Guys I want to update to window 8.1 frm 8:
There is way to update from iso of window 8.1 (legally) rather than download from window store?
I want to save window 8.1 iso in case i have to reinstall windows.
I assume you have a legal Windows 8 product key.
This is for new installation of Windows 8.1 using Windows 8 product key. Not sure about upgrading an existing installation.
Download the Windows 8.1 ISO / create bootable USB, using the method mentioned here Here is how to get the Windows 8.1 ISO and create a USB install stick - Neowin.
I suggest create a bootable USB.
Now go to the USB, then
source folder.
Create a file named "ei.cfg" there and add the following lines.
Code:
[EditionID]
Professional
[Channel]
Retail
[VL]
0
Now boot from the USB, It will not ask for 8.1 key in the beginning of the installtion. Once the installation completes, use the Windows 8 key to activate it. It works.
