I wrote a Powershell script. I’ll submit a PR to get it included in the installer. You can download and take a look if you would like.
It also updates the area in the registry that the Apps area in System settings gets its data from as well so that when you look there it will show the version of the war.
It’s currently AuthenticodeSigned with my own self generated key, so if you wanted to run it, you would want to remove that. It will be signed with the Jenkins project key in the installer.
