    after integrate sp1 for win7x64..why the win7x64sp1 are not support UEFI boot ??? test 64 bit Windows 7 DVD is support UEFI to modify????

  2. Eric Buist says

    Eh no, non-working as well. Requires USB keys. It seems I will REALLY have to give up on all my backed up data just to turn my USB sticks into installation media. Windows is evolving in a very bad directions, to the one of constraints and restrictions, requiring people to order more and more and more and more and more parts and devices, and wait longer and longer and longer to get them. I am tired, about to give up and stop using these damned computers.

  3. admin says

    Sorry for not detailing more about ISO file and setup files. Since you have Windows 7 DVD, copy all the contents of the DVD to a folder and then select that folder as setup folder. Hope you got my point.

  4. Leifur says

    I am very disappointed at the start of this Slipstreaming tutorial. It states to select ISO or OS setup files, assuming one knows where and what these ARE!! All I know is that I have a 64 bit Windows 7 DVD and an installation from it. You have jumped ahead or skipped a logical step, like WHAT and WHERE these are FOUND? I put in my Microsoft Disc to start the slip streaming but no ISO there. Can we make it clear and simple at this point ..I am confounded and cannot continue. Do you mean the ISO of SP1?

  5. TeZZa says

    This software is just god awful.
    It is excruciatingly painful to use, if I had a gun I genuinely would have blown my brains out rather than proceed further.
    I tried to using the 64bit version using the download link.
    Every time you click on something you get this lag and the title bar says ‘program not responding’, this is out with the main event!
    There’s rarely a time when you get any feedback as to whether it’s doing anything either, you just have to wait and hope the next prompt appears.
    There was no Slipstream Service Pack Option , when I tried.
    Couldn’t re-run to start the process again, so had to close the program down.
    Then it goes to run a very lengthy ‘Cleaning’ Process on exit without asking.
    This software had no Service pack slipstreaming capability contrary to the guide above!
    Release candidate my bum, this needs to go back to alpha.

  6. JP Cunard says

    ‘We recommend using RT Seven Lite v2.0 and above only’ The link points to a version, doesn’t say which nor does the software itself WTF ???

  7. I Me My self says

  8. wolf says

    hey there

    after slipstream is on 100% i get an error that says service pack not installed succesfully
    can someone help me

    greet wolf

  9. werner maes says

    This does not work when integrating the 64-bit SP1 on a 64-bit Windows 7 machine.
    I always get: “Service Pack not integrated succesfully”

    I use version 2.6.0 of R7 lite

  10. ISI says

    “What is I’ve done wrong? After I apply for “Make Iso” and browsed for the file destination, it works for 2-3 seconds and get a notification that the image was done succesfully, but no image file had been created!!!!
    I’ve tried several times!!!”

    Well just forget it mates. SIMPLE!! Save the files on the DESKTOP then it will work perfect, and do not ask why… I can’t understand the reason that ONLY works saving the files on the DESKTOP…

  12. PCNerd says

    Admin…..THANKS SO MUCH! You created a great application and I really appreacite your efforts.

  13. Gwandad says

    I got the same as 29 above “then OS Selector comes up:
    selecting win pro
    activating the “Slipstream” option
    selecting the win7sp1 package
    it starts with the integrating and finish (after about 10 to 15 minutes) with the message “servicepack is not integrated successfully. ” I only tried twice. Nice looking program. Pity it doesn’t work for me. Thanks anyhow.

  14. Henrik says

    Sorry I take that back… Just found out that the newest version of RT 7 lite actually does support Windows 7 Enterprise edition… Sorry 🙂

  15. Henrik says

    Does anyone know why RT 7 lite doesn’t support Windows 7 Enterprise edition?? – And yes I know it’s a company version.

  16. Tom says

    Tried to Slipstream WIN7x32 Pro with SP1. After 1st run of RC7 2.6 Beta, I got the following error:
    “An error has occurred in the script on this page
    Line: 1
    Char: 7
    Error: Invalid Character
    Code: 0

    I’ve created the slipstreamed ISO, but am not sure if it works ok yet. The above error occurs whenver I switch tabs within RC7.

  17. Wilson says

    I got Service Pack 1 Beta installed and cannot uninstall due to cleaning up the backup files…..Can I use slipstreamed sp1 (latest version) to do a UPGRADE install Windows 7?

  18. Stu Kopelman says

    I believe i am being misunderstood. My original question was: “I have the Upgrade versions of WIN7 Pro 32-bit and 64-bit. Can I create a slipstreamed sp1 version from an upgrade disk?” I do not have a retail version of WIN7, but an upgrade version of the original Win7. Per/Clarence Post #24, I did not purchase Win7 SP1.
    After I copied the files to the HD from the upgrade Win7 Pro Disk, the files I was looking for were not visible even after unchecking Hidden Files. I could go no further.

  19. Peter says


    i am using the latest beta 2.6.0 to slipstream windows 7 professional german with sp1.

    my doing:
    changing the language of the rt7lite to german
    selecting the os path (DVD)OEM
    then it copies the files to a new folder (definded folder)
    then OS Selector comes up:
    selecting win pro
    activating the “Slipstream” option
    selecting the win7sp1 package
    it starts with the integrating and finish (after about 10 to 15 minutes) with the message “servicepack is not integrated successfully.

    Any ideas how to solve it?
    I tryed several times with the same results.

    Some USB drives and some BIOSes do not support booting from USB sticks. You need to make it bootable follow the guide on this site closely and then copy the contents of the ISO to the USB stick and it should work.

  21. Clarenc E. Williamso says

    Hello Admin: Thank you for the guidance. The slipstream worked very well for the DVD; however, I cannot get a USB windows7SP1 product that boots successfully. Went through the routine four times. Each result showed a success. The files are on the USB drive, but when trying to boot from the USB, boot error message appears and does not boot.
    The DVD does boot fine.

  22. Jeff says

    I can confirm this program doesn’t work. I even contacted the creator and he says to wait for Version 3.0 and that it apparently slipstreams ok but is not saving the image. After I use this program it says successful but when I do a clean install SP1 is not on there.

  23. admin says

    You are right. First copy contents from SP1 DVD to a folder. Then browse to this folder instead of ISO.

  24. Clarence says

    Same inquiry as Stu Kopelman:

    I received the Windows 7 SP1 DVD today. I suppose I should copy the disk to my HDD and at the start of the process instead of Browsing to the ISO Browse to the Folder where the DVD was copied to, but on what do I Browse to in the folder, Setup? 64bit? Please advise Stu and me and others ready to do this slipstreaming.
    Thank you.

    I have the Upgrade versions of WIN7 Pro 32-bit and 64-bit. Can I create a slipstreamed sp1 version from an upgrade disk? Thx

  26. Troy says

    Hello. I have a question.

    I am wondering if the slipstreamed Windows 7 SP1 can be used successfully as a Windows upgrade repair on an already installed Windows 7 (installed on a partition or hard drive from my purchased factory Windows 7 Retail DVD-ROM) that was afterwards updated to SP1 using Windows Update?

    Obviously, trying to do a Windows upgrade repair from my purchased factory Windows 7 Retail DVD-ROM (NO SP1) to fix my Windows 7 SP1 (made by installing my purchased factory Windows 7 Retail DVD-ROM that was upgraded afterwards to SP1 using Windows Update) does NOT work. Reason: I trying to fix Windows 7 SP1 from Windows SP0.

    Using my homemade previous slipstreamed Windows Vista and XP created DVDs to perform a repair upgrade of the already installed equivalent Windows operating system and service pack (from the prospective Windows factory DVD-ROM and updated service pack from Windows Update) has been a failed upgrade repair. What I get is during the Windows upgrade repair process is that the versions of Windows (even if I have the *same* Windows operating system version) is NOT the same Windows version and the Windows upgrade repair process can not continue.

    The only way I know to effectively do a Windows upgrade repair is to have to repurchase another factory copy of Windows 7 but this time having *WITH SP1* to fix my Windows 7 SP1 when Windows 7 has been upgraded to SP1 from a Windows Update.

    I ‘assume’ this may work: If you initially install Windows 7 SP1 to use for your computer from my homemade slipstreamed Windows 7 SP1 and if I need to do at some point a Windows upgrade repair using my slipstreamed Windows 7 SP1 — it ‘should work’ successfully?!?!?

    Please reply.

    KB971033 as well….

    The list is either wrong or this tool needs some work. Can anyone confirm my findings?

  28. Jody says

    I don’t think this works properly.

    According to the list
    KB2393802 is included in SP1. According to Windows update on a machine I just installed rebuilt with a slipstreamed SP1 DVD I just built that KB is not installed!! 🙁

  29. admin says

    Curtis, strange that you outcome ISO 4.9 GB. It should be within 4GB. Try it again. Of course, you can remove some native application using the same tool.

  30. Curtis says

    Thanks for the help on how to do this.

    I have the iso made but mine came out to be 4.9Gb. Is there a way to remove some usless applications and such to make my iso fit on a dvd?


  31. admin says

    Please use version 2.6 and above only. If you are using any earlier version, you won’t get Slipstream option.

  32. Yes son says

    This sux. It doesnt give me that option at the bottom of the os’s to integrate the Service pack. What should I do?

  33. BogdanH says

    The point is, resulting (slipstreamed) ISO shouldn’t be noticeably larger than original (non-SP1) ISO.
    If you’ve seen official MS Win7+SP1 ISO, then you can see, that size is 3.09GB -which is almost the same as non-SP1 ISO.
    And you’ve got 3.6GB? -that’s exactly what I’m talking about.

  34. Nathan says


    What are you talking about? A Windows 7 ISO s almost exactly 3 GB. The SP1 package is 903 MB. After Slipstream, my Windows 7 SP1 ISO is 3.6 GB…. thats over 300 MB difference.

  35. Dane says


    You have taken the wrong program, if you go to the bottom of the download site you can se the 2.6 Beta edition Thats the one with slipstream. 🙂


    You have to get Windows 7 WAIK installed on your Vista if you Google it you will get a direct link to Microsoft where you can download it 🙂

    Best regards

  36. Buck says

    I can’t get RTSevenLite 2.6 to install. Have Vista currently. Want to slipstream Win7 and SP1 so I can clean install.

    Keep getting error: Could not resolve path for shell folder 26.

    I’m very “light” technically speaking – I can follow instructions but with regard to this kind of stuff, I’m out of my element and depending entirely on tutorial. But since I can’t get RT7Lite to install, I’m stuck here at the beginning.

    Any idea what the problem is? How to fix it? OR is there another application and tutorial I could use instead of RT7Lite?


  37. Ovio Egrupov says

    I downloaded latest RT 7 Lite but don’t see option Slipstream Service Pack.I follow these instructions!Maybe anyone ask what is problem?

  38. BogdanH says

    I’ve used above method to slipstream Win7 x64 HomePremium and SP1 (Wave0). What wonders me is, resulting ISO file increased by almost exact size of SP1 package.
    I can remember, that slipstreaming WinXP didn’t increase resulting ISO filesize much -because (I assume) existing files were replaced with those from SP. However, for XP, I slipstreamed directly by using SP “integrate” command (as it seems, MS didn’t provide this command for Win7 SP).
    I assume, that RT SevenLite add all content of SP into resulting ISO and just modifies install routine accordingly.
    IMO, older (not needed anymore) files in Win7 ISO should be replaced by those inside SP. Thus, I’ll wait until (and if) MS provides official slipstream method.

  39. admin says

    Yup. It might take a few minutes to hour! Btw, your can use this tool to slipstream Windows 7 SP1 as well. Make sure you have RTSevenLite build 2.6 or above.

  40. 7ota says

    did you really sure about “Wait for a few minutes until you see the Proceed button.” ? its took 1 hour !

  41. mannerohardy says

    thanks for this guide but i have 1 question about list operating system have more than 1 so you have select win7 ultimate for SP1 about the other version? the other version will automaticlly have SP1 or not?

    i have Windows 7 ALL IN ON (32/64BIT)

  42. Ivan Kolevski says

    Thank you kindly for this great tutorial. I will be definitely doing this once the SP1 goes final. I received internal email regarding the RC availability, but I chose to have full Final SP1 integrated instead. Once again, great tutorial. I’ll probably have to dig up the guide for manual slipstreaming as well 🙂
