Unable to install IIS on Windows 10

Question

I just upgraded my Windows 8 machine to Windows 10 yesterday. I did not have IIS installed at the time (though I've installed it with ease on other machines in the past). I was hoping it would once again be easy, but something seems wrong with Windows 10 and IIS.

I went to Control Panel > Programs > Turn Windows features on or off. I ticked the box for Internet Information Services, and hit OK. The first time I tried this, everything looked like it was going well until it popped up some error dialog (the text of which I cannot recall at the moment). So I did some searching and found a forum post that recommended to run this command from the command line:

dism /online /cleanup-image /restorehealth

So I gave that a shot (had to do so from a Run-as-Administrator command line), but that got to about 20% and then just stopped moving. So I rebooted the machine and tried from Control Panel again. Now I just get an infinite progress bar inside a window labeled "Windows Features" that says "Searching for required files." It just moves from left to right over and over again, nothing ever happening. How can I get IIS installed in Windows 10?

EDIT: That dism command finally finished! Here's what it said when it finished:

The source files could not be found.

Use the "Source" option to specify the location of the files that are required to restore the feature. For more information on specifying source location, see http://go.microsoft.com/fwlink/?LinkId=243077.

The DISM log file can be found at C:\WINDOWS\Logs\DISM\dism.log

Answer 1

Wait... it seems to have resolved itself. My apologies. What I described as an "infinite" progress bar was, in fact, finite. It eventually finished, and now IIS is there.
