How to decode Microsoft ISO filenames

Post by mrpijey »

I am making this post in the hopes to both help our members and myself into understanding what the various tags means in an official Microsoft ISO file. Microsoft has over the years labeled their ISO files in various ways and to some it may be confusing what it means.

I am not entirely sure about some tags, these will be identified with a question mark ( ? ), if any members knows what it means please let us know and I will update this post. If any member has any other filename formats, finds any errors or wants to add additional info then please let me know and I will update this information.

This post is not made to list every possible filename there is, only to explain the various tags Microsoft uses. They may vary slightly between products and editions.

For starters I got two Windows 7 ISO names.
--------
Image
  1. Language of the OS. Always two letters (with one exception). Example: en, en-gb, cs, da, no, sv.
  2. Minor version build of the OS.
  3. Compile date of the OS (not of the ISO). Indicates YYMMDD-HHMM.
  4. Platform architechture and target. x86 = 32bit 8086-based, x64 = 32bit 8086-based with 64bit AMD-64 extensions. fre = Free, for end user. chk = Checked, debug version. Examples: x86fre, x64chk.
  5. SKU version. Examples: enterprise, enterprisen, professional, starter.
  6. Full language tag of the OS. Must match (1). Examples: en-us, en-gb, sv-se.
  7. Volume license identifier. Optional.
  8. Upgrade identifier. Optional.
  9. Original equipment manufacturer identifier. Optional.
  10. Matches (5).
  11. Volume label of the mounted ISO volume. Contains various codes to identify language, SKU, volume/OEM and media.
--------
Image
  1. Language of the OS. Always two letters (with one exception). Example: en, en-gb, cs, da, no, sv.
  2. Product name. Examples: windows_7, windows_8, windows_server_2012.
  3. SKU version. Examples: enterprise, enterprisen, professional, starter.
  4. Integrated service pack level. Optional.
  5. Platform architechture and target. x86 = 32bit 8086-based, x64 = 32bit 8086-based with 64bit AMD-64 extensions. chk = Checked, debug version. Examples: x86, x64chk.
  6. Storage media
  7. Update flag. The ISO was updated with some critical patch.
  8. Unique MSDN/Technet image number ID.
--------
Image
  1. Language of the OS. Always two letters. Example: en, cs, da, no, sv.
  2. ?
  3. Single or double layer DVD. DVD5 = 4.7GB
  4. Product name. Win = Windows.
  5. SKU version. Examples: Pro, Pro KN, Ent.
  6. 7 With. Means it's an integrated installation with a service pack. Combined with (7) for full service pack level information. Optional.
  7. Integrated service pack level. Optional.
  8. Platform target. 32BIT = x86, 64BIT = x64.
  9. Language of the OS.
  10. Updated ISO. Base ISO with added KB update.
  11. Microsoft Licensing Fulfillment
  12. Microsoft Part Number as it appears on the physical installation media.

Probably MSDN/Technet listing number, or...

Code: Select all

<AirportsFan> the 7th part is a new way of Part No. that was in old Microsoft CDs

Very informative.
To add (the missing ?):

6: dvd/cd and filesystem, u = udf
7: unique image number on technet/msdn.

You can spot number 7 easy, just look at the latest release of Windows 8 and Windows Server 2012.
They are almost all the same, but can differ between languages, like for example 888346 for nl win8 x86 and 888347 for da win 8 x86.

Well the Windows 8 editions aren't so much the same as they are different in whats in the edition matrix and upgrade matrix.

You could probably easily combine all the editions without having much of a headache with it.

Given the fact that nothing is surprising in the tech universe if you know whats coming its actually quite boring to watch.

Combine all the editions? I am not looking into making some AiO disc here. And as for the differences you can easily see that in my Future Releases thread.

Here are some:

11: Microsoft Licensing Fulfillment
12 & 13: Microsoft Part Number (like the classic one from CD's and you find on like Vista Beta DVD and more products.

7w, in this case just means 7 with.

The last one, it is a bit tricky, since some are combined and others not.

I like this thread a lot. It's always a good idea to have a means of deciphering those filenames. I'll add my two cents: Microsoft Office downloaders from DigitalRiver are typically named with the original Microsoft Xyz-yyyyy part number that you would find on the original installation media. If I may link to a topic for those installers and product part numbers here - http://forums.mydigitallife.info/thread ... post494558 (still requires valid CD key to use, mind you). So, if you happen to own the original media, but it is corrupted or physically broken, or if you don't have a cd drive, you can get the installer based upon the part number on the media.

The topic I linked to is a very valuable resource for computer technicians, especially when dealing with non- en-US versions of Office, since the media is not as readily available, and most customers (in my experience) don't have their original media to install Office from. There's also a list within the same subforum for Office 2007 installers- http://forums.mydigitallife.info/thread ... load-Links

Perhaps 'SW' means Software?

en_windows_7_enterprise_with_sp1_x86_dvd_u_677710.iso was the media refresh version to include hotfix KB2534111 so, u = Updated.

Well, there's several opinions about the _u tag then, which one is correct? Any sources?

Added missing information and updated filename example.

I believe iwanttogohome is right. _u_ only apperas in Windows 7 SP1 downloads from msdn, and msdn says:
"This media refresh includes the installation hotfix described in KB Article 2534111. No other changes have been made to the product."

There are also iso's without _u_, which are published earlier and are removed from msdn. Compare:

File Name: en_windows_7_ultimate_with_sp1_x86_dvd_u_677460.iso
Date Published (UTC): 5/12/2011 2:45:59 PM Last Updated (UTC): 5/12/2011 2:45:59 PM
SHA1: 65FCE0F445D9BF7E78E43F17E441E08C63722657 ISO/CRC: 35511F11

File Name: en_windows_7_ultimate_with_sp1_x86_dvd_619077.iso
Date Published (UTC): 2/16/2011 8:50:22 AM Last Updated (UTC): 2/16/2011 8:50:22 AM
SHA1: 92C1ADA4FF09C76EC2F1974940624CAB7F822F62 ISO/CRC: C2966895

Information from mydigitallife (http://forums.mydigitallife.info/thread ... 8eceeedcf9):

Microsoft has updated all distributions and languages of the Windows 7 with SP1 slipstreamed media to include the hotfix, where the new ISO images downloaded from MSDN or TechNet Subscriber Downloads include a “u” in the file name, or known as Windows 7 SP1-U to indicate the media refresh version.

@JiaShang,

Yeah, then probably the ISO was updated but that hotfix. So "u" means Updated I guess.

SW sounds like a localisation.

SW is not a localisation since all of the ISOs of that particular series has it.

it also have a VL (Volume Licence) tag like my XP SP3/Office 2007 ones:
en_windows_xp_professional_with_service_pack_3_x86_cd_vl_x14-73974.iso
en_office_enterprise_2007_DVD_VL_X12-19574.iso
Windows 8 on mobile devices and tablets is akin to Dr Jekyll: a tortured soul hoping for redemption, On a regular PC, Windows 8 is Mr Hyde: a monster that terrorises poor office workers and strangles their productivity.

This isn't a filename by Microsoft, leaks are usually filenamed after the build tags.
AlphaBeta, stop brainwashing me immediately!

This IS a build tag. The compilation date is March 29, 2013 @ 11:55 PM.

By the way, what does something like "m2" or "m3" mean? Milestone?

Code: Select all

Microsoft Windows 7 (''Windows 7'' 6.1.6608.1) (m2) [English]
Microsoft Windows 7 (''Windows 7'' 6.1.6936.0) (x64 m3) [English]
