I recently installed Windows 10 Professional version, and I'm having issues with permissions after doing so.
I initially installed with my Microsoft Account, which seemed to cause quite a few issues (slow loading, Outlook troubles, etc). I switched to using my original local account, and now I am get constant "Access denied" error messages when trying to save documents to the My Documents folder (and other places). The user I'm logging in with is a member of the Administrators group, so I should have permissions to save files pretty much anywhere, and certainly in My Documents
I've found that giving the HomeUsers group Full Control permission to a folder resolves this - but I shouldn't have to do that, since my login is a member of the Administrators group.
I realize I can just go down the list and reset all the permissions for every folder, but I'm curious why this happened, and also why my Administrator-level permissions don't allow me access to those files and folders?
