Upon connecting the Sony Xperia ZR phone or even an ordinary pen drive to the Windows 8 computer, I found that it shows a window that says Installing drivers… This is strange, because when I connected the Sony Xperia ZR to the Windows 8 computer, it detected the storage and showed it all correctly in the File Manager.
Unfortunately, the message never went away for about 2 hours and googling around, I found that there is a DSMService that attempts to find drivers for the phone on the Microsoft servers. That is absolutely a waste of time and makes me wonder if Microsoft takes us for fools!
To stop this download, I had to stop the service responsible for it in the first place. Start up Task Manager, go to Services and Stop the service DSMService.
