My machine runs IIS 10 - it came without my knowledge during an upgrade from Windows 7 (as mentioned in Windows 10 upgrade come with Internet Information Services 10?) - now I wonder: Is it safe to disable/turn it off temporarily or even uninstall it permanently, or are there any (life supporting or not) services which require it? If there's no straightforward answer to that, how may I find out?

  • The Windows 10 Upgrade does not install IIS, unless IIS was already present on your Windows 7 system. If you don't need it anymore, uninstall it. Aug 3, 2016 at 16:59
  • @PeterHahndorf Do you have some evidence for that statement? "IIS 10 is included in Windows Server 2016 and Windows 10" from en.wikipedia.org/wiki/Internet_Information_Services and blogs.iis.net/davidso/http2 suggest otherwise...

  • @DavidPostill - Of course IIS is included in Windows 10 and Server 2016, but it is not installed by default. And the upgrade process from 7 to 10 doesn't just install it. If you want IIS you have to enable/install it. Aug 4, 2016 at 13:43
  • @PeterHahndorf, if there was IIS10 on my machine before the upgrade, at least it wasn't launched by default on system startup, yet now on a fresh Win7->Win10 upgrade it does Aug 5, 2016 at 8:28
  • @HumanInDisguise - I have no way to test that, but I agree the 7 to 10 upgrade does change some configuration settings. Aug 5, 2016 at 8:53

Unless you're running a web server of some kind, you don't need it. Nothing inherent to Windows depends on IIS.

You can disable it via Programs and Features -> Turn Windows Features On or Off.

Add/remove IIS Feature

  • Thanks, this helped. Eventually, just when unchecking the checkmark on IIS a popup asked me to confirm if I wanted to deactivate three services which depend on it: named-pipe-activation and two other activation ways whose names I omitted to record. I've confirmed the checkbox, machine still works well. Just FYI for whoever reads this in the future. Aug 5, 2016 at 8:52
