Uninstall Modern App Skype From Windows 8 http://snapvoip.blogspot.com/2014/10/uninstall-skype-from-windows-8.html
I am not a big fan of Skype but it was around with my colleagues and myself sometimes just to experiment with. But the entire crowd are in unison when they describe what Windows 8 has done to the Skype, or the Skype App. Most Don't like it.
Again sticking to the tradition, uninstalling Skype is a task again, whether one wants to get rid of it, reinstall it or get the full desktop version of the Skype (yes there is such a thing, link below)
In order to uninstall Skype from Windows 8;
First of all launch a Powershell as an Administrator;
To run Powershell with Administrator permissions ("Run as administrator")
On the Start screen, type PowerShell, right-click the Windows PowerShell app tile, and then, in the app bar, click Run as administrator.
Move the cursor to the top right corner of the screen, click Search, type PowerShell, right-click the Windows PowerShell app tile, and then, on the app bar, click Run as administrator.
At the Windows PowerShell command prompt, type:
Start-Process PowerShell -Verb RunAs
The most important part is 'PackageFullname' of the app, highlighted above and your version numbers may be different.
Now we have to get the app uninstalled with the command
Next, type Remove-AppxPackage 'PackageFullname', replacing 'PackageFullname' with what is in your Powershell window, like I have typed below for the version appearing in this Powershell window;
(I have made the text small trying to fit all in a single line)
But the most important part is that you type 'PackageFullname' as exactly as it appears, without adding any extra spaces etc. You can highlight the text you want to copy, right click, select copy and right click again and paste in the right location.
That is it, you are done. From here on, you can do what you like, reinstall the modern app, install the desktop application or find another solution for your communication needs.
If you get any error, please retrace the steps again carefully. Run as an Administrator is the most important followed by the correct 'PackageFullname'.
