Powershell: Changing registry key value

After posting Pagefile size bigger than 4095MB on Windows Server 2003 I had the Idea to change this registry values with powershell.

1. First start powershell
2. You can get all PS Drives with the command

   Get-PSDrive

   

3. Now you see the drive HKLM which stands for HKEY_LOCAL_MACHINE
4. Open this Registry Key

   Set-Location 'HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management'

5. With this command you get all the key values

   Get-ItemProperty -path .

6. With the next command you can set the the key value

   Set-ItemProperty -path . -name "PagingFiles" -value "D:\pagefile1\pagefile.sys 4096 4096"

And now the simple way with multiple entries:

$values = @"
D:\pagefile1\pagefile.sys 4096 4096
D:\pagefile2\pagefile.sys 4096 4096
"@
$keys = "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management"
$name = "PagingFiles"
Set-ItemProperty -path $keys -name $name -value $values
