How to update OH2.1 to OH2.2 on windows if OH2.1 runs as a service?

[HomeAutomation]

I ask this because I had some problems with update form OH2.0 to OH2.1.

As written here:

openhab/openhab-distro

I should do:
start powershell as admin
cd C:\openHAB
. .\runtime\bin\update.ps1
Update-openHAB -OHVersion 2.2.0

Some questions:

• Should I stop OH 2.1 before?
• Is the windows service running again without any changes or must I do the steps from here again?
  http://docs.openhab.org/installation/windows.html#updating-the-openhab-runtime
• If I have to do this again, is the docu correct or are there changes for OH2.2?

Does it make sense to add the douc about starting as a service to the global OH2.2 docu. I think it is only available under the link above for update OH2.0 to 2.1 not for a fresh installation of OH2.2.

Should I stop OH 2.1 before?

Yes

Beyond that I don’t run on Windows so can’t answer the rest of the questions.
