I remember seeing one of these ISOs some years ago, so I decided to Google for them. The only result I can find is a torrent with 1.5TB that includes English and Russian ISOs for almost all Windows since 1.0 to NT 6.3, each ISO as a SHA in the same folder. I managed to get the SHA for these: Code: 421d69a526668fe2141b10adec817bc8247d6ae8 en_winxp_home_with_sp1.iso 522.8 MB bf300c3f204900479e190ffcb18936838e4cc870 en_winxp_home_with_sp1_oem.iso 522.8 MB c45875cb3b9ac8bface936625fd4433f0898364a en_winxp_home_with_sp1a.iso 518.8 MB 2e0ecac222a13b4b0ccb609500106a406d2f3c8c en_winxp_home_with_sp1a_oem.iso 518.8 MB 02695740d94ffb094fc3e80a7111c9501d534f6d en_winxp_pro_with_sp1.iso 539.6 MB 9bf0e6f57c72a382994df5b419ce99ee8be2deb9 en_winxp_pro_with_sp1_oem.iso 539.6 MB 4d3eb8c01f95a323853f5d1615970b15aaeadbb7 en_winxp_pro_with_sp1_vl.iso 539.6 MB f11f8615131d2d50cf1d7494bc56e133725b28d4 en_winxp_pro_with_sp1a.iso 535.6 MB 3b81152fcf3909af2c4d426a2ea86caea67b7f70 en_winxp_pro_with_sp1a_oem.iso 535.6 MB 6b41c27d9412b6236d996f54c579909899ee4b55 en_winxp_pro_with_sp1a_vl.iso 535.6 MB Are these untouched Windows XP SP1/SP1a ISOs? EDIT: to find such torrent, google for "Microsoft Windows Collection" or any ISO above. Torrent file is almost 4MB in size and crashes uTorrent 2.2.1, so I had to switch to qBittorrent to take a look "inside".
If you google the SHA1 of the files there seems to be a lot of information about that file. For example on a forum I found they posted this about this SHA1: 421d69a526668fe2141b10adec817bc8247d6ae8 Code: 2) SP1 (with service pack 1) Version : 5.1.2600.1106 File Size : 548,194,304 Authoring Tool : CDIMAGE 2.47 (10/12/2000 TM) GMT Code : E4 Volume Name : XRMHFPP_EN Volume Serial Number : 133B-5190 Date & Time : 08/29/2002, 12:00:00 MD5 Checksum : 50682acc2e5a236f012768820fec3dd7 SHA1 Checksum : 421d69a526668fe2141b10adec817bc8247d6ae8 ExclCRC : 0xD3DE449A (00000000 - 0009D7FF) / 0xC14463DE (00000000 - 20ACC7FF) AutoCRC : 0x8E582C9C (00000000 - 0009D7FF) / 0xA5ED7D8B (00000000 - 20ACC7FF) Someone in this forum worked with Windows XP SP1 files. forums.mydigitallife.net/threads/59388-xdelta-patches-for-Windows-XP-ISO?p=998209&viewfull=1#post998209 And if you look at the SHA1 of the Volume name of that file it's different. Code: XRMHFPP_EN.ISO / 548,194,304 bytes / SHA1:b273c8d41e3844e3e46722f52f5a4cf9f206c8d0 / Home Edition (Retail Full) Hopefully that helps with your investigations. Conclusion:
Code: File: en_winxp_home_x86_build2600_iso.img CRC-32: ffffffff MD4: 09989a5d94262428d6a83b800f555f77 MD5: be40eeca3a2734773159642997aa50f7 SHA-1: b273c8d41e3844e3e46722f52f5a4cf9f206c8d0 This is RTM with no SP (ie SP0) 421d69a526668fe2141b10adec817bc8247d6ae8 is the SHA1 of SP1 version
I suspected they were correct, just needed a confirmation. This torrent is going nowhere so I found another (different names but same SHA1) that seems to be working, contains RTM, SP1, SP1a, SP2, SP2b and SP3 in OEm/Retail flavours for Home and also Volume for Professional. Googling for "Windows XP English Collection (MS ISOs)" should lead you to the same torrent.
