Dell Windows 7 64 Bit PSP2 Reinstallation .isos – April 2016 Media Refresh

I slipstreamed the Convenience Rollup (Pseudo Service Pack 2), Internet Explorer 11, the latest Intel USB 3.0 Drivers, the latest Intel Storage Controllers and NVMe drivers into my multi-lingual 64 Bit Dell Windows 7 Reinstallation .isos. For more details in their creation (advanced users see here). N.B. In the past I had slipstreamed more updates which made the .isos unnecessarily large and the additional updates I slipstreamed are available as new monthly security rollups (more details later).


The set of Windows 7 Reinstallation 64 Bit PSP2 .isos contain most European Languages:

OEM System Locked Preinstallation

These .iso images will apply Dell OEM System Locked Preinstallation (Dell offline BIOS based Product Activation).

Eligible Dell systems should have shipped with a Dell Windows 7 COA affixed to the system. You should the Dell Windows 7 Reinstallation .iso which matches the Windows 7 Edition on the COA:

Windows 7 COA

Alternatively a Windows 8 Pro OEM or Windows 10 Pro OEM sticker. In which case you are Licensed to install Windows 7 Pro via Downgrade Rights:

win10Pro Win8Pro

Systems with a Windows 8 Home OEM and Windows 10 Home OEM sticker are not eligible for Windows 7 (of any Edition) OEM SLP and Product Activation will fail without a Full Retail Key:

Win10Home Win8Home Win8Bing


To prevent the COA from fading the COA is likely residing in the battery compartment of Laptops and inside the computer cover of Desktops. Its advised to use your smartphone to take a picture of it before installation however you don’t need this key as the Dell Windows 7 OEM .isos will apply Dell OEM SLP and so will activate automatically offline automatically without asking for a Product Key:

Dell Windows 7 Reinstallation .isos

The .isos are unofficial and hence are only on an unofficial location. They may be located on Google Drive:

Newer Dell 6th Generation Intel Skylake systems may have an official .iso to download this officially from Dell see The Dell Skylake .iso.

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:


Select #:


This will give you the .iso checksums:


This will give you the various checksums and they should match the checksums below.

If they are different you will have an incomplete/corrupt download.

Creating a Bootable USB

You will require a 16 GB USB Flash Drive.

Once you have the .iso and Rufus downloaded, launch Rufus:


Select yes at the user account control prompt.

The order in which you use Rufus is very important…


To the top select your USB Device, it must be 8-16 GB.


Next although its at the bottom you must load the .iso:


Select the .iso you wish to make a Bootable USB from and select open:


If your SMBIOS is 2.7* or newer (a 2012 model or newer) then its preferable to use a UEFI Boot with Windows 7 64 Bit see Unified Extensive Firmware Interface.

* Some Business systems such as the OptiPlex/Latitude/Precision models with a SMBIOS version of 2.5 may have a UEFI Boot when their latest BIOS update is applied.

For a UEFI BIOS you should select the partition scheme as “GPT partition scheme for UEFI”. FAT32 should automatically be selected. When ready select Start:


For a system without a UEFI BIOS use the MBR Partition Scheme for Legacy BIOS.



Select Ok to acknowledge that you are going to format the USB flash drive:


Rufus will now make the installation media.


Once its completed the task, the progress bar will be full and it will say Ready below it. You can now close Rufus. You have your Windows 7 Service Pack 2 Reinstallation USB prepared:


Notes on Windows 7 Installation

To Install Windows 7 see my guide:

Monthly Security Update

Microsoft have been listening to user feedback on the annoyances of patching Windows 7.

They have started releasing Monthly Quality Rollups for Windows 7. The Latest one at this time of writing will give you all the Security Updates until the 12th of December 2016 and can be obtained from the Microsoft Update Catalog. I advise installing it immediately after clean installing Windows 7 64 Bit:×64

The Microsoft Update Catalog used to require Internet Explorer but has been updated so all browsers work with it.

Simply download the .msu file and install it then restart your computer when prompted.


Microsoft Security Essentials

The latest version of Microsoft Security Essentials for Windows 7 alongside its latest offline definition are available here. These can be installed post-installation after the latest Security Rollup:
