Stopping Skype for Business Autostarting in Windows 10

Should be simple, right?

I installed Skype for Business for Office 365 on my home PC. I had Office 365 ProPlus, and the version of Skype for Business has to match that.

Worked great, and realising I didn’t want it running all the time on my home PC, I changed the option to ‘Automatically start the app when I log on to Windows’ in the Personal options:

The next day over the weekend, I noticed that Skype for Business had decided to still launch at login. Weird, so I checked what Task Manager had to say:

Skype for Business wasn’t even listed. I started mucking around a bit more, ticking the option to automatically start, pressing OK, turning it off, pressing OK, rebooting – but every time, Skype for Business just turned up, like a strange uncle you never invite to dinner but somehow still finds out and turns up every night.

Maybe it’s in the Startup folder in the Start Menu? Is that still a thing in Windows 10? Yes it is. It’s under C:\Users\username\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup – replacing ‘username’ with what you’re thinking you should replace it with. Except, there was nothing there.

I also checked the standard Run locations in the registry, and then even searched for all instances of lync.exe which is still what runs Skype for Business… no hits that make any sense to it running at startup.

Of course, my next step is to complain on Twitter:

Interesting – Skype for Business runs at user login, but it’s not listed in Task Manager > Startup, or in the registry’s Run locations. The app even has ‘run at startup’ turned off. Not in the Start Menu Startup folder either. Don’t understand what’s triggering it…— Adam Fowler (@AdamFowler_IT) April 12, 2020

No winners in the responses – I checked sysinternaltools autoruns as suggested by Neil Clinch, and Guy Leech had a suggestion on how to completely block lync.exe from running ever, but I still wanted to use Skype for Business.

My Googling hadn’t fared any results, and I was getting desperate. I actually took a chance and read some answers.microsoft.com threads (which are usually sfc /scannow or unhelpful answers that didn’t read the question properly) and user Daniel Wherle had responded to a thread with my exact problem.

The answer was a setting called ‘Use my sign-in info to automatically finish setting up my device and reopen my apps after an update or restart’. This is hidden in Windows 10 Settings > Accounts > Sign-in options. It’s down the very bottom:

After I turned this option off and rebooted, Skype for Business no longer launched at startup. I even launched it manually, and restarted while it was running.

I turned the setting back on and rebooted, Skype for Business still didn’t autostart – that is, until I ran it with the option on, exited and rebooted.

It’s worth noting that even after completely exiting Skype for Business, lync.exe still ran in the background. I suspect this is part of the problem, because it also won’t re-open until that task is killed. I don’t have any other Office apps open, and it seems like a common enough problem that others will hit it – maybe with other programs too and this Windows 10 option enabled.

A strange one, but probably as far as I’ll dig on the issue.
