Cumulative Update KB4482887 Windows 10 v1809 Build 17763.348 - March 1 Win Update

To install the latest version of the SpeculationControl script, open PowerShell as Admininstrator and run the command

Code:

Find-Module -Name 'SpeculationControl' | Save-Module -Path "$env:ProgramFiles\WindowsPowerShell\Modules" -Force

Prerequisite: Internet connection.

If you're on PowerShell version 4 and above, once you save the module in the $env:ProgramFiles\WindowsPowerShell\Modules path, there is no need to install the module, since the $env:ProgramFiles\WindowsPowerShell\Modules folder is included in the $env:PSModulePath system variable and PowerShell will find it, without any installation.

And one last thing.
To run the Find-Module command you need to have installed the NuGet provider.
If you don't have it, once you run the above command, you will be asked to install Nuget. Go ahead and install it.

After that how can uninstall the old one. I know with -force both versions exist side by side.

The easiest and fastest way is to uninstall all previous versions and install the latest one (something like clean-install).
Do this by running the following command in an elevated PowerShell

Code:

Uninstall-Module -Name 'SpeculationControl' -Force -AllVersions
Find-Module -Name "SpeculationControl" | Save-Module -Path "$env:ProgramFiles\WindowsPowerShell\Modules" -Force

If you do want to just delete all previous versions, try the following in an elevated PowerShell

Code:

$InstalledVersions = Get-InstalledModule -Name 'SpeculationControl'
foreach ($v in $InstalledVersions) { 
    Get-InstalledModule $v.Name -AllVersions | Where-Object {$_.Version -ne $v.Version} | Uninstall-Module -Verbose
    }

Guys, what's the default Execution Policy for the 5 Scope?

If I remember correctly the defaults for all is "Undefined", except for LocalMachine, which is "Restricted".
Exactly what you have in your image.

You're welcome! (Παρακαλώ)
