Answer 1

After some research I was able to find a solution:

function prereq {
    if ((Get-Command aws -ErrorAction SilentlyContinue) -eq $null) {
        Write-Host "Unable to find aws.exe in your PATH."
    } else {
        $command = "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12"
        Invoke-Expression $command
        Invoke-WebRequest -Uri "https://awscli.amazonaws.com/AWSCLIV2.msi" -Outfile C:\AWSCLIV2.msi
        $arguments = "/i `"C:\AWSCLIV2.msi`" /quiet"
        Start-Process msiexec.exe -ArgumentList $arguments -Wait
    }
}

If you are using PowerShell 7, you can easily install it using the Windows Project Manager(WINGET). Use following command >

winget install --id "Amazon.AWSCLI"

You can also look for it and other AWS utilites using the following command >

winget search --name "aws"
