Downloading the ISO from Microsoft (via Rufus/Fido) is completely legal as long as you have a valid license. Sharing the ISO on file-sharing sites is copyright infringement. Using unactivated Windows is permitted by Microsoft but limits personalization.
Downloading the Windows 10 Version 1507 ISO (the original "Threshold 1" release from July 2015) is primarily done for legacy testing, benchmarking, or running specific older hardware. Because Microsoft has long since replaced this version with newer builds, obtaining a clean, official copy requires using specific archival tools. 💿 How to Download the ISO Since the standard Microsoft Download page
only offers the latest version (currently 22H2), you must use one of these reliable workarounds: Rufus (Easiest Method): The popular Rufus USB tool
has a built-in "Download" script. Open Rufus, click the arrow next to , change it to
, and then choose Windows 10 -> Version 1507 (Build 10240) to download the ISO directly from Microsoft's servers. Microsoft VLSC / Visual Studio Subscriptions:
If you have a business or developer account, you can still find Version 1507 listed under "Downloads" in the Visual Studio portal or the Volume Licensing Service Center. Third-Party Tech Benches: Sites like Adguard’s TechBench

If you are planning to install this version today, keep the following in mind: End of Life:
Version 1507 reached the end of servicing for Home and Pro editions in
. It no longer receives security updates, making it highly vulnerable if connected to the internet. Driver Compatibility:
Modern hardware (Intel 12th Gen+, NVIDIA RTX 30/40 series) often lacks driver support for Build 10240, which may lead to stability issues or "Inaccessible Boot Device" errors. Activation:
Standard Windows 10/11 digital licenses usually work, provided you install the correct edition (Home or Pro) that matches your key. The "LTSB" Exception:
If you are looking for the "lightweight" version of 1507, you are likely looking for Windows 10 Enterprise LTSB 2015
, which was supported for significantly longer than the standard consumer builds. Are you looking to install this on virtual hardware or a specific legacy machine
Windows 10 Version 1507 (codenamed "Threshold 1") was the initial public release of Windows 10 in July 2015. While it was a landmark release that bridged the gap between Windows 7 and 8, using an ISO of this version today is generally not recommended for primary use. Current Status & Security
End of Support: This version reached the end of service years ago. If you use it, your computer will remain vulnerable to modern security risks and viruses because it no longer receives security or quality updates. windows 10 version 1507 iso
Performance: While Windows 10 is generally faster on SSDs than older OS versions, 1507 lacks nearly a decade of optimizations found in later builds like 22H2. Why People Still Use 1507 ISOs
Lower System Overhead: It is significantly "lighter" than modern Windows 10 versions, lacking many of the background services, telemetry, and pre-installed apps (bloatware) added in later years.
Legacy Hardware: It is sometimes used on older PCs or for benchmarking to see the "purest" form of the Windows 10 kernel without later feature creep.
Archival/Testing: Developers or enthusiasts may use it in virtual machines to test software compatibility for the original Windows 10 environment. Technical Considerations
ISO Size: Microsoft's Windows 10 ISOs are often larger than 4GB, which can complicate creating bootable USBs on FAT32 systems, requiring NTFS or specific extraction tools.
Obtaining the ISO: Microsoft officially pushes the latest version via the Media Creation Tool. Finding a genuine 1507 ISO typically requires access to an MSDN/Visual Studio subscription or reputable third-party archives like Internet Archive.
