Account Used To Logon needs to be different from Logged in Windows User - Help Please

Hello,

I am able to successfully deploy WVD for all of my users who login to Windows 10 dekstpos as a named user.  My RemoteApps load fine and all is well.

The issue comes where we have a number of depot locations where for exmaple they might have 2 or more PCs which all login to Windows 10 as the same domain user (primarily for simplicity, they do not need seperate email addresses and need access to the same OF365 mailbox).

So in these locations in our previous non WVD deployment I would have two or more domain users (dep01-2, dep01-2) which would login and run our RemoteApps.  However when I assign these users to the ApplicationGroups the WVD client refreshes and shows the correct apps, when syncing as the dep01-1 etc accounts.  However when the connection is initiated the REmoteDekstp client is choosing to use the logged in Windows account (which is the same on both PCs) instead of the defined RemoteApp domain users.  I hope this makes sense, I'm happy to explain further.  In short I need to be able to specify a WVD RemoteApp user that is different from the OF365 and Windows 10 logged in user.
