I have installed the Windows 10 Insider Program. Everything works, except Apache. When I try to start it, it says that port 80 is blocked. Is there a way to unblock it or tell Apache to use another port instead?
I was using Windows 7 before. I had trouble with port 80 with skype, but i have disabled it.

Type in command line
netstat -aon | findstr :80
You'll see PID of process which uses port 80. Then try to configure this app to use another port, or just kill it
UPDATE: I'll write my comment here to be more clear: according to this link, in Windows 10, it is the MsDepSvc service which occupies port 80. It's for IIS or Web Matrix 2. If you will not use IIS or Web Matrix 2 for any web development, you can try shutting down the service
And for the second part of your question, you can tell Apache to use another port by editing [Apache folder]/conf/httpd.conf. It has "Listen 80" string. Change 80 to whatever free port you want and reload Apache

In case you need to run IIS on port 80/443 but on different IP address, you may use netsh http add iplisten xxx.xxx.xxx.xxx as described here:

Shutting down "some system process" may be tricky... you should rather edit the [Apache folder]/conf/httpd.conf as mentioned by @Sergey Maksimenko and if you want to configure virtual host, use the new port in [Apache folder]/conf/extra/httpd-vhosts.conf (I used 4900 instead of 80 and 4901 instead of 443 in [Apache folder]/conf/httpd-ssl.conf). And remember to use the port when accessing page on localhost (or your virtualhost), for example: localhost:4900/index.html

This answer is intended as an addendum to the highest rated answer on this thread by paaacman. I just wanted to add some helpful detail for users like myself who don't know their way around Windows 10 as well.
Windows 10 runs IIS (Internet Information Services, Microsoft's web server software) automatically during Startup on Port 80. In order to use Apache Server on that port, IIS must be stopped.
paaacman's response refers to the IIS server as "W3SVC", or the "World Wide Web Publishing Service". I suppose that's because Windows 10 runs IIS as a service. In order to disable it or modify how the service runs, you need to know where to find "Services" in your system.
I found the easiest way there was to click on the search button next to the start menu button in the Windows 10 taskbar and type "Administrative Tools". You can either hit return or click on the "Administrative Tools" link that Windows finds for you.
A control panel window will open with a list of tools. The one you want is "Services." Double-click it.
Another window will open called "Services." Locate the one named "World Wide Web Publishing Service." Some other users in this thread have listed what it is called in other languages, if your list is not in English.
If you only want to turn off the IIS server for this Windows session, but want it to run automatically again the next time you start up Windows, right-click "World Wide Web Publishing Service" and choose "Stop." The server will stop, and Port 80 will be freed up for Apache (or whatever else you want to use it for).
If you want to prevent the IIS server from running automatically when you start up Windows in the future, right-click "World Wide Web Publishing Serivce" and select "Properties." In the window that appears, locate the "Startup type" dropdown, and set it "Manual." Click "Apply" or "OK" to save your changes. You should be all set.

I know this MIGHT not be the cause of your issue, but I've spent a few hours hitting my head against the wall to solve this issue and this is my solution.
(running Windows 10 x32)
So I had installed XAMPP in a deeply nested directory and all the conf files make reference to root\xampp\apache, whereas my files were some_dir\another_dir\whatthehelliswrongwithme\finally\xampp\apache
so my options were to either go through and edit all \xampp\apache references and point them at the right place, OR, the much simpler option... reinstall XAMPP at the root, so the references all point to the right place.
A little annoying, but I guess that's what we get when Mac and Windows try to be friends..
Hope it helps a few of you.

Beside the quite obvious reason (IIS), there is another reason that is common enough for this problem. It is worth to quote this question and its answer here:
http://stackoverflow.com/questions/22994888/why-skype-using-http-or-https-ports-80-and-443
So, if you have Skype installed in the computer, be sure to check this as well. The solution is quoted here:
To turn off and disable Skype usage of and listening on port 80 and port 443, open the Skype window, then click on Tools menu and select Options. Click on Advanced tab, and go to Connection sub-tab. Untick or uncheck the check box for Use port 80 and 443 as an alternatives for incoming connections option. Click on Save button and then restart Skype to make the change effective.

With Windows 10 IIS runs on Port 80 by default which can be changed:
Run appwiz.cpl use Turn Windows features on or off and install the IIS Manager Console.
Run InetMgr.exe and go to "Connections -> Sites" and open with right-mouse click the context menu on the default entry "Default Website". In Context Menu select "Bindings" to open the Server address and port configuration.

I know that maybe this problem was resolved but I had the same problem with different solution. For that, I am going to explain another possible solution. In my case, the port 80 was occupied by Skype (pid: 25252) and I did not know what programme was.
To see the program's pid which is using the port 80 you can use the command that other people said before:
netstat -aon | findstr 0.0:80
To kill the process using the pid (in the case that you do not know the programme) you have to open the CMD with administrator permission and use the next command:
taskkill /pid 25252
Other options with this command are here.

In my case I need both XAMPP for Apache development & IIS Express for .Net 2013 development; so I do the following:
In Command Prompt typed services.msc, this loads "Windows Services" where I located "World Wide Web Publishing Service" and stop it. World Wide Web Publishing Service STOP
The I start XAMPP Control Panel click on "Config", then choose "Apache httpd.conf". Search for "80" then change that to "8080" in both "Listen 80" and "ServerName localhost:80". Save the file from "Save As" & choose "All files" to not save it as text from "Save As Type" & the "Encoding" should be "UTF-8". Apache httpd.conf
Quit XAMPP Control Panel, then start it again and from "Action" start Apache & MySQL. Now you will see the port changed. As you know now you have to get to your Apache server by using "localhost:8080" instead of "localhost". Also you have both Apache & IIS Express running in the same Windows 10 PC.
I read a post some where were the writer suggested to use port "9080" but it did not work for me.

While many are taking the approach to stop/disable IIS, it may be helpful to know that you can simply modify the XAMPP port, which has been answered here. This is the route I had to take as I need both running.

I had the same issue and none of the above solutions worked for me.
Apache uses both ports 80 and 443 (for HTTPS) and both must be ready to be used for Apache to start successfully. Only port 80 might not be enough.
I found in my case that when running VMWare Workstation I had the port 443 used by the VMware sharing.
You have to disable sharing in the VMware main Preferences or change the port in this section.
After that as long as you have no other server hooked to the port 80 (see above solutions) then you should be able to start Apache or NGinx on XAMPP or any other Windows stack application.
I hope this will help other users.
I had the same problem on windows 10, IIS/10.0 was using port 80
