My apologies, I have all three apps and have not noticed any change most probably because I have the fulkl Office suite installed and connected to my Office 365 account. When the apps were in Preview stage, when this tutorial was written, all you needed was an MS account.
If this really is a case, Office apps now requiring the O365 subscription, I will edit the tutorial accordingly.
It's a good thing that swarfega noticed and posted, I almost forgot to install them(they are free and can be used in read only) to make changes one can use the online version, or like me LibreOffice in "Microsoft mode" as I call it from the settings one can set. I don't write much so for viewing on a daily basis, these apps are still very useful. For example viewing the Excel listing of the Windows 10 Video Tutorials(yes that was a plug people)
OK, the tutorial is edited and this note added at the beginning of it:
NotePlease notice that the Office Apps in Windows 10 require an active Office 365 subscription. You need to sign in to Windows with an MS Account in order to be able to install the Office Preview apps. They won't install when using a local account.
When installed, you need a Microsoft Account to use the apps in Read Only mode to read and view Office documents. To edit and create documents with Office Apps a valid Office 365 Home, Personal or University subscription is required.
Thanks @swarfega for pointing this out.
Office 2010 64 Bit is working just fine for me.
