Some Notes on the Machines

An in-script fix:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

A permanent fix:

Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord
Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord

To download a single file in binary mode, try translating this:

Invoke-WebRequest -Uri "http://fq.dn/sub/binary.exe" -Outfile "C:\folder\binary.exe"

Prefix this, add a space to the end, and then type your Powershell:

%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command

My current favorite way:

[string]$PSVersionTable.PSVersion.Major + '.' + [string]$PSVersionTable.PSVersion.Minor

If it’s 1.0, you’ll get an error, otherwise you will have what you need.

Here’s a rundown:

If you place a tilde (~) before the command you enter, no space after, your command will be run within Powershell. For instance:

~dir
