> upgrade windows

Ok, that explains this and the above comment. The last time I had to restart anything to apply an OS update was when I moved to a new RHEL LTS version, the lifespan of which is about 10 years. And there are many ways to do similar GNU/Linux upgrades without a restart at all.

Does Windows Server really need to restart for updates like normal Windows? If so, that's hilariously crap and I'm glad I've never had to touch it.

Edit: not saying a single VPS is fine if it's GNU/Linux, just remaking on the "restart to update" thing they mentioned

> to handle deployments and upgrade windows transparently

GP might have meant "upgrade: Windows(tm)", or he might have meant "windows of time which we have allocated to upgrading the server", and on my first reading I interpreted the second without a single shred of thought towards the possibility of the first.

Most people have to apply patches and if they don't install kpatch, there is generally a restart required to make sure everything is using new versions.

Yes, you can restart all the services that probably slightly less downtime to full reboot on most VPS these days.
