I can’t remember the last time a Sonos PC update for S1 or S2 required a Windows reboot of any of my devices, and certainly not without a prompt. Bizarre.
Same here - no reboot of the PC on any Sonos update S1 or S2. Might it have been a Windows background update and purelyby coincidence, perhaps?
Take a look at C:\ProgramData\Sonos,_Inc\runtime\Installer.log to see if there any clues in there as to why it decided to reboot.
Thanks controlav. I have had this issue for well over a year (maybe two) and I am not the only one who has experienced this. I found this in the log:
MSI (s) (E8:CC) [11:13:13:497]: Windows Installer reconfigured the product. Product Name: Sonos Controller. Product Version: 57.7.19010. Product Language: 1033. Manufacturer: Sonos, Inc.. Reconfiguration success or error status: 0.

I think the issue may be with Windows Installer. I can live with this providing I remember to close everything before updating S1 Controller as there is no prompt that a restart is going to happen.
dcart,
Try uninstalling the S1 controller from your PC, reboot the PC, then install a fresh copy of S1.
My S1 log is notably different for the same version, taken just now (with no reboot):

I have S2. Same behaviour. Anyone figured this out?
I did initially think I had a fix by uninstalling the S1 controller from my PC (Windows 10 Pro, 21H2), then rebooting and then installing a fresh copy of S1. I then got an automatic-with-no-warning-restart on a subsequent update. So what I do now is when I know an update is available, I don’t use S1 programme to update. Instead, I go to the Sonos website and download the new version from there. Updating and installing this way appears to avoid the automatic restart issue (so far). Even then, I make sure all my work is saved and closed just in case before installing an update.

Thanks. I just did the fresh install to see if that will help in my case. I guess I will see on next update. Otherwise, I will follow your example I think. I also noticed I still had S1 installed so I removed that as well. Maybe that will help

This is still happening for me (been a couple of years of this now), but with controller S2. I recently needed to do a fresh install of Windows 10, so I took the opportunity to install the S2 controller on a fresh win10 install. First time Sonos issued an update perhaps month later, I got the same reboot without warning. Happens every time now. Today’s update prompted me to come back here and see if there had been any movement on this issue.
Have you submitted a diagnostic to Sonos after a reboot occurred, and called them? To the best of my knowledge, this is not normal behaviour, but unless you give them specifics, they’re not going to ‘fix’ your issue.
I’m not seeing this issue.
Just joining in to say that every time I also do an update of the Sonos S2 controller my Windows 10 Pro PC does a re-boot without any warnings. It is SO annoying.
I did send a tweet to Sonos about this a couple of weeks ago but they just ignored it.

Might this be something to do with the PC’s ‘Group Policy’ setting for system restarts, perhaps
?
So I regard it as an issue specifically with the Sonos update.
Looking at the Event logs when I started the update the log recorded:
‘Windows Installer reconfigured the product. Product Name: Sonos. Product Version: 69.1.32100. Product Language: 1033. Manufacturer: Sonos, Inc.. Reconfiguration success or error status: 0.’
and at the end of the installation:
‘Windows Installer requires a system restart. Product Name: Sonos. Product Version: 69.1.32152. Product Language: 1033. Manufacturer: Sonos, Inc.. Type of System Restart: 1. Reason for Restart: 1.’
I also notice there were some logs from RestartManager to the effect that ‘’Kaspersky Anti-virus service could not be shut down’
So I wonder if there is some interaction between the Sonos installer and, perhaps, Kaspersky?
Bear in mind that the Sonos installer is also replacing the ‘SonosLibraryService’ background service, which is used as necessary to access music files on the PC.
Still happening. Remove, reinstall, still reboots with no warning. S2 controller.
I’ve just recently updated both the S1/S2 controller Apps on my Windows 10 PC and it didn’t reboot, nor even request a reboot. Even if Windows own updates are installed, Windows OS always throws up a prompt to restart, or cancel, the reboot to finish any such install, in my case. Could you perhaps have switched something off within Windows that may prevent that sort of intervention?
This thread is quite old too, over a year old in fact.
Thx
saw it was an old post, & thought strange.
used to happen, then stopped but recently started happening again.
other updates request permission to restart but Sonos not. If there’s a setting just for Sonos restart request I’m all ears

Not that I’m aware of
I perhaps should add, that I do not use the Sonos library service as my local musuc library is an SMB share on a NAS, so maybe that’s the reason, if your setup perhaps uses a local http shared library? That said, I would still have expected to see Windows prompt you, but maybe switch off/end the Sonos library service before your next Sonos update and see if that fixes the issue for you.
Worth a try. Just an annoyance. But such is life with Windows 
Happened to me just now. I was doing some work and thought ill turn on some music. Bloody Sonos forced my PC to restart without any warning when the controller wanted to update. This has been happening for years and still not fixed. Its the only program that does it - poor programming Sonos. PLEASE FIX IT!

Happened to me just now - again. I don’t use Sonos much on my PC and going through my replies on this account, I complained about it 3 years ago! And its still doing it!!!!!!
