Windows 10 RS1 is out for Windows Insiders on the Fast Track.
Note the absence of the watermark and the Windows Edition is now Windows 10 Pro and not Windows 10 Pro Insider Preview.
Windows 10 is boasted to be the last major release or version of Windows. It is promised to be a continuous stream of updates, fixes and enhancements. With the new continuous distribution of Windows 10 continuous testing is required and Microsoft are valuing the feedback from their enthusiasts i.e. those in the Windows Insiders program. You may opt to remain on the:
- Fast track (quick releases possibility of being very unstable) – Tier 2 Tester*
- Slow track (more stable releases but less frequent) – Tier 1 Tester
- Mainstream track (stable tested releases only) – General Consumer
* Requires use of a Microsoft Account if Upgrading via Windows Update but not if Clean Installing direct from .iso.
Determine your Edition of Windows and if you have a UEFI BIOS
Press [Windows] and [ r ] to bring up the run command:
In the run box type in
Then press ok.
Take a note of the OS Name. This will tell you what Edition of Windows 10 Insider Preview to Download. If you are running Windows 7 or Windows 8.x see the Windows 10 TH2 Upgrade Table to determine the correct Edition.
Take a note of the SMBIOS revision…
- If it is 2.7 or greater you should have a UEFI BIOS with SecureBoot.
- If it is 2.6 you might have an Early UEFI System (UEFI without SecureBoot) or only a Legacy BIOS. You will need to check your BIOS Setup*.
- If it is 2.5 you will have a Legacy BIOS.
- If it is 2.4 you will have a Legacy BIOS and the processor should be checked for 64 Bit compatibility.*
- If it has an SMBIOS of 2.3 or less its below minimum system requirements for Windows 10.
For Intel processors e.g. the G640 as shown, Google search Intel Ark G640. If the instruction set is 64 Bit you are all set to run Windows 10 64 Bit.
You have the System Manufacturer, System Model and BIOS Version/Date. You should compare this with the version offered by your Computer Manufacturer e.g. Dell, HP and Lenovo. See additional notes on Updating your UEFI BIOS and optimising the UEFI BIOS for Windows 10. Note if this is your sole computer do not save changes to your UEFI BIOS settings until you have finished making the Bootable USB.
Boot Mode and Secure Boot State
For systems with Windows 8 or Later installed you will have BIOS Mode and SecureBoot State shown. These technologies should be enabled where supported by the hardware. This information doesn’t show if you are currently running Windows 7. For a Windows 7 install in all cases SecureBoot will be disabled and the UEFI Boot may also be disabled. Again see additional notes on Updating your UEFI BIOS and optimising the UEFI BIOS for Windows 10. Note if this is your sole computer do not save changes to your UEFI BIOS settings until you have finished making the Bootable USB.
Downloading the Windows 10 Insider 14372 RS1 .iso
The Windows 14372 .iso is available to Download from Microsoft here:
Downloading from Techbench is simple:
The only thing to note regards Edition:
The Windows 10 Insider Preview Contains both Windows 10 Pro Insider Preview and Windows 10 Home Insider Preview.
Due to the fact that the Insider Preview is pre-release software that is released fast for a temporary basis there is no European Commission N Insider Preview or North Korean KN .iso likely as the build will have expired before the bureaucracy allows it to be released to Windows Insiders.
Creating a Bootable USB Flash Drive
With this .iso you may use Rufus to create a bootable USB:
Rufus does not need to be installed and can be run directly by double clicking on the application.
Accept the User Account Control Prompt:
The order that you use Rufus is important failure to perform the steps in the order listed may lead to an incorrectly created Bootable USB
1. Select the USB Device:
2. Load the .iso:
Press the button to load the .iso:
Select the .iso and select open:
3. Check the Checksums (optional).
Rufus has the option to check the checksums.
These should only be used if the .iso is downloaded from an unofficial source.
4. Rename the volume label (optional).
I like to include the build number and the architecture in my volume Label.
e.g. I use labels like:
5. Select the Partition Scheme and then Target System Type.
The GPT Partition scheme is recommended for a UEFI BIOS and has to be FAT32 formatted in order to pass SecureBoot.
6. Click Start
Wait until Rufus says READY then you can close it an use your Bootable USB.

If you are signed in with a Local Account and go to settings:
Then select Updates and Security:
It should state “Windows is Activated with a Digital License”.
This occurs if and only if the system has been made a Windows 10 Pro Device. In my case it says this with a system that’s used the 10130 Insider Preview Upgrade Path, a Windows 7 OEM system and a Windows 8.1 OEM system.
