Hi @osmayqc thanks for opening an issue. It looks like this might be an issue caused by a system configuration like group policy or execution policy.

Can you please try trusting the Microsoft signing certificate on the startup script by following these steps.

Some other things that might be responsible:

• A group policy configuration
• Antivirus
• Another form of system lockdown or restriction

I'm getting the same issue very often. I tried what you suggested, but it hasn't changed the behavior and I was never prompted.

[rjmholt]

@joshfria When you say "often" do you mean not always? Can you please follow the troubleshooting doc and report back here with as much information about your system as you can, including any configuration, policy or software that might be locking down your system?
