We all lose track of our phone from time to time and now you can ask Cortana to find your phone, regardless of device, on your PC using the new find my phone feature. The feature will allow users to locate their phone from their PC through geo-location and by having Cortana ring your phone. For more tips like this, check out the working remotely playlist at www.youtube.com/FoetronAcademy . Also, if you need any further assistance then you can raise a support ticket and get it addressed.
