Install-windowsupdate error when restarting

migrated from https://boxstarter.codeplex.com/workitem/57

When using the command Install-windowsupdate from BoxstarterShell everything works until the first restart. Errormessage as follows:

+ Boxstarter starting Downloading 1 updates
+ Boxstarter finished Downloading 1 updates 00:00:03.6635341

Boxstarter: Restart Required. Restarting now...

Need to support Install-Windows Update outside of a boxstarter run

[mwallner]

@pauby - imo there are two possible ways to resolve this..

*1: change the reboot-wrapper for the sched.tasks so it always loads the full boxstarter context before executing anything *2: modify Install-WindowsUpdate so it doesn't rely on any boxstarter functionality.

what'd you suggest we should go for?

[pauby]

I'm inclined to go with 1 primarily because it seems like something you'd want after a reboot anyway?

this might be fixed with Boxstarter v3, I'm moving it to take a look at again in milestone 3.0.1 anyway.
