I just found a huge Windows 10 flaw and it has impact on File History, too. All us previous Windows users that login with a Microsoft Account have all noticed how Windows 10 names our user accounts after our Microsoft Account. I just noticed this flaw in File History. In previous Windows versions my account was Keith. In 10 it changes that to keith. After I installed Windows 10, I changed my personal folder on my hdd to that name. The first time before I moved my documents, etc. off my ssd. I renamed and applied and ok'd it. I then renamed it to keith like 10 likes and took ownership of everything. I then pointed 10 to my Contacts, Desktop, Documents, Downloads, Favorites, Links, Music, Pictures, Saved Games, Searches and Videos to my hdd. File History and Windows 10, too are showing 3/4 of these folder in D:\Users\Keith\* and 1/4 in D:\users\keith\*. Huge blunder Microsoft That's just like a Store blunder, I've found. Has any other past Windows 8/8.1 users like myself found that 10 only installs the pre-installed modern app's and not the 8/8.1 apps that still work in 10. That's a huge pain in the neck, that it doesn't install the most rece.nt modern app's that do work in 10, that we used in 8/8.1.
