Note, this is not my code entirely, I just found it online,dressed it up a little bit, and tested it on my Windows 10 workstation. Does what it is supposed to as far as I can tell.
Here's where I found it if you are interested: https://social.technet.microsoft.com/Forums/ie/en-US/557b0eea-c981-48fe-b830-8f9de0587c84/inconsistent-win32pagefilesetting?forum=winserverpowershell
And some reading on the class itself so I could better understand what all it was doing: https://msdn.microsoft.com/en-us/library/aa394245(v=vs.85).aspx
This is deployed to Windows 10 - 1703. Thank you for the new code.
Tested - but when I go to the computer to check it is still managed by windows and the min and max aren't set.
Well huh, that's rather interesting. I'll do some more testing on my end and see if I can replicate those results with a package. I'm wondering if the RunAs options are causing an issue.
I won't be able to circle back to this until tomorrow, but I'll see what I can come up with.
