There are some things you cannot do on a typical Windows 8.1 installation such as view a web site externally when running IIS Express. But also if you want to run full IIS on a Windows Pro 8.1 machine and have Visual Studio run your web application through it then you need to run Visual Studio with administrator privileges. In Windows 7 there is a compatibility tab in the program properties where you can specify this, but that is not available in Windows 8 or Windows 8.1 installations. So find the location of the devenv.exe application file. This is usually somewhere like C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE.

  Right click it and instead of choosing properties, choose troubleshoot compatibility.  
vs_runas_admin_2
Select Troubleshoot program for the options  
vs_runas_admin_3
Then check the box for additional permissions (this usually means administrator privileges).  
vs_runas_admin_4
Now test the program by running Visual Studio  
vs_runas_admin_5
Once Visual Studio has opened, at the top it should specify that it is running as administrator  
vs_runas_admin_6
Back to the wizard, choose 'Yes, save these settings for this program'  
vs_runas_admin_7
It will do its thing and look for any other issues.

You should see the next image when it has finished off.

Simply close it and you should be OK with running IIS Express as well as a local installation of IIS.  

Windows 10

Right so I got the name completely wrong in my last post, I will admit that straight away; talk about a curve ball. I have been having a play around with the technical preview of Windows 10 and I am liking it a lot. I believe it is definitely an easier migration path for enterprise users still on XP. Is the reason why Microsoft went from 8 to 10 because of the theory that enterprises have a tendency to miss out on a release when doing their client migrations. So going from XP to Windows 7 and missing Vista and going from Windows 7 to Windows 9 or in this case Windows 10. Who knows.

Charms are still there in Windows 10

There was a rumor going around in the software development community a while back that Charms will be disappearing in the next Windows release. As this image shows, they are still there.

  However if you have a Store app open on your desktop and use the same key combination of Windows+C, then you also get access to a lot of the same functionality within the app.

Why is this such a big deal

If you are developing Windows store apps, you need to be sure that what you are coding will be supported in future Windows releases. If you are adding functionality that allows your users to change app settings, they would now be accessible from both the Charms and context menu in the app. Maybe the Charms will disappear by the time Windows 10 gets its full release some time in 2015. At least this way all that work doing app settings fly outs will not go to waste. The other option would be to add the same functionality to a bottom menu in the app, similar to what you do in a Windows Phone app.   Happy coding
