Windows 7 Reached End of Mainstream Support in January 2015. Extended Support lasts until January 2020. For more details see End of Support.
Despite these guides being Dell based. The instructions on this page worked for all Windows 7 OEM Licenses and Retail Licenses.
- Windows 7 with Service Pack 1 OEM and Retail Downloads from Microsoft’s Techbench
- English Checksums and File Sizes
- Create a Bootable USB for a UEFI BIOS or Legacy BIOS
- OEM System Locked Preinstallation
- Deleting the EI.cfg File (optional)
- Installation Notes
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.
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.
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:
Select yes at the user account control prompt.
Select the load .iso icon:
Select your .iso and select open:
This will give you the .iso checksums:
The English .isos they should match the following. If they do not you have an incomplete download.
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
Insert a 16 GB USB Flash Drive and launch Rufus:
Select yes at the user account control prompt.
Select the load .iso icon:
Select your .iso and select open:
For a UEFI system ensure the partition scheme is GPT for UEFI is selected and the file system is NTFS.
For a Legacy system ensure the partition scheme is MBR for Legacy BIOS and the file system is NTFS.
You will get a warning informing you that data on your USB will be wiped. Select OK:
Wait for Rufus to make your Bootable USB you will see the green progress bar:
When its finished it will say Ready.
Additional Notes for a UEFI BIOS
November 2010 Installation Media does not have support for hardware made in 2011-2016. You’ll likely need to incorporate USB 3.0 drivers into the boot.wim and install.wim files and Storage Controller drivers into the install .wim file otherwise your Windows 7 installation will fail. I’ve tried to make this as simple as possible see my guide Slipsteam of the Convenience Rollup, Internet Explorer 11, Storage Controllers and USB 3.0 support.
Note hardware manufactured in mid 2017 or later is not supported by Microsoft or Intel for Windows 7.
- Installation media without USB 3.0 driver support will lead to one being stuck on this screen with no response from the mouse or keyboard.
- Installation Media without Storage Controllers will result in the following error:
“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.”
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:
Its advised to install Windows 7 without a Product Key to initiate a 30 Day Trial Install and then to reapply OEM System Locked Preinstallation via a simple batch file.
Install Windows 7
To install Windows 7 see Windows 7 Installation in a UEFI BIOS or Legacy BIOS.
Notes on Windows Update
If the updates have not been slipstreamed into the installation media they should be applied immediately post-installation.
1. Service Stack:
2. Convenience Rollup:
3. Prequisite Updates for IE11:
5. The Latest Security Rollup from the Microsoft Update Catalog:
Simply download the .msu files and install them, then restart your computer when prompted. Note you must restart after each update.
