The 8.1 upgrade has failed for a bunch of people (similar to how SP1 failed for Win7) and now they are left unprotected from new exploits entirely?
I suppose when they get a virus that hoses their system they can use 8.1 media to re-install their system...oh wait, 8.1 discs won't accept Windows 8 product keys for some bizarre reason even though 8.1 is a free upgrade? They have to reinstall Windows 8 and then use the store to upgrade to 8.1 and pray it doesn't fail this time around.
I feel Microsoft have made some strange decisions regarding 8.1, I work at a computer store and when the OEM keys we get are for Windows 8 you have to install 8.1 using a generic KMS key and then use 'slui 3' to enter the customers Windows 8 key after install. Where's the logic in rejecting the key for the install media but then accepting it for the activation?
