I haven't played with Monad shell for a while, the next thing I know there is a new scripting language called "Microsoft PowerShell". At first, I thought it's a brand new language, but actually they renamed Monad and made it PowerShell.
After installation, I tried to run one of my earlier Monad scripts. Just like the previous updates of Monad, the default execution policy is "Restricted". Under this policy, you can use PowerShell interactively. No scripts are allowed. If you like to run your own scripts without signing, you need to change the execution policy. Now there is a cmdlet to change policy without using regedit. Here is the cmdlet to change the policy to RemoteSigned.
