Like most people we all have VMware workstation on our laptops so that we can test new software or changes before going live. Recently my company enabled Credential Guard/Device Guard and it stopped my VMs from powering on. There is an article from VMware which documents how to turn off Credential Guard/Device Guard which works like a treat. Do follow all the steps especially if you have bit locker enabled on your laptop. If you don't remove Hyper-V correctly then you will get the famous blue screen.

Update : The VMware KB article now refers you to this Microsoft article where it guides you on how to turn on/off Credential Guard manually or via a powershell script which you can download. Please remember if you are running this fix on a workstation that has domain GPO applied then you may need to check with your GPO admins that they are not re-applying the credential guard settings again via GPO.
