How to uninstall Windows Phone SDK
Windows Phone SDK is included in Visual Studio 2013 now. If you are lucky enough you might have an entry for it in “Programs and Features” which will allow you to uninstall it. Sadly for me, this was not the case as there was no visible way to uninstall it from my system.
One solution that allowed me to uninstall Windows Phone SDK was to navigate to the packages folder that can be found in the Virtual Studio CD or .ISO file then look for the WindowsPhone81SDK folder, or something with a similar name in case the version is different.
Inside you will find some .msi files, simply right click on the files then select “Uninstall”. If Windows Phone SDK is installed on your computer the uninstallation process will begin.
