Update Powershell through command line

The mode command does not (directly) alter the size of the window, it alters the size of the buffer. If you set the numbers to something larger than the window size and it will create scrollbars as necessary. Setting it to numbers smaller than the window will remove the scrollbars and the window will shrink.

There is a StackOverflow question that gives some more solutions for finer-grained control via the registry or programming if you are interested.

This is just my thoughts and opinion on how I might do this...and I did change around the variables names a bit so they match up to the cmdlets used. You don't have to just made it more readable to me.

# I don't have a domain computer to work with so my local 
#  PC includes the "public" folder you likely want have 
#  this but nice to include just in case. As well the "Default*" 
#  is there because I'm on Windows 8.1 
#  so the upgrade modified the "Default" folder 
#  to be "Default.migrated" for some reason.

# The "-Exclude" allows you to put in the names of those items (directory names
#   or file names) that you want to exclude, it allows wildcard values as well)
#   Then as suggested in a comment using -ExpandProperty FullName allows the 
#   object to be passed as a string instead of a system object which
#   adds on extra characters that some other cmdlet may not like.
$userFolder = Get-ChildItem -Path 'C:\Users' -Exclude 'Default*','All Users','Administrator', 'Public' | 
   Select -ExpandProperty FullName

# just the file I was playing with here
$sFile = '.\text.txt'


foreach ($uf in $userFolder) {

    $dest = "$uf\AppData\LocalLow\Sun\Java\Deployment\"

# I want to test for the path to exist first and if it 
#  does then add the file, if it does not then you 
#  would create the directory and copy the file. 
#  I noticed in yours that you created an empty 
#  file and then copied it. Works the same way.

    if (Test-Path $dest) {
        Copy-Item -Path $sFile -Destination $dest -Force
    }
    else {
        New-Item -ItemType Directory -Path $dest -Force
        Copy-Item -Path $sFile -Destination $dest -Force
    }
}

As already noted I am on a standalone computer playing with this but the output of the commands I get are here:

New-Item -ItemType Directory -Path C:\Users\Shawn\AppData\LocalLow\Sun\Java\Deployment\ -Force
Copy-Item -Path .\text.txt -Destination C:\Users\Shawn\AppData\LocalLow\Sun\Java\Deployment\ -Force

You can also have it output the command it would execute if you want to test it first by just wrapping the commands in double-quotes: "Copy-Item -Path $sFile -Destination $dest -Force"
