Thank you, Microsoft, for wasting yet another of my afternoons while I try to sort out problems caused by your insufferable insistence that I store everything on my c: drive. Apparently, with Windows 10, OneDrive freaks out if you are savvy enough to store all your data on a drive separate from the one containing your operating system--and when you try to change the location of this folder (after signing out and "moving" it) and point to the new location, it throws up its hands and says "cannot create a folder at this location." All of this after I had to sort out a sound issue (corrupted sound drivers) caused by Windows 10 insistence on installing "updated" drivers (which happen to be the wrong ones). Buzzards!
Windows 10: Be less productive than you used to be!
