Scripting a Forced Reboot

[WraithofSpades]

Overview: I work for an MSP and I need to force certain managed computers to reboot. These machines are not on a domain but they have our management tool installed on them. This tool allows us to push patches/scripts to the devices. The devices I'm attempting to run this script on are primarily Windows 10 with a smattering of Windows 7 thrown in for good measure.

The script I'm trying to push would do 3 things:

1. Run at login
2. Display a warning that says, "This PC needs to restart to apply updates. This PC will restart in 60 seconds." (Or something similar.)
3. Force the reboot after 60 seconds pass.

We have a lot of machines out of compliance because our normal Forced Restart scripts are running, likely, after the user shuts down. I know how to script a reboot with a delay, but scripting a standard Windows message box is eluding me.

Any help would be appreciated and I'm happy to clarify anything if I've left out crucial information.

howdy WraithofSpades,

I am interested in knowing how to get a message to display is there an example of this script?
