Windows 10 Pro iso file too large

You can download ISO directly without using silly MCT. English Pro 64-bit is about 4,1 GB.

I've used that before and last month I did get the Version 1607 that was current on the listed date

This is the most recent version of Windows 10, released on 2nd August 2016.

but the Build number was 14393.0. Using the MCT tool a couple of days ago I got Version 1607 Build 14393.442 which didn't take long to update to Build 14393.693 which is the now-current version. I've seen mentioned the possibility of having a new Build next Tuesday/Patch Tuesday.

I think you have an old ISO which only contains Pro & Home. The current MCT version contains 4 versions: Pro, Home, Single and Education hence the file size is 4.42GB.

Yep, you were correct. Downloaded MCT just now, it created ISO file with those 4 versions of Windows 10 in it and would not fit on a standard DVD-R disc, needs a Double Layer disc.

Each MCT is hardcoded to download a specific build, a new one is released each time the current iso is updated. If (as I have) you've still got the older MCTs you can download any iso you wish. I had need of a 10240 one for test purposes a few weeks ago, the original MCT got it for me.

I've always have to keep in mind that a 4.7GB DVD disc is advertised before formatting, 4.2GB being normal. That's why I use the DVD+R/DL discs whenever there's a question about it all fitting. The same is pretty much true for HDD/Hard Disk Drives, always less capacity after formatting.

Hi Folks

Just tested it -- Burns to a BOG STANDARD DVD+RW DVD -- simply used the built in Windows Burn to Disk -- Had to use a USB DVD burner as my laptop doesn't have any optical media.

(Note I used W10 PRO so I didn't have education etc in it so some people are probably correct in the fact that if you have all the components the file is too big for a standard DVD).

I don't have many physical DVD's any more - but I keep the odd R/W one around just in case. If it works on a standard DVD+RW disc it should certainly work on a standard DVD+R.

You don't need dual layer etc. If you can't burn to standard DVD there must be something wrong either with the file you downloaded or in your Workflow. Simply from the .ISO file downloaded or created just Burn to disc using the Windows facility - don't copy / mount it or perform any other operations on the ISO file.

(If you do download the file with everything in it then it WILL be too big - but why do you want the whole kybosh).

I'd suggest though that booting from a DVD is a pain anyway -- might be worthwhile you upgrading hardware so you've got boot from USB as a possibility --there are some great deals on cheap laptops these days and if you "Roll your own" you can get some fantastic deals on mobos etc.

The newest MCT creates the 4 version Windows ISO file which requires a double layer DVD.

I successfully overburned a DVD-R with an oversized windows 10 iso.

Overburning is a luck-based process however, and you may be making a couple coaster before it works.

I did this from Linux, not sure which Windows utilities allow this.


Another option is to use a tool to customize the install.wim and remove a couple uneeded features from the install media. Beware that you can't use the customized install media at work or commercially though IIRC.
