Update Powershell through command line

Solution 1:

Run this command : iex "& { $(irm https://aka.ms/install-powershell.ps1) } -UseMSI"

And then run the MSI with your parameters.

After this you need to update the modules.

Solution 2:

Open Powershell as admin and type the following command:

iex "& { $(irm https://aka.ms/install-powershell.ps1) } -UseMSI"

If you want to update to the latest preview, add the -Preview argument at the end:

iex "& { $(irm https://aka.ms/install-powershell.ps1) } -UseMSI -Preview"

Here's a little trick using Chocolatey

#Install Chocolatey
#region
echo "Setting up Chocolatey software package manager"
New-PSDrive -Name HKCR -PSProvider Registry -Root HKEY_CLASSES_ROOT

Get-PackageProvider -Name chocolatey -Force

echo "Setting up Full Chocolatey Install"
Install-Package -Name Chocolatey -Force -ProviderName chocolatey
$chocopath = (Get-Package chocolatey | 
            ?{$_.Name -eq "chocolatey"} | 
                Select @{N="Source";E={((($a=($_.Source -split "\\"))[0..($a.length - 2)]) -join "\"),"Tools\chocolateyInstall" -join "\"}} | 
                    Select -ExpandProperty Source)
& $chocopath "upgrade all -y"
choco install chocolatey-core.extension --force

echo "Creating daily task to automatically upgrade Chocolatey packages"

    ScriptBlock = {choco upgrade all -y}
    Trigger = New-JobTrigger -Daily -at 2am
    ScheduledJobOption = New-ScheduledJobOption -RunElevated -MultipleInstancePolicy StopExisting -RequireNetwork

You should download WMF 5.0 from here. Then run a command from cmd:

wusa.exe D:\W2K12-KB3134759-x64.msu

or where you've downloaded package.
