How do I get access to Excel Lambda functions?

New Contributor

I believe I am set up to have a copy of Excel which supports Lambda functions. 

When I try to use it, it is not available. What am I missing?

You are on Current (Preview) channel, it shall be Beta to work with lambdas.

Thanks Sergei.
How do I switch to the Beta channel? The Office Insider has me signed up for Beta, I cannot see how to change the 'About Excel' from 'Current' to 'Beta'.


There are few ways, registry key includes, but I'm not sure which key is valid now. Microsoft removed that from their site month or two ago.
