    If you Google for "DDK_XP.ISO", you will find a bunch of hits that you can download. Details:

    File: DDK_XP.ISO
    Size: 146,276,352 bytes
    CRC-32: 39fb8992
    MD4: f1617ed6c50439844b12696c7e05d8e1
    MD5: add294e46849d80b89c0f67662598136
    SHA-1: 8b844f601963e71fdae3fcd80c89acab2423be1b

    Examining the ISO in a hex editor, you will notice that it looks like a genuine Microsoft ISO, and it has AutoCRC. However, there is junk in the file after the last AutoCRC entry, starting at offset 0x8b2e000. If you cut away the junk, you are left with:

    File: ddk_xp_cut.iso
    Size: 145,940,480 bytes
    CRC-32: ffffffff
    MD4: 6a7a08f4cbeaf4705200ecba3f8c20c3
    MD5: c0dca3443be4d79f1f4b73d250b535cd
    SHA-1: baf312cb543ec8d4156ad66c4be5cbda32825621

    You can see that the CRC-32 is now the expected ffffffff as for a genuine MS ISO with AutoCRC. I therefore have a high confidence that this cut version is the original Windows XP DDK ISO.

    May be the junk is nothing but padding data.

    The junk is mostly zeroes, but there are a few non-zero bytes here and there, which is what's throwing off the CRC-32. So yes, it's padding, but it should be cut away.

    Also note that CRC-32 can be adjusted on purpose. So a skilled, malicious person may have altered files in the ISO, this is not a guarantee that it's an untouched ISO, just very likely. Won't know for sure until the SHA hash can be dug up from somewhere (Googling it gives no result).

    Indeed, you are right. Didn't know that.

    Also, refering to another iso

    File: 1830_usa_ddk.iso
    Size: 242,141,184 bytes
    CRC-32: ffffffff
    MD4: AD57FDB5D723E898CE6DD1BFA16305C9
    MD5: E9193A1E80C3DD13B66AF81D4FBB9369
    SHA-1: 0D2154D88A5EE252CC908630C77863BB42777387

    this is another official image.

    You should be able to use it for XP as well, and since there is a direct download link from Microsoft, you can trust it's original.

    Which one ?

    Also, if anyone have other than WXOPK_EN.iso and VRMOPK_EN.iso releases please, upload somewhere.
    Thank you.

    I think you are good with this OZ, just your file name is different. WXOPK_EN_SP1

    Thanks EFA11, grabbing it right now. Much appreciated. :worthy:

    EDIT:

    I guess in theory there could be a SP1a and a SP2b as well, but never seen them mentioned anywhere.

    This thread confused me, especially with Oz deleting some of his posts. Which one is the correct info for VRMOPK_EN.ISO?
    This one from page 1:
    or this one from page 2:

    @ kelorgo

    Ups, did a copy paste of wrong one, correct one is in the svf file.
    Deleted a post to avoid confusing people, just made it worse.
