Please tell me exactly how to download Win 10 ISO

[loomberah]

I have a fairly new HP Pavilion Computer fitted with Win 8.1. I have backed up all of my files and am ready to begin. I have read a lot about ISO files etc but I need to know exactly how I go about downloading the file to a DVD or similar. Once I've got that then I'll worry about installing the file on my computer.

Choose Windows 10, the first item in the first drop down (not single language at the bottom)
Next choose your language and your bit version (32 or 64 bit to match your system architecture or in the case of an upgrade, to match your currently installed version of Windows).
That will provide an ISO that will upgrade either or both Windows 10 Pro and Home.
Once you have downloaded the ISO you can use ImgBurn to burn it to a DVD http://imgburn.com/index.php?act=download
OR
Rufus to burn it to a USB ThumbDrive http://rufus.akeo.ie/
When you've created the installation media then you simply launch setup.exe from the media from within your current version of Windows to perform the in-place upgrade.
In the case of upgrading from Windows 8.1 as seems to be your situation.... You can simply double click the ISO file and that will mount it as a virtual drive, where you can select and run setup.exe.

I would also suggest that in addition to a file backup you might want to consider performing a disk image.

Thanks so much for that- I'd like to attack the job immediately but I am going on vacation for two week. I'll do it when I return.
