Restart PSU through the UI

PowerShell Universal
1

Would it be a good idea to have something like “restart Service” in the UI somewhere? Maybe under the platform somewhere?

We run ours as a service and I tend to reboot PSU to test certain functionality and I always have to fire up services.msc.

I think that would be handy. In the interim, I’d think you could use the PowerShell cmdlets Restart-Computer or Restart-Service in a script inside of PSU, lock it down via roles or such to only certain people, and just use PSU’s “run” button to trigger it.

The obvious caveat would be, if PSU is not responding to be able to do that you’d still have to rely on other methods.

Why don’t you create an app that offers that functionality?

I don’t use apps tbh.

I’ve already got a dashboard for doing just this. It might need a little tweaking for a different environment, but the bones should be there.
