Minor Upgrading Jenkins using an MSI package while a previous version of Jenkins is running will open a dialog saying "... a reboot will be required to complete the setup." To reproduce, double-click jenkins-1.587.msi and complete the installation, then double-click jenkins-1.589.msi to upgrade.
I do not believe a reboot should actually be necessary. The dialog is not displayed if the user manually stops the service before running the newer MSI, but that workaround is not user-friendly. If the MSI installer would stop the service early on during the upgrade, I suspect the dialog would not be shown.
I'm not sure if the ServiceControl element defined in https://github.com/jenkinsci/jenkins/blob/master/msi/jenkins.wxs is supposed to stop the service during upgrades. I also don't know if this is a problem with the WiX definition or a winsw issue. Another app I know of also uses winsw and WiX and has the same issue.

We're probably going to disable upgrades using the installer. The preferred method is to use the internal upgrade utility to upgrade the WAR.

I discovered that if I make the MSI installation non-interactive by removing all UI elements from the .wxs file, the installation will not prompt for a reboot and will stop the previously running service as expected.
