Hello all,  Got a brand new  Dell PC yesterday with Windows 8 Pro 8.1 including the update 1.  The weird thing is still boots direct to the Metro start screen is this the way Dell configured the set up?  I thought with update 1 the set up changed to boot direct to the Desktop.   I must say Windows 8 is not as bad as I feared! I have been 100% Linux for the last two years so was worried going back to Windows (Last used Vista).   Thanks Dan 
Windows 8 Pro Update 8.1 Update 1 - Boot to Desktop
