I generally use Windows 7 Home Premium in my Acer 4738Z and my old Acer is broken.
so I buy a new Acer E1-410 (and bla-bla in a nutshell) my new Acer E1-410 can't use Windows 7 it must uses
UEFI system (in my previous post http://social.technet.microsoft.com/Forums/windows/en-US/0da6bd1f-ee2c-45c1-91cf-1f1d9d0595f5/how-to-install-windows-7-home-premium-32bit-with-no-legacy-option-in-bios-setting-just-uefi-in?forum=w7itproinstall#cb3f8d18-3d61-41de-8ba3-9eaef87f5849)
So I WRONG ? To buy Windows 8 Pro Upgradeable Only (and before you announce Windows 8.1 Pro)
But FINALLY I can install my new Acer E1-410 in Windows 7 Home Premium (with flash bios to active thier Legacy IDE Boot) and UPGRADE to Windows 8 Pro. (FINISH).
I already ask Microsoft Indonesia by phone to check my product key on windows 8 Pro genuine they said yes it's "only upgradeable" and YES it is genuine.
and finally these my problem:
They said to I CAN FREELY Upgrade to Windows 8.1 by Microsoft Store
so I wanted to upgrade to Windows 8.1 Pro to why not ?? You give me free :) ,...
But without any knowledge how to that (My Windows Store doesn't have store iconto Upgrade to Windows 8.1 Pro).
So I google2xxxx how to UPGRADE to Windows 8.1 Pro
finally I desperate and I download Windows 8.1 Pro ISO (maybe/must be pirate one) from torrent
and fresh/clean install to Windows 8.1 Pro (WITHOUT UPGRADE form Windows 7.1 -> Windows 8 Pro)
OFCOURSE !!! I KNOW IT CAN'T BE ACTIVATE with my older Windows 8 Pro Product Key
So i ask you :
1. What are the disadvantages if I NOT activated my Windows 8.1 Pro ?
2. It's true i can uses all application (on desktop) without any disadvantages ?
