My pleasure!

That feature is currently in the works (officially speaking) for Windows 10; for Windows 7 it already exists (although it has of course been EOL for some time now).

However, I do recall finding a report of someone successfully using WinApps (https://github.com/Fmstrat/winapps) as well as RDP running in a Linux (GNU/Linux) qube to effectively also have Windows applications displayed on a window level. Security-wise it still holds up because that Linux qube, if compromised via the RDP connection, will lead to the disclosure of no additional sensitive information because it's only being used for that single purpose. As long as you have ample RAM to support it, this could work very well.
