A few weeks ago after a reboot on one of my Win10 machines the apps (MS Office, Control Pannel, Paint, etc) all show up in what appears to be a browser session. In Excel new Workbooks are a new tab. Outlook shows mail to be read in a new tab. I want my applications to be regular win32 apps with normal pop-ups and other controls. I cannot figure our why or how to undo this. Any help is much appreciated. Here is what Outlook looks like in this environment.
