I have a Sony Vaio 32 bit machine 4gb RAM.
It gets stuck at about 80-84% when updating then it says "Couldn't update to Windows 8.1 - 0xC1900101 - 0x40017"
I haven't ever been able to find decent info on the actual microsoft site. I have no devices plugged in, no partitions, etc. Why is this happening! Any work arounds? Would it be better to just burn the ISO and try it that way? But isn't that supposed to be the beauty of the "store" so I don't have to do that?
