Downloading it now, have they fixed the issue with the user folder having two folders of everything?
It happened even with a clean install of 10074. Very annoying issue that never happened on earlier builds. Deleting one folder broke the other so that Windows couldn't find it.
Update - I have just done the upgrade via Windows update, checked the user folder and all duplicated folders are now gone, seems they fixed that bug, thanks MS
I did a clean install of 100074 earlier on, and I never got the folder duping bug. I've done a clean install of 10122 and it's not there too. I did have a few different bugs the first few times I was trying to get them to run, but I feel like they were down to the way my computer was behaving being forced to run at 1.199Ghz constantly.
