I have used:

$ComputerlistPath = 'c:\temp\computerlist.txt'
$ComputerList = Get-Content -Path $ComputerlistPath; # one computer a line
foreach ($computer in $computerList){
    ($computer + ": " + @(Get-WmiObject -ComputerName $computer -Namespace root\cimv2 -Class Win32_ComputerSystem)[0].UserName);
}

To get this information a few times. you can probably use this as a basis to make a script do what you want.

[Configuration manager 2012r2 - Site system proxy freezes]

When I try to set a proxy in Configuration manager 2012r2 on the Site system properties. The console freezes. I have to kill the console from task manager to continue using it. And the proxy does not get set

 

Anyone else having this problem? I can not find any logs that says anything.

[Script to remove all unknown printers from registry]

Removing all network printers is not that difficult with Powershell on the win7 machines. This one liner will remove all network printer connections:

 

Get-WMIObject Win32_Printer | where{$_.Network -eq ‘true’} | foreach{$_.delete()}

 

 

But this will only remove the connections If you want to remove the drivers also you need to use prnmgr.vbs see: http://technet.microsoft.com/en-us/library/cc725868(WS.10).aspx

 

The script i used earlier this year to achieve almost the exact same thing as you was this script.:

 

 

#Delete_printers.ps1

Write-Host ‘Tar bort alle Nettverksskrivere fra “Enheter og skrivere”‘ -ForegroundColor Green

Get-WMIObject Win32_Printer | where{$_.Network -eq ‘true’} | foreach{$_.delete()}

Write-Host ‘Restart Print Spooler’ -ForegroundColor Green
(get-wmiobject -Class win32_service -filter “Name=’Spooler’”).stopservice()
sleep 5
(get-wmiobject -Class win32_service -filter “Name=’Spooler’”).startservice()
sleep 10

Write-Host ‘Sletter Driverne’ -ForegroundColor Green
Invoke-Expression “cscript C:\Windows\system32\Printing_Admin_Scripts\en-US\prndrvr.vbs -x”

 

 

After this is run use GPOs or a login script to set the new printers.
