Need a LEGAL .iso of Windows 10 Pro - Pre Anniversary Edition for clean install.

New Contributor

Does anyone know where I might find a legal Download of an .iso file of Windows 10 Pro 64 bit that is NOT the Anniversary Edition? Tried it and didn't like it. Like others, external drives not being recognized, freeze ups and the weirdest thing - Bluetooth suddenly dissapeared after installing! Don't know if that was from the OS or not... But I got it back with a driver from ASUS. Plus there was other stuff... Thanks!

Create installation media (USB flash drive or DVD) that you can use to install a new copy of Windows 10, perform a clean installation or reinstall Windows 10.

Before you download the tool make sure you have:
An internet connection (internet service provider fees may apply).
Sufficient available data storage for the download, on a computer, USB or external drive.
A blank USB flash drive with at least 5 GB of space or blank DVD (and DVD burner) if you want to create media. We recommend using a blank USB or blank DVD, because any content on it will be deleted.
When burning a DVD from an ISO file, if you are told the disc image file is too large you will need to use Dual Layer (DL) DVD Media.


You can then download and run the media creation tool

Hey! Great introduction to those trying to install Windows! I'm sure that it will be of use.

And as far as wanting a pre-release...  I found it! Problem solved!

What version were you looking for 1507(RTM), 1511(November Update) or 1703(Creators Update) ?


And which version solved your problem ?



Fyi...Pro is an 'Edition'.  Anniversary is a 'Version'.

Thanks for the clarifications!
The real, underlying problem I have is so strange and bizarre that I went all the way back to 14393 in hopes that it could never contain the same bugs or inconsistencies...

Unfortunately, it produced the same error as The Insider build - as well as the Anniversary. So, finding the earliest version of Windows 10 solved the problem I indicated in the post - which was getting the ISO itself, but It did not, however, resolve the real issue reported here:


This little conundrum must be quite difficult because no one has even replied to it. Do you think that you could take a stab at it?


you may want to check into the SMB settings, and if your NAS supports it changeover to the more secure SMB v3
