My BT folder is 6.27GB (!) in total, but no sign of the Install.ESD file which is said by some to be the main installer... *shrug*I've got 3.67GB in the $Windows.~BT folder & my Windows Update history interestingly has several 'failed' status Upgrade to Windows 10 Home entries from last night.
No sign of any failed updates, and the windows icon in the taskbar just opens the same window it always has. Still says my reservation is active though, which is a good sign I suppose!
Now all we have to do is load up with some popcorn and wait for all the horror stories of failed upgrades or unusable Win10 computers which are sure to start popping up on the web any time now. With so many people getting upgraded, there's going to be tons of terribad experiences, no doubt, and people being people won't wait to trumpet it out for all internet to hear!
