@adityapatwardhan may need to update the PSVersionTable there.

Customers are hitting this. Repro with PS7 Preview.3:

Get-EventL<tab>

Expected nothing to match

Actual completes Get-EventLog which is in WinPS Mgmt module. Of course running the command returns a "command not found" error.

I'm also running 7 preview 3 and can't repro this. Windows PowerShell resolves and executes the command, but I get no tab completion for it in PS 7 or 6. That's the reason this issue is still unresolved -- we haven't seen a clear repro of it. If you're able to get this tab completion to happen with a from-source build, we can debug it and find out what the issue is. But I suspect it has to be on your machine and may be a question of system state (my chief suspicion is that this is a cache issue).

With @SteveL-MSFT repo above I only get the tabcompletion result when WindowsPSModulePath has been imported into the session in 7-p3

Otherwise on a new session it doesn't tab complete

Running @rjmholt original command returns nothing in either state for me

[rjmholt]

Ah - with the Windows PS module path at the end of the PSModulePath? That might mean the problem lies in being able to discover the command but not load the module because the 6.1 version is already loaded

It loads the module (Microsoft.PowerShell.Management 3.1.0.0) behind the scenes:

Also, this line is misleading and unwanted for the missing commands:

The WinPS compat feature in PS7 resolves this
