Ok, I have tried autorun.exe, also tried :netplwiz" fixes that others have mentioned, but I still have to use a password, not for first start up, but when computer goes into hibernation....extremely frustrating.  Can anyone tell me what else I can try, apart from removing windows 8.1.  Can I get rid of the email account log in? Not sure how to do that either, Thanks clever people :)

Try those 2 settings:

Go to the "Control Panel".
 Click on "Appearance and Personalization".
 Click on "Change Screen Saver".
 Unclick "On resume, display logon screen".

and

Just head into Power Options in Control Panel, then click the Require a password on wakeup on the left-hand side.
Then click the Change settings that are currently unavailable link
Click Prevent Windows Asking for a Password on Wake Up from Sleep/Standby
