Whats the difference in ISO version numbers?

[spacednow]

I can't find anything on this. I have 2 win 7 ISO's. One is 6.1.7601.17514 and other is 6.1.7601.25740. Anyone know?

Not sure what you mean. Is that the name somebody has given to the .iso file, or is it what you get from querying the install.wim?

- - - Updated - - -

For example, this is the wim info for image 4 ( ultimate) in the last official iso from ms which is called en_windows_7_ultimate_with_sp1_x64_dvd_u_677332.iso
SHA1: 36AE90DEFBAD9D9539E649B193AE573B77A71C83





and here is wim info for image 3 ( professional) after I added some updates to it - you can see the changes to the service pack build with added updates



If I were to bother creating an iso , I could give it any name at all, e.g knootyplum.iso

Though it would make more sense if I named it 7601.25661x64_en-US.iso to reflect the updates included.

I would guess that is what somebody has done to the iso you have

- - - Updated - - -

The official iso files contain an install.wim which has all the images for the consumer editions, as you can see the install.wim of the x64 official iso has these 4 images



- - - Updated - - -

You could check the sha1 hash of the iso named 17514, because that might be an official iso which somebody has renamed.

Then search for the hash number on tinternet.

The iso you have with the higher number has likely been updated by somebody and is therefore not "official"

It was a purchased download...both were. That was the build number that Disn++ listed when I loaded ultimate.
Never mind...Duh. I deleted the other pics I had. I was looking at different ISO's I had made. Apparently the last numbers change when you modify it.

25740 is presumably updated by somebody.
.
You can easily make your own updated versions.

Yeh ...duh. I had mounted both earlier and the numbers had changed. I thought maybe one was a later release and it freaked me out. Thought it might have telemetry in it. I remounted my saved original ISO's quickly and the # is the same.

I'm sorry! But I have to ask.....with an OS that's so "Yesterday" (outdated and abandoned by MS) why are we even worrying about any version of Windows 7.
I've migrated all my 10 systems to Windows 8.1, that had all the drivers and many of the attributes of Win-10, without being so user UN-Friendly.

Besides, Win-7 was always such a bi7sh to install, because it never had the drivers I wanted/needed.
Why waste your time, when 8.1 is so available and installs so nicely with all the common drivers you'd ever need.

Just a thought......

hi
those are the build numbers, the lower the number the older the "version".

Dont know why you paid for it, its available free, have to assume that was for the Ultimate licence --- be carefull dont know how long it will remain activated.

I would run the MGAdiag tool available at MajorGeeks, and copy/paste the results and i'll look it over
