Hi Jesse W.,
Are you experiencing this in the Intel XDK app or on apps you build? If it's for apps you build, consider including this in your project, as Microsoft has restrictions on manipulating the DOM in Windows applications.
Jesse -- if it's the XDK home screen you're referring to, and you updated to Windows 10 while the XDK was already installed, it sometimes helps to download and reinstall the XDK. You do not have to uninstall, just download from http://xdk.intel.com and reinstall.
