Windows 7 SP1 – Retail and Commercial OEM Download Links

For Dell Systems updated Dell Windows Pro 7 January 2016 Reinstallation .isos are recommended.

The Windows 7 November 2011 .isos from Microsoft are unbranded and can be used with any Windows 7 OEM or Retail License. For OEM Licenses one may skip the product key during installation to begin a 30 day trial and apply their manufacturers OEM SLP post installation to activate Windows 7. Microsoft’s software download page for Windows 7 is however unfortunately non-functional in most cases.

Jan Krohn’s Microsoft Windows and Office .iso Downloader Tool is a utility that essentially fixed the flawed user interface of Microsoft’s software download page allowing the generation of proper download links.

Note the installation media created in this guide will be multi-edition including Starter (32 Bit only), Home Basic, Home Premium, Professional and Ultimate and work with all OEM and Retail licenses:

  • It therefore does not matter if you select a Commerical OEM .iso or a Retail .iso.
  • It also doesn’t matter what Edition of Windows 7 you select.

English File Sizes and Checksums

For Windows 7 – English UK and English US are the same “Language”.

The time and currency format and keyboard or input method can be selected for English UK (International English) or English US respectively:


The Microsoft Windows and Microsoft .iso Downloader Tool generates direct download links from Microsoft’s servers. It doesn’t check whether the .iso you downloaded is complete or not.

For the English .isos the file size is 2,504,372 KB for Windows 7 32 Bit and 3,243,070 KB for Windows 7 64 Bit.

The checksums can be checked with Rufus (which we will use later to make the Bootable USB):

Rufus doesn’t need to be installed. Launch Rufus:

Accept the User Account Control:

Select “Select”:

Select your installation .iso and select open:

Select the tick:

Rufus will now compute the .iso checksums:

Just use the MD5. For an English .iso on this page press [Ctrl] and [ f ] and paste the checksums. Ensure that they match one of the values below:

If there is no match your .iso is unique and thus corrupt. For other languages a google search should suffice to make sure you have a non-unique .iso.

Commerical OEM .isos

Note Windows 7 Starter is OEM only and hence not found as a Retail .iso. It is unknown why there is a 64 Bit and 32 Bit Commerical OEM .iso and only a 32 Bit Retail .iso for Windows 7 Home Basic. This Edition is pretty much OEM only however.

Checking if your System has an UEFI Boot

Power down your Dell and then power up and Press [F12]. For non-Dells you may have to use [Esc] or another Function key [F1-F12]. This will take you to your systems Boot Menu.

If it mentions at the top “Boot Mode" then you have a UEFI BIOS. For Windows 7 Installation:

  • The Boot Mode should be set to UEFI.
  • Secure Boot should be Off
  • Legacy ROMs settings (not shown on the Boot Manager Screen) should be Enabled.
  • Note that early UEFI systems may not have Secure Boot and hence no need for Legacy ROM Settings.

For details in Enabling these settings see Unified Extensive Firmware Interface (UEFI).

If it doesn’t mention at the top “Boot Mode" then you have an older system with a Legacy BIOS.

Creating a Bootable USB

Note all the data will be lost on your USB Flash Drive when you create a Windows 7 Bootable USB.

Insert a 8-32 GB USB Flash Drive, it’ll display under Device. If you have multiple USB flash drives attached ensure you select the correct device.

If you are installing Windows 7 64 Bit, the default settings will use the GPT Partition Scheme. The Target System, File System and Cluster Size will be updated correspondingly. This is the correct setting for computers that have a UEFI BIOS.

For earlier computers that don’t possess a UEFI BIOS you have have to change GPT to MBR. The Target System, File System and Cluster Size will be updated correspondingly. If you are using a Windows 7 32 Bit installation .iso you also have to use MBR but this will be automatically selected:

Change the volume label to something more sensible like “Win7x64”:

Select “Start”:

You will get a warning about formatting your USB, select OK to proceed:

Rufus will make the Bootable USB:

When done it will say Ready at the bottom. Press close to close Rufus:

Adding Driver Support Using the Windows USB Installation Tool

The installation .isos from Microsoft are unfortunately from 2011 and do not have support for USB 3.0 or many storage controllers. If you try and use it with hardware with these technologies you may get stuck here with a non-responsive keyboard or mouse:


Or alternatively here and get:

“A required CD\DVD drive device driver is missing. If you have a driver floppy disc, CD, DVD, or USB flash Drive, please insert it now. Note: If the Windows installation media is in the CD/DVD drive, you can safely remove it for this step.”


To make your Bootable USB usable on up to 6th Generation Intel Skylake hardware you’ll need to add drivers to the Bootable USB.

The Windows USB Installation Tool by Gigabyte adds USB 3.0 drivers and storage controller drivers for Intel and Samsung NVMe SSDs as well as associated hotfixes. It may be found here:

Scroll down until you find it:

Alternatively press [Ctrl] and [ f ] and search for Windows USB Installation Tool.

Download the tool and extract it:

To launch the utility double click the WindowsImageTool.exe and accept the User Account Control:

Check the three boxes to add the drivers:

Leave the Source Path as “None – Add USB Drivers" and change the Destination Path to your Windows 7 Bootable USB Flash Drive:

Select Start:

The tool will mount each index of your boot.wim file, add the drivers and then commit the changes. It’ll repeat the process for the install.wim file:

For a Bootable USB made from a English Windows 7 64 Bit .iso Downloaded Directly from Microsoft.

The process took about 16 minutes in my test.

The boot.wim found in the sources folder of the USB was updated from 160 MB to 189 MB.

The install.wim found in the sources folder of the USB was updated from 2.75 GB to 2.88 GB.

Delete the EI.cfg file

The ei.cfg should be deleted after the Bootable USB is made to allow installation of all Editions of Windows 7 for a Corresponding Architecture.

Open up the USB in Windows Explorer go to the sources folder and look for ei.cfg and delete it.




During installation you will get the option to install your desired Edition of Windows 7:


Standalone Updates for Windows 7

It is highly advised to create an Updates folder on your Bootable USB and to download and place the following updates in it. Also make a text file in this folder and copy the information below so you know what order to install the updates in. Installing these updates immediately after Windows 7 will save you Windows Update hassles due to your installation media being >7 years out of date and embedded with Internet Explorer 8 which is no longer supported.

OEM Cert Collection

If you are using a system with an OEM License (including OEM Downgrade Rights from Windows 8.x Pro and Windows 10 Pro) on a computer manufacturered by a major OEM such as Dell, HP, Lenovo, ASUS, Acer, Compaq, Gateway, Packard, Fujitsu, IBM, MSI, Samsung, Sony or Toshiba you are best to install Windows 7 without a Product Key and activate post installation using OEM System Locked Preinstallation – the same BIOS based Product Activation mechanism of factory settings. Doing so will save you from having to call Microsoft to activate by phone.

I have put together the OEM Cert Collection along with an associated 2 line script to install the Cert and Apply the associated OEM SLP Key. After Installation copy the OEM folder containing the cert and OEM SLP key to your C:\ Drive and then run the script file.

It is available as a .zip file here:

Install Windows 7

To install Windows 7 see Windows 7 Installation in a UEFI BIOS or Legacy BIOS.

European Commission N English Checksums

Previously there were European Commission N Editions of Windows 7. These are slightly less functional Editions of Windows 7 created because the European Commission didn’t approve of Microsoft bundling Windows Media Player and Windows Media Centre in Windows 7. However like the European Commission they are extremely unpopular especially in the Anglosphere. The Windows iso Downloader no longer seems to list N Editions however in the off-chance they are shown you should avoid them as your Product Key is unlikely to work with them.

The European Commission is now wasting time with Article 13 trying to break the Internet a bit like Windows Vista and extreme User Account Control:

  1. There is a mistake in the text, because links for professional and ultimate edition x64 lead to same URL (for Ultimate edition)…

    1. You need to purchase a product key or you can install without one for a 30 day trial.

      If you have a system which came with Windows 7 Home Premium OEM preinstalled e.g. from Dell there should be a COA affixed to the system (maybe in the battery compartment of laptops or computer cover of desktops).

      For more details see Windows Reinstallation Guide/A Clean install of Windows 7:

      You can purchase a retail/OEM Windows 7 Home Premium license from the likes of NewEgg, Amazon etc. and input the product key provided to activate.

  2. I’m going to use your files and tutorials to do clean installs of windows 7 on (3) oem machines this weekend (all machines have windows 7 COA stickers). I figured clean installs are going to be MUCH faster than installing via the oem recovery media, which puts a massive amount of bloatware that bleeds everywhere…no matter how hard I try, I cannot get rid of it all. I’ve already contacted microsoft support, and they said that using the digital river iso’s on oem machines is perfectly fine…as long as the product key on the COA sticker is valid for the windows 7 version on the iso. Thanks so much for putting this together!

    1. Amy ensure you backup the SLP Activation of each install using the ABR program before clean installation see here:
      This will save a lot of hassles with Microsoft Product Activation in particular if the COA is faded. I only have the Dell activation files so this is particularly important if your systems are not Dells.

      Clean installs have always been much faster and efficient in my experience.

      1. I had a windows 7 home premium pre installed on my dell xps l502x laptop.i lost the DVD that came with the purchase and the product key has faded away.after 2 or 3 years i installed windows from “softlay” website because my laptop started to have more virus an started to lag… but it is 30 days trial witout product key.if i follow ur steps , can i get back my original OS

    1. Microsoft has a free tool that will help you make the recovery media for either 8 or 8.1………you have to have the product key or you would have had to make a system image prior to this or your machine would haved had to shipped with 8.1 pre installed

    1. Use the Home Premium or Professional 32 Bit version and create a bootable USB.
      Once the bootable USB is made delete the ei.cfg file. The ei.cfg will select the version to install automatically and deleting it gives you a screen presenting you with the option to install Starter. This is explained in more detail above.

  3. Would the pro install be fine for installing on a brand new hard drive on a HP Probook (6560b)

    1. If you are trying to perform downgrade rights then you need installation media with HP system locked preinstallation as no Windows 7 key is provided for downgrade rights. I have these for Dell systems listed here

      For HP I have the files for Home Premium and can probably make these up for Professional and Ultimate from that (I have not uploaded these yet and these are untested).

      If the system has a Windows 7 Professional COA included then you can use the 25 Digit product key on that and manually activate via phone.

  4. I bought a new Dell Windows 7 Professional 64-bit SP1 installation DVD on eBay. The intended recipient PC will not boot to it. I can not open the CD. I have three PC’s running here. They don’t recognize it. What easy step have I missed?

  5. This is an E521. Oddly, it has a Vista sticker but XP OS. Just as when I try to boot to it, when I try to read to it in Explorer, the DVD drive eventually just flashes and everything stops.
    OK now get this. I have a ten year old Compaq Presaro with XP. I push in the disc and it says blah blah your PC isn’t up top specs for this OS. But I can read it in Explorer, see the folders and everything.

    1. Okay so you have a Windows Vista Business COA with downgrade rights to Windows XP. Firstly did you get a new product key with the Reinstallation DVD, if not you should know that the System Locked Preinstallation key from the Windows 7 Reisntallation DVD will be rejected in your system as Dell never sold it with Windows 7.

      The DVD drive in the E521 does it read other DVDs? You can try a lens cleaning CD as there may be some dust blocking the DVD laser. Its also possible that the DVD laser has failed (if it can’t read other DVDs this is likely the case):

  6. Thank you so much for your response.
    Yes, I have a product key.
    The other PC is old, too, a P4 powered unit, and it won’t read the disc either.
    The Dell E521 will not read it, and I installed the new HDD and tried with an XP disc so I know the DVD player is working OK. I think this is just too much BS and I’m going to send it back. The seller said I could install this on any computer blah blah blah.

    1. The Pentium 4 PC will likely have a CD drive only therefore won’t read a DVD. You can install using a retail .iso and make a bootable USB as instructed on this page.

      The important thing is the product key not the DVD.

  7. Thank you so very much for your interest and responses. I used burnaware (free) and installed the OS with no problems, except the last two times setup rebooted it booted to USB and I had to manually redirect the boot to HDD. Very simple, very easy to adapt to a new way, even for me.

  8. THANK YOU!!! Perfect helper. After hardware failure all I needed was a $50 new hard drive in my Dell laptop and this instruction set.

  9. HI philipyip,

    I just have a little concern for which I can’t really find an answer anywhere explaining this more thoroughly: If you look at the bootom of this tutorial from Sevenforums. com

    it states that for dell users the recovery partition will be obsolete after reinstall!
    I’d hate to loose that! Is this true ?

    I’d really like to reinstall windows 7 professional 64 bit oem on my studio1747 but using the Italian version ( since I’m a language enthusiast) but trying not to loose the recovery partition since it comes in soo HANDY! (off course I will also make recovery cd/dvd/usb before reinstalling, just in ase)


    Was also wondering if a reinstall or factory reset would effect my entire hard drive or only the system partition C: ie not my extended partition i’ve created to store data ??

    Many many thanks in advance since I know you’re the expert on this!


    1. If you go through the procedure of manual clean install with a Windows 7 .iso the recovery partition will be rendered useless. Moreover if you have extended and shrunk the main partition, Dell Backup and Recovery may not work, rendering your recovery partition already useless. It usually does not like users or software/malware resizing partitions on the main drive. If you delete all partitions during the clean installation you can install Dell Backup and Recovery after Windows Updates and driver installation and make a new recovery partition from your clean install.

      You can try updating to the latest version of Dell Backup and Recovery which has some fixes and enhancements to address some of these issues. If it installs okay and finds the recovery partition, make the Dell Backup and Recovery media. In the case of the Studio 1747 it will have a legacy non-UEFI BIOS so the Recovery Bootable USB is recommended (although that models probably modern enough to be able to also boot from an external hard drive). You can use it to restore the hard drive to factory state including the recovery partition. I’ve tested this even after a secure wipe with DBAN. Its advisable to maybe make 2 Bootable USBs as a backup just in case. You should ensure you use the latest version of Dell Backup and Recovery before proceeding.

      I am working on a Dell Backup and Recovery guide now that I have a device that is capable of capturing video within the Dell BIOS, it is still very much incomplete and I need some new Dell hardware with a UEFI BIOS for testing purposes:

      However I did make a guide restoring from a System Recovery USB a couple of days ago:

      You will see all the screens from the Recovery USB however my particular guide goes through deletion of everything and reverting to the factory state (the image of my clean installation). There are however options to perform the factory refresh instead of the factory recovery.

      I have to admit I have not tested the creation of other partitions using a third party utility or at clean installation or the factory refresh function. As mentioned I need some additional hardware to make a Dell Backup and Recovery Guide that I am satisfied with (and I have got some of this additional hardware). However I also need time and right now I am writing a PhD thesis moreover there should be a major update to Dell Backup and Recovery in March which would automatically make the guide obsolete. By that time I should have all the hardware I need and perhaps some time to do testing and write tutorials.
