Today, I decided to clean install windows 10 version 10586 in a virtual machine (using vmware player), so I could use it to test Insider versions (I had a spare 8.1 retail licence to activate it).

It all installed fine, but the really strange thing is I did not enter ANY account information ie MS account or any local account information, but it set up an identical local account to the account I use as my main account on the PC, even without any password.

I cannot for the life of me see how this or why this happened.

It is as if vmware player picked up data from my main OS, and used it automatically?
