Error Code 0x800072efe

Question

I currently have Windows 8 and I want to update to Windows 8.1. I disabled my Bitdefender antivirus and tried to upgrade to Windows 8.1 and after about 2 hours, I got the message that I cannot download 8.1, and the details said Error Code0x80072efe.  Also, I don't know if I have the needed KB2871389 and KB2917499  updates. What do I need to do to fix this problem?

Hi,

Save your Data and do a clean install of the exact same edition of 8.1 as 8 is.

Windows 8 > 8.1 is a free upgrade released by Microsoft and this is a workaround if you are unable to get it via the Store, etc.

@@@@@@@@@@@@@@@@@@@@@@@@@@

You can download and create your own Windows 8.1 Installation Media to reinstall the Operating System with..

"Create installation media for Windows 8.1"

With Windows 8/8.1 The Product Key on preinstalled Operating Systems (HP, Acer, etc) is embedded in the BIOS in the Motherboard, so that the lost and/or worn C.O.A. Sticker problem is no more.

When you reinstall it will pick up the Product Key and activate the system automatically.

If it does not, follow these steps:
