Sometimes when upgrading the web installation we must restart the web server and sometimes not.
Is there any recommended ways to avoid such a restart (If possible)? Should we stop all SO Web sites and App pools before installing or let them run.
Any other processes or services that should be stopped? Or is this just a bit random depending on Win update status or other programs installed on the same server?
It feels like it more often now when upgrading to 8.2 then before.
