What Were the Windows 10 Launch System Requirements?

When Microsoft officially launched Windows 10 in July 2015, the operating system was designed to run smoothly on hardware that was already supporting Windows 7 and Windows 8.1. To facilitate broad adoption and widespread upgrades, Microsoft maintained modest baseline hardware specifications, split primarily by 32-bit and 64-bit architecture needs.

Core Hardware Specifications

To install and run the original release of Windows 10, a PC needed to meet the following foundational hardware standards:

• Processor: 1 gigahertz (GHz) or faster processor, or a System on a Chip (SoC) compatible with SSE2, PAE, and NX/XD bit technologies.
• System Memory (RAM): 1 gigabyte (GB) for the 32-bit edition, or 2 GB for the 64-bit edition.
• Storage Space: 16 GB of free hard drive space for the 32-bit OS, or 20 GB for the 64-bit OS.
• Graphics Card: DirectX 9 or later compatible graphics device featuring a WDDM 1.0 (Windows Display Driver Model) driver.
• Display Resolution: A minimum display resolution of 800 x 600 pixels.

Firmware and Connectivity Requirements

In addition to the central computing components, Microsoft outlined baseline requirements for system security, firmware, and setup:

• Firmware: UEFI v2.3.1 Errata B with Microsoft Windows Certification Authority in the UEFI signature database was recommended for new devices utilizing Secure Boot.
• Internet Connection: An active internet connection and a Microsoft account were necessary to perform initial setup, retrieve system updates, and download certain features at launch.
