Hi! I tried to upgrade to LTSB 2016 using setup.exe, but "Keep personal files and apps" was grayed out. Is there anything I can do? I just tried using UpDown8 to change edition to Enterprise, but it didn't seem to work. Do I need to reboot? Thanks! (running Win7 Pro x64) Edit: Nope. Just rebooted, and "Keep personal files and apps" is still grayed out.
