So regardless of Win32 or UWP, everything will eventually be sandboxed.
Windows 7 is the new XP.
Win7 is a focal point of some importance: It's where developers who don't want to be pushed into app store indentured servitude join up with the Windows compatible systems, Wine and ReactOS.
Everything before Win7 is not a focal point because it's too old. Everything after Win7 is not a focal point because nobody can handle the update threadmill. By elimination, it's Win7.
Win7 is not the new XP; it's the future of stability-oriented Windows compatible computing.
OpenFile() could be considered deprecated but the official documentation doesn't mark it as deprecated.
You missed the point that these API have been stable for decades and software will continue to work without any change.
"OpenFile() has been deprecated and replaced by CreateFile(), which was superseded by CreateFile2()."
I never said CreateFile() was deprecated. Superseded is not the same thing.

"Note This function has limited capabilities and is not recommended. For new application development, use the CreateFile function."
Looks pretty much an euphemism for deprecated.

Not when Windows puts a container around what they can see.
